SUMMARY:D3 seminar by Gabriele Castellano
DESCRIPTION:D3 seminar by Gabriele Castellano from Politecnico di Torino. \nTitle: « On the Orchestration of Dynamic Services over Distributed IT Infrastructures » \n  \nAbstract: \nEdge Computing is moving resources toward the network borders\, thus enabling the deployment of a pool of novel applications that benefit from the new distributed infrastructure. However\, due to the heterogeneity of such applications\, specific orchestration strategies need to be adopted for each deployment request. Each application can potentially require different optimization criteria and may prefer particular reactions upon the occurrence of the same event. This work proposes a Service-Defined approach for orchestrating cloud/edge services in a distributed fashion\, where each application can define its own orchestration strategy by means of declarative statements\, which are parsed into a Service-Defined Orchestrator (SDO).\nMoreover\, to coordinate the coexistence of a variety of SDOs on the same infrastructure while preserving the resource assignment optimality\, a fully Distributed Resources AssiGnment and OrchestratioN algorithm (DRAGON) is proposed\, which seeks optimal partitioning of shared resources between different actors.\nThe advantages of the Service-Defined orchestration approach have been evaluated over some representative edge use cases\, and convergence and performance properties of DRAGON have been measured on a prototype implementation\, assessing the benefits compared to conventional orchestration approaches. \n  \nBio: \nGabriele Castellano is a Ph.D. student from Politecnico di Torino\, where he received his Master’s degree in Computer Engineering in 2016. His research interests include service virtualization\, resource orchestration\, distributed optimization\, and software-defined networking. In 2017-2018\, he has been a research fellow at Saint Louis University\, where he worked on distributed algorithms for edge resource allocation. He is currently pursuing an internship at Telefonica I+D (Barcelona)\, on orchestrating Machine Learning based inference tasks at the edge of the network. \n

SUMMARY:Séminaire SSL : Emmanuelle Anceaume
DESCRIPTION:Emmanuelle Anceaume (CNRS\, équipe CIDRE\, IRISA) présentera ses travaux de recherche le jeudi 5 décembre à 13h30\, salle A008 dans le cadre du séminaire SSL. \nTitle: Abstractions for permissionless distributed systems \nAbstract: \nPermissionless distributed systems are distributed systems in which (i) the number of participants for carrying out the protocol is not known before hand\, and is not even known during the course of the execution\, (ii) the right to contribute (e.g.\, by proposing a new value of interest for the other participants) and to participate (e.g.\, by reading new decided values) is not controlled by a (trustworthy) third authority\, and (iii) participants communicate over a weakly connected communication topology (such as a peer-to-peer network). The permissionless blockchain technology exactly complies with such features.  During this presentation I will present some of the most important abstractions that allow to support the construction of such distributed systems. \nLa totalité du programme du séminaire SSL est disponible sur la page web : http://seminaire-securite.loria.fr/

SUMMARY:Séminaire SSL par Ralf Sasse
DESCRIPTION:Le prochain exposé du séminaire SSL aura lieu jeudi 28 novembre à 13h30\, salle A008. L’orateur sera Ralf Sasse\, de l’ETH Zurich. \n  \nTitle: Seems Legit: Automated Analysis of Subtle Attacks on Protocols that Use Signatures (joint work with Dennis Jackson\, Cas Cremers\, Katriel Cohn-Gordon) \n  \nAbstract: \nThe standard definition of security for digital signatures — existential unforgeability — does not ensure certain properties that protocol designers might expect. For example\, in many modern signature schemes\, one signature may verify against multiple distinct public keys. It is left to protocol designers to ensure that the absence of these properties does not lead to attacks. \nModern automated protocol analysis tools are able to provably exclude large classes of attacks on complex real-world protocols such as TLS 1.3 and 5G. However\, their abstraction of signatures (implicitly) assumes much more than existential unforgeability\, thereby missing several classes of practical attacks. \nWe give a hierarchy of new formal models for signature schemes that captures these subtleties\, and thereby allows us to analyse (often unexpected) behaviours of real-world protocols that were previously out of reach of symbolic analysis. We implement our models in the Tamarin Prover\, yielding the first way to perform these analyses automatically\, and validate them on several case studies. In the process\, we find new attacks on\nDRKey and SOAP’s WS-Security\, both protocols which were previously proven secure in traditional symbolic models. \n  \nLa suite du programme sera prochainement annoncée\, et sera également disponible en ligne au fur et à mesure sur seminaire-securite.loria.fr. \n

