Gildas Avoine

Gildas Avoine is professor of information security and cryptography at both the UCL in Louvain-la-Neuve (Belgium) and INSA Rennes (France) Previously, he was postdoctoral researcher at the MIT (USA) hosted by Ron Rivest in the CSAIL, and at the EPFL (Switzerland) in the LASEC headed by Serge Vaudenay, where he obtained a PhD degree in cryptography. Previously, he studied at the University of Caen (France) where he received a Bachelor degree in mathematics and Bachelor and Master degrees in computer science.
Gildas Avoine also leads training and consulting for companies, especially in his favorite field that is security of radio-frequency identification solutions (RFID).

My research activities relate to cryptography and information security, especially cryptographic protocols. My recent works addressed fair exchange protocols, time-memory trade-offs, non-adjacent form representations, but also and mostly authentication in radio-frequency (RFID) systems, from both theoretical and practical approaches.
