Séminaire Sécurité Loria (SSL) le 2 juillet

juillet 2, 2015 @ 13:30 - 14:30

Le prochain séminaire Sécurité Loria (SSL) aura lieu le jeudi 2 juillet, à 13h30 dans l’amphi C. Christian Grothoff d’Inria Rennes fera un exposé intitulé “The GNU Name System”.

Title :

The GNU Name System

Abstract :

In this talk, I will present the design of the GNU Name System (GNS), a fully decentralized and censorship-resistant name system.  GNS uses cryptography to provide a privacy-enhancing alternative to DNS and existing public key infrastructures (such as X.509 certificate authorities), while giving users the desirable property of memorable names.  The design of GNS incorporates the possibility of integration and coexistence with DNS. GNS builds on ideas from the Simple Distributed Security Infrastructure (SDSI), addressing a central issue with the decentralized mapping of secure identifiers to memorable names: namely the impossibility of providing a global, secure and memorable mapping without a trusted authority. GNS uses the transitivity in the SDSI design to replace the trusted root with secure delegation of authority, thus making petnames useful to other users, while operating under the strong adversary model represented by authoritarian state actors.


Christian Grothoff is leading the Décentralisé team at Inria Rennes. He maintains GNUnet, a network designed with the goal to provide privacy and security without the need for trusted third parties.  He earned his PhD in computer science from UCLA, an M.S. in computer science from Purdue University, and a Diplom in mathematics from the University of Wuppertal.