SUMMARY:D3 and D5 Seminar with Danielle Palosi (ETH Zurich)
DESCRIPTION:November\, Friday 15th at 10.30 am in room C005\,  Daniele Palossi from the ETH Zurich will give a talk for the in joint D3-D5 seminar. The general topic will be how to run a convolutionnal neural network on a tiny quadcopter (10cm / 27g) using a new kind of CPU architecture (PULP). The exact title of her talk is : PULP-DroNet: Open Source and Open Hardware Artificial Intelligence for Fully Autonomous Navigation on Nano-UAVs\n\nAfter the seminar\, Daniele will try to setup a demo in the “creativ’lab” arena (bat. C).\n\nAbstract: \n\nNano-size unmanned aerial vehicles (UAVs)\, with few centimeters of diameter and sub-10 Watts of total power budget\, have so far been considered incapable of running sophisticated visual-based autonomous navigation software without external aid from base-stations\, ad-hoc local positioning infrastructure\, and powerful external computation servers.\n\nIn this talk\, we present what is\, to the best of our knowledge\, the first 27g nano-UAV system able to run aboard an end-to-end\, closed-loop visual pipeline for autonomous navigation based on a state-of-the-art deep-learning algorithm\, built upon the open-source Crazyflie 2.0 nano-quadrotor. Our visual navigation engine is enabled by the combination of an ultra-low power computing device (the GAP8 system-on-chip) with a novel methodology for the deployment of deep convolutional neural networks (CNNs). We enable onboard real-time execution of the DroNet state-of-the-art deep CNN at 6 frame-per-second within 64mW and up to 18fps while still consuming on average just 3.5% of the power envelope of the deployed nano-aircraft. Field experiments demonstrate that the system’s high responsiveness prevents collisions with unexpected dynamic obstacles up to a flight speed of 1.5m/s. In addition\, we also demonstrate the capability of our visual navigation engine of fully autonomous indoor navigation on a 113m previously unseen path.

SUMMARY:D3 seminar: Vehicular Networks
DESCRIPTION:The next D3 seminar will take place on November 14th\, 13:30-14:30\, room B013. \nTitle : « Optimized resource management in Cognitive Radio Vehicular Networks with soft and hard reliability guarantees » by Nicola Cordeschi (Sapienza University of Rome) \n  \nAbstract: \nIn current vehicular networks\, the communication traffic flows typically generated by safety applications and routed in downlink over the available backbones are of burst-type\, presenting inter-arrival gaps of non-negligible time duration that can be opportunistically exploited by Vehicular Clients (VCs). Recent studies about the mobile computation offloading in real-life cloud-assisted scenarios point out that the usage of WiFi-based traffic offloading in place of 3G-assisted one may reduce the average energy consumption of current smartphones of about 55%. \nIn this seminar\, we focus on primary–secondary user resource-management controllers in cognitive radio (CR) vehicular networks\, for Vehicle-to-Infrastructure (V2I) based access scenario\, under hard and soft collision constraints\, where VCs equipped with heterogeneous CR-capabilities and energy budgets (playing the role of secondary users) opportunistically exploit the time and frequency holes of the traffic flow generated by the Service Provider\, and compete for acceding to the serving Roadside Units (RSUs) (the primary user of the Internet backbone)\, through WiFi connections. These bandwidth-demanding applications are expected to have a significant impact on the commercial success of Vehicular Communication (VC) and will contribute to accelerate its implementation and deployment. We will discuss the twofold objective of this kind of networks\, i.e. the joint maximization of the aggregate access goodput of the overall network and the average per-client access rates. One of the problems of conventional approaches is that\, even if they fulfill the collision probability constraints\, they may incur in quite long transients\, where the instantaneous collision-rate is definitely too high\, completely destroying the information. \nWe discuss and compare MAC strategies able to take into account the energy budget\, the parameters and the specific fading phenomena of the vehicular wireless channels in the optimization framework\, so as to self-acquire context information about the currently available bandwidth-energy resources\, and quickly adapt to the mobility-induced changes of the state of the vehicular network\, even in the presence of intermittent Vehicular-to-Infrastructure connectivity. We discuss different families of controllers and derive theoretical results about their hierarchy of performances (throughput-gain\, performance bounds\, and not immediately intuitive situations where the more constrained controllers we propose do not present any optimality gap compared to more standard less reliable approaches). After discussing conditions of applicability and advantages of each subclass\, we give some insight into probabilistic fairness constrained problems\, and controllers exploiting cognitive data-fusion techniques and fully distributed implementations able to adapt to unpredictable and abrupt changes of the network statistics\, without requiring any a priori knowledge of the vehicular traffic patterns. \n  \nBio: \nNicola Cordeschi received the PhD degree in Information and Communication Engineering from the Sapienza University of Rome in 2008. He received the master degree (summa cum laude) in Communication Engineering in 2004. His Ph.D. dissertation was on the adaptive QoS Transport of Multimedia over Wireless Connections via cross layer approaches based on the Calculus of Variations. He was Fellow Researcher with the DIET Dept.\, Sapienza University of Rome for ten years\, and Assistant Professor from 2009 to 2016 giving lectures in the topics of wireless communication\, modulation and digital communication\, signal processing\, coding and information theory. His research activity is focused on wireless communications and deals with the design and optimization of high-performance energy-efficient transmission systems for wireless multimedia applications\, distributed and scalable resource allocation and management for vehicular communications\, medium access control\, multi-antenna systems\, cross-layer optimization via the tools of convex optimization\, game theory and competitive optimality. \n

SUMMARY:D4 Seminar on Self-localization and mapping in dynamic\, acoustic environments
DESCRIPTION:Speaker will be Christine Evers from the Imperial College London. \nSound is used in nature to detect\, identify and track salient events\, to navigate\, and to self-localise. The ability to make sense of acoustic signals is therefore a fundamental prerequisite for robots and autonomous systems. Audition – the ability to hear – excels particularly in scenarios where lighting conditions are poor\, where salient events are outside of the line-of-sight\, and in crowded environments where sensors\, such as LIDAR and RADAR\, are unreliable. However\, due to the challenges affecting acoustic signals\, robot audition has\, to date\, received only limited attention in the research community. \nThis talk focuses on acoustic scene mapping for robot audition in order to address the questions: “What is around me?” and “Where am I?”. The first part of the talk addresses the practical challenges of tracking moving sound sources when microphone arrays are integrated on moving platforms. The second part addresses the self-localization of the moving microphone array in the acoustic scene map when prior knowledge of the array position and orientation are unavailable. To conclude\, extensions\, including multi-modal sensor fusion\, and future directions are discussed. \nMore about the department 4 on Natural Language Processing & Knowledge Discovery \n

SUMMARY:D3 seminar on Low Power Wide Area Networks for the Industrial Internet of Things
DESCRIPTION:The talk will be given by Dr. Dimitrios Zorbas from Tyndall National Institute.\nCurrent Industrial Internet of Things (IIoT) protocols suffer from short range links and sometimes long delay due to the multi-hop nature of their topologies. A Low Power Wide Area Network (LPWAN) solution such as the LoRaWAN can resolve those issues\, however\, the ALOHA-style transmission policy of those technologies makes the delivery of a large number of packets by a large number of nodes impossible . To avoid bursts of collisions and expedite data collection\, we propose scheduling of transmissions in time slots. We provide evidence through extensive experiments that time-slotted synchronous LPWAN communications are feasible under different node arrangements. Apart from that\, more and more industrial applications require battery-free solutions that last for ever. To tackle this issue\, energy harvesting techniques such as the wireless power transfer have been proposed to power-up energy constrained IoT devices. During the presentation a number of ideas will be given to achieve the battery-free goal in a dynamic and mobile industrial environment. \n  \nBiography\nDr. Dimitrios Zorbas holds a PhD in Computer Science from the University of Piraeus in Greece. He has worked as a post doctoral researcher at Inria Lille – Nord Europe and at University of La Rochelle in France. He is currently researcher at Tyndall National Institute after receiving a Marie Curie fellowship. He is author of more than 40 peer-reviewed publications in the area of computer communications\, energy efficiency in networks\, and secure communications. He has also worked in several national as well as FP7 and H2020 projects. He is member of the IEEE. \nMore about the department 3 : Netwoks\, Systems and Services \n

SUMMARY:Seminar on Protein : Didier Devaurs (Grenoble\, France)
DESCRIPTION:The next Capsid seminar will be held on Thursday\, September 26\, 2019 at 11H00 in room B013.\n\nOur invited speaker is Didier Devaurs (Grenoble\, http://www.linkedin.com/in/devaurs )\, details below. \nEfficient Strategies to Explore the Conformational Space of Proteins and Molecular Complexes \nDidier Devaurs\nPostdoctoral Research Associate\nUniv. Grenoble Alpes / Inria \nProteins are the main effectors of genomic information and are involved in a wide range of physiological and pathological processes. A protein’s\nfunction is known to be influenced or mediated by its interactions with other molecules. These interactions are often associated with changes in\nthe protein’s conformation (i.e.\, its 3D structure). Studying this structure-function relationship requires gathering information about a\nprotein’s conformational space. While experimental techniques have enabled the description of numerous molecular structures\, computational\nmethods are required to exhaustively explore the conformational space of proteins. However\, because of the curse of dimensionality\,\nconformational exploration remains a critical challenge in structural biology.\nIn this talk\, I will present three strategies (that can be combined) to mitigate the curse of dimensionality when computationally exploring the\nconformational space of a protein or a molecular complex. The first strategy consists of using coarse-grained conformational sampling\nmethods\, instead of more accurate but more computationally-expensive all-atom simulation methods. The second strategy consists of guiding the\nconformational exploration with experimental data. The third strategy consists of adopting a purely geometric abstraction of the\nconformational exploration problem to enhance the scalability of existing computational methods.

SUMMARY:Talk Ahmed Ali - Qatar Computing Research Institute (QCRI)
DESCRIPTION:Ahmed Ali from the QCRI (Qatar Computing Research Institute) will give a talk on Friday 20 at 10:00 in room C005.\nHe will present his work on Automatic speech recognition developed on 1200 hours of speech. \nAbstract:  \nDialectal Arabic speech is suffering from a lack of labelled resources and a lack of orthography. There are three main challenges in dialectal Arabic speech recognition: (1) finding labelled dialectal speech\, (2) building robust dialectal speech recognition with limited labelled and (3) evaluating speech recognition for dialects with no standard orthographic rules.\nMy talk is divided into three parts: \n\nThe first section addresses dialect identification using speech data\, and introduces our novel approach in combining acoustic\, lexical and phonetic features using deep learning.\nThe second section presents our effort in the Multi-Genre Broadcast challenges. In the MGB-2\, more than 1\,200 hours lightly supervised speech data has been used for training multi-dialect broadcast system. The MGB-3 and MGB-5 will highlight the effort in building dialectal challenge in the wild\, where limited dialectal multi-general YouTube data has been used for transfer learning.\nThe third part of my talk addresses our effort in evaluating dialectal speech with no standard orthographic rules. Our methods learn from multiple transcribers and align the speech hypothesis to overcome the non-orthographic aspect. We have also automated this process by learning from twitter data different writing and propose a new evaluation metric. Finally\, we tried to estimate the word error rate with no reference transcription using decoding and language features. We show that our word error rate estimation is robust for many scenarios with and without the decoding features.\n\nBiography :  \nAhmed Ali is a Principal Engineer at the Arabic Language Technologies group (ALT) at the Qatar Computing Research Institute (QCRI). His work interests are in the area of speech recognition and natural language processing. Ahmed completed his PhD at the University of Edinburgh and BSc at Cairo University. He joined QCRI in 2011.\nPrior to joining QCRI\, Ahmed worked for Nuance in Cambridge\, UK from 2006-2011. Before Nuance\, Ahmed worked for six years at different IBM labs\, including two years at Watson\, USA\, labs. His current research on speech recognition has led to the development of state-of-the-art multi-dialect Arabic speech recognition: QCRI advanced transcription system (QATS). QATS is used by Al-Jazeera to transcribe their online content. DW and BBC have been using QATS. Ahmed’s team has won first place in the worldwide MGB-2 speech recognition competition. He also won the prestigious Qatar Foundation Best Innovation Award in 2018.

SUMMARY:Seminar OLKi : "Ontology applied to data sharing"
DESCRIPTION:Adrien BARTON\, researcher at the Institut de recherche en informatique in Toulouse  will come at Loria for a philosophy-informatics seminar on Sept. 19th at 2pm in LORIA in room A008. \nThis seminar is part of the LUE project Open Language and Knowledge for Citizens and is initiated by our colleagues from the Archives Henri-Poincaré Lab. \nOntology applied to data sharing\n\nApplied ontology is a field at the crossroads of various disciplines\, including computer science and philosophy. It aims to systematically develop general categorizations that promote semantic interoperability of data (that is\, ensuring the preservation of the meaning of data when it is transmitted from one system to another). An applied ontology defines the categories of entities relevant to a field of knowledge\, and sets out formal axioms that clarify the relationships between these entities. \nAn ontology can be represented as a computer file – the OWL (Web Ontology Language) format being frequently used today. The field of biomedical ontologies is particularly active\, with the continued development of a large set of interoperable biomedical ontologies\, the OBO Foundry (http://www.obofoundry.org/). But ontologies are also widely used in many other fields (engineering\, internet of things\, geographic information systems\, environment\, ecology\, etc.). \nI will show how philosophical work on causality or the nature of informational entities can support the development of coherent ontologies\, considering various examples from biomedical ontology. I will briefly present the Quebec PARS3 project for a learning health system\, based on these ontologies\, which aims to support a coupling between care and research activities. \n

SUMMARY:Séminaire SSL : M. Korczynski (LIG - Grenoble) "Internet-wide Measurements for Cybersecurity : The Case of DNS Zone Poisoning"
DESCRIPTION:Current communication networks are increasingly becoming pervasive\, complex\, and ever-evolving due to factors like enormous growth in the number of network users\, continuous appearance of network applications\, increasing amount of data transferred\, and diversity of user behavior. Therefore\, there is a great need for comprehensive Internet-wide measurements for cybersecurity. Critical facts about the Internet security\, such as “Which domain registries are abused by the cybercriminals the most?” or « Which Internet Service Providers do not deploy source IP address filtering\, facilitating massive DDoS attacks? » remain poorly quantified. \nIn this talk\, we will discuss a number of examples of measurement studies of the domain name space. In particular\, we will explore an attack against configuration files of poorly maintained name servers allowing\, for example\, domain hijacking. We refer to this type of attack as to « zone poisoning ». The attack is as simple as sending a single RFC compliant DNS dynamic update packet to a misconfigured server. In the simplest version of an attack\, a miscreant could replace an existing A or MX DNS resource record in a zone file of a server and point the domain name to an IP address under control of an attacker. We will present the global measurement study of the vulnerability. To assess the potential impact of non-secure dynamic updates\, we scanned 290 million domains worldwide and found that among the vulnerable domains are governments\, banks and health care providers\, demonstrating that the threat impacts important services. \nWe have also issued notifications for website owners\, DNS service providers\, and network operators\, suffering from non-secure DNS dynamic updates to assess which mechanisms are more effective at remediating the vulnerability. After the introduction of the General Data Protection Regulation (GDPR) some registration information is\, however\, no longer displayed in the public WHOIS data. Therefore\, we also assessed the effectiveness of alternative communication channels and issued notifications to national CERTs. \nVia our study of the zone poisoning attack and subsequent notifications to affected parties and respective intermediaries\, we aimed to improve the security of the global DNS ecosystem and test alternative methods to contact affected parties after the introduction of the GDPR regulation.

SUMMARY:Talk Hiroaki Wagatsuma (Kyushu Institute of Technology\, RIKEN) on Brain-inspired robotics
DESCRIPTION:Hiroaki Wagatsuma (Kyushu Institute of Technology\, RIKEN) will be at Loria until June 28th. He will give a talk entitled « Brain-inspired robotics: Neural Dynamics for the Body Coordination and Interactions with the Environment » on Wednesday 19 June\, 10:00am in room C005. \nAbstract\nThe first issue that he tackled was the elucidation of the mechanism how different time scales of a behavior and synapses are associated according to the rhythm and he currently extended it to the question of how a rhythm (a specific type of the limit cycle in the system) transits to the other\, dynamically and sophisticatedly\, i.e. a structural design of the trajectory or self-organization of multiple rhythms for a complex function. For example\, a synchronous motion spontaneously appears in communication between persons faced each other and their motions differentiate as time advances because they need to express the own expressions each other. A typical example is an interactive game with motions. For judging or proceeding from a stage to the next stage\, the counterpart with a different motion have to synchronize at some moment\, which is a result to compete and determine which is winner\, or looser. A possible hypothesis is that such a quasi-equilibrium state is emerged from the coupling between the behavioral coordination and neuronal dynamics including the coordination and a conflict in the internal decision-making process. He discussed on the issue in the talk.

SUMMARY:Séminaire SSL : L. Hirschi (INRIA - LORIA) "Security and Privacy of 5G AKA vs. Formal Verification"
DESCRIPTION:Mobile communication networks connect much of the world’s population. The security of every user’s calls\, SMSs\, and mobile data\, depends on the guarantees provided by the Authenticated Key Exchange protocols used. For the next-generation network (5G)\, the 3GPP group has standardized the 5G AKA protocol for this purpose.\nWe first discuss a comprehensive formal model and security analysis of 5G AKA (CCS’18). We extract precise requirements from the 3GPP standards defining 5G and we identify missing security goals. Using the security protocol verification tool Tamarin\, we conduct a full\, systematic\, security evaluation of the model with respect to the 5G security goals. Our evaluation automatically identifies the minimal security assumptions required for each security goal and we find that some critical security goals are not met\, except under additional assumptions missing from the standard. Finally\, we make explicit recommendations with provably secure fixes for the attacks and weaknesses we found.\nWe then discuss a privacy vulnerability we manually found on 5G AKA but that also affects the 3G and 4G versions of AKA (PETS’19). Despite the practical relevance of this new attack\, no prior automated analyses were able to find it. Even a posteriori\, automatically finding the privacy attack and establishing claims about potential fixes are challenging. We discuss why is so and identify some remaining scientific and technical obstacles.

SUMMARY:TALC seminar : talk of Angelique Monnier
DESCRIPTION:Date: Tuesday\, 28th May 2019 at 2pm\nPlace: LORIA\, room A008\nSpeaker: Angeliki Monnier (Université de Lorraine – CREM) \nTitle: Understanding ICT uses as “habitus”? \nAbstract:\nThis presentation will address the uses of information and communication\ntechnologies (ICT)\, particularly social media\, as “habitus”\, inspired by\nPierre Bourdieu’s Field Theory. My thesis draws on an empirical study\,\nconducted on the professional network LinkedIn\, which focused on\ndiscussion groups held by Greek and French expatriates\, respectively.\nMore particularly\, analysis has shown that discussions are not conducted\nin the same way between Greek and French expatriates. For the former\,\nthe question is the image of the country\, tarnished by the economic\ncrisis. For the latter\, it is the direct contact with the Other\, on the\nbackground of the French colonial past\, which colors the discussions.\nMy argument is that the representations and “patterns of thought” that\ndetermine how Greek and French expatriates get involved in a discussion\ngroup within a professional social media are socio-historically\ndetermined and could be associated to distinct habitus. Following Pierre\nBourdieu’s theory\, these divergences could be related to the positions\nthat Greece and France hold within the international migration field.

SUMMARY:Séminaire SSL : D. Aranha "Return of the Insecure Brazilian Voting Machines"
DESCRIPTION:This talk presents a detailed and up-to-date security analysis of the voting software used in the last Brazilian elections by more than 140 million voters. It is mainly based on results obtained in a restricted hacking challenge organized by the Superior Electoral Court (SEC)\, the national electoral authority. During the event\, multiple serious vulnerabilities (hard-coded cryptographic keys and insufficient integrity checks\, among others) were detected in the voting software\, which\, when combined\, compromised the main security properties of the equipment\, namely ballot secrecy and software integrity. We trace the history of the vulnerabilities to a previous security analysis\, providing some perspective about how the system evolved in the past 7 years. As far as we know\, this was the most in-depth compromise of an official large-scale voting system ever performed under such severely restricted conditions. \nJoint work with Pedro Y. S. Barbosa\, Thiago N. C. Cardoso\, Caio Lüders and Paulo Matias. \n\nDiego F. Aranha is an Assistant Professor in the Department of Engineering at Aarhus University. He holds a PhD degree in Computer Science from the University of Campinas and has worked as a visiting PhD student for 1 year at the University of Waterloo. His professional experience is in Cryptography and Computer Security\, with a special interest in the efficient implementation of cryptographic algorithms and security analysis of real-world systems. He coordinated two teams of independent researchers capable of detecting and exploring vulnerabilities in the software of the Brazilian voting machines during controlled tests organized by the national electoral authority.\nHe received the Google Latin America Research Award for research on privacy twice\, and the MIT TechReview’s Innovators Under 35 Brazil Award for his work in electronic voting.

SUMMARY:Exposé Etienne André - D2
DESCRIPTION:Etienne André\,de l’Université Paris 13 fera un exposé le vendredi 3 mai à 14h00 en salle A008 intitulé « Monitoring real-time systems under uncertainty » \nAbstract : \nGiven a log and a specification\, timed pattern matching aims at exhibiting for which start and end dates a specification holds on that log. For example\, « a given action is always followed by another action before a given deadline ». This problem has strong connections with monitoring real-time systems. We address here timed pattern matching in presence of an uncertain specification\, i.e.\, that may contain timing parameters (e.g.\, the deadline can be uncertain or unknown). That is\, we want to know for which start and end dates\, and for what values of the deadline\, this property holds. Or what is the minimum or maximum deadline (together with the corresponding start and end dates) for which this property holds.I  will first give a brief introduction to parametric timed model checking. Then I will report on a framework for timed pattern matching based on parametric timed model checking. In contrast to most parametric timed problems\, the solution is effectively computable\, and we perform experiments using IMITATOR to show the applicability of our approach. \n

SUMMARY:Exposé d'Ana Roxin (D4)
DESCRIPTION:Ana Roxin\, candidate sur le poste de prof à l’IUT\, viendra faire un exposé lundi 29 avril à 11 heures\, en salle A008.\n\n Titre : \n« Raisonnement et connaissances – à la recherche de l’équilibre entre expressivité et efficacité »\n\nAuteur : \nAna ROXIN\, MCF HDR 27e section du CNU\, Univ. Bourgogne Franche-Comté (UBFC)\, Laboratoire d’Informatique de Bourgogne (LIB) EA7534\n\nRésumé: \n\nLe séminaire adresse le domaine de l’IA symbolique\, plus précisément l’ingénierie des connaissances ou la représentation de connaissances métier de manière à ce qu’un ordinateur puisse les interpréter et les manipuler\, comme le ferait un humain\, et tout en assurant l’efficacité d’implémentation. Après un bref résumé de mon parcours\, les contributions présentées concernent la modélisation de savoir-faire métiers avec des approches formelles\, décidables et en intégrant une sensibilité au contexte (de l’utilisateur ou d’utilisation). En relation avec ce domaine\, de nombreuses questions existent : comment modéliser de manière expressive et décidable une connaissance ? Comment identifier des connaissances vraies\, avec de la valeur dans un environnement de traitement massif de données ? Comment dépasser les limites de l’hétérogénéité sémantique dans un environnement fortement distribué ? Comment savoir si deux représentations « parlent de la même chose »\, si elles définissent la « chose » de la même manière ou si elles présentent des points de vue concurrents ou alors approximatifs ? Mes recherches s’efforcent de répondre à ces problématiques en utilisant les technologies du « Web sémantique ». Je présenterai mes contributions en termes de conception et implémentation d’approches permettant de simuler un raisonnement humain sur des connaissances réparties\, notamment notre approche de fédération faiblement couplée d’ontologies.

SUMMARY:Exposé Imed Laaridh (D4)
DESCRIPTION:Imed Laaridh qui candidate au poste de maitre de conférences à CentraleSupélec fera un exposé au Loria mercredi 24 avril en salle C005 à 14h. \n  \nTitre: « Traitement automatique et mesure d’intelligibilité de la parole pathologique » \nRésumé: \nL’intelligibilité de la parole est au cœur des interactions humaines. La problématique de son évaluation intéresse particulièrement la qualité de la transmission de la parole à travers différents milieux ou transducteurs\, la compréhensibilité de la parole en cas de déficit de production ou de perception de la parole par un individu\, la compréhensibilité des langues étrangères. \nDans la pratique clinique\, l’évaluation perceptive reste le moyen le plus utilisé pour la mesure de l’intelligibilité de la parole. Cependant\, cette évaluation présente plusieurs limites notamment son caractère subjectif et son coût (en temps et en ressources). \nCette présentation portera sur différentes applications des outils de traitement automatique de la parole sur de la parole pathologique. Les objectifs étant la mesure de la qualité de prononciation (au niveau phonème)\, la mesure objective de l’intelligibilité de la parole et la caractérisation des pathologies dans le cadre d’aide au diagnostic. \n

SUMMARY:MALOTEC Seminar
DESCRIPTION:For the next MALOTEC seminar\, Valia Mitsou\, who is a candidate for the position of associate professor in CentraleSupelec will give a presentation at LORIA on Tuesday April 23 at 11am in room A008 \nPresentation of the speaker : \nValia Mitsou\nUniversité Paris Diderot\nInstitut de Recherche en Informatique Fondamentale (IRIF) \nTitle: Limitation of treewidth for problems beyond NP \nAbstract: In this seminar\, we take a closer look at the parameterized complexity of problems belonging in Σ^p_2 and Π^p_2\, the second level of the polynomial hierarchy. We provide tight fine-grained bounds on their complexity with respect to the most important structural graph parameter\, the treewidth. We observe that these problems exhibit similar behavior: we show that a variety of diverse problems including ∃∀SAT\, Choosability\, as well as various problems from AI such as Abduction and Abstract Argumentation\, while they admit a $2^{2^{O(tw)}}$ algorithm\, they cannot be solved in time $2^{2^{o(tw)}}$ under the Exponential Time Hypothesis. \nFor more information

SUMMARY:MALOTEC seminar : Lydia Boudjeloud-Assala
DESCRIPTION:  \n=========================================================\nMALOTEC Seminar: Thursday April 04 2019\, 2pm\, Room C005 \nLydia Boudjeloud-Assala\nUniversité de Lorraine\nLoria \nTitle: Human in the loop: Visual -massive and temporal- data mining \nAbstract: I will present a review of my research on cooperative\napproaches combining interactive visualization methods and automatic\nmethods (attributes Selection\, Clustering\, Biclustering\, and outlier\ndetection) for the knowledge discovery in massive and temporal data. I\nwill present different possibilities to involve the user in the data\nmining process in order to improve his confidence and understanding in\nthe models or obtained results. New challenges for these methods\, which\nmust be able to handle not only increasing amounts of data but also data\nthat can change over time\, will also be presented and discussed. \nFor more information \nFurther MALOTEC Seminars \n  \n

SUMMARY:SSL Seminar
DESCRIPTION:Next SSL seminar will take place on Thursday\, April 4th at 1.30 pm in room A008. \nGilles Barthe (MPI Bochum) will give a presentation entitled « Computer-aided cryptography ». \n \nWe need cryptography that we can trust. Yet the design\, analysis\, and implementation of cryptographic libraries is a challenging task\, that requires insights across various areas of mathematics and computer science. Computer-aided cryptography is a young research area which\nuses formal methods for exploring the design space of cryptographic constructions and for delivering zero-defect\, side-channel resistant\, cryptographic libraries. The talk will give an overview of our work in computer-aided cryptography and discuss some of the challenges and opportunities in cryptography and beyond.

SUMMARY:Séminaire D3: Ingénierie multi-agent des collectifs cyber-physiques
DESCRIPTION:Le prochain séminaire D3 aura lieu le mardi 2 avril à 10h en salle A008. \nVoici le titre et le résumé: \nTitre : Ingénierie multi-agent des collectifs cyber-physiques (par Jean-Paul Jamont – Univ. Grenoble Alpes) \nRésumé : Les collectifs cyber-physiques sont des systèmes embarqués en réseau dans lequel les nœuds logiciels et matériels ont une autonomie de décision et coopèrent spontanément afin de participer à l’accomplissement d’objectifs du système global ou de pallier des manques de connaissances ou de compétences individuelles. Ces objectifs portent notamment sur l’état de leur environnement physique. Cette présentation introduit les nombreux défis posés par leur conception et propose une ingénierie de ces collectifs basée sur une démarche\, des modèles et des outils multi-agents. Plus loin l’ingénierie de leur couplage permettra d’aborder la notion de systèmes de systèmes cyber-physiques.
