Gildas Avoine


INSA Rennes

Gildas Avoine is a full professor of information security and cryptography at INSA Rennes (France) and he performs his research at IRISA. He is also an honorary member of the Institut Universitaire de France.

At IRISA, Gildas Avoine founded with P.A. Fouque the research group on Embedded Security and Cryptography (EMSEC). He was the co-head of the group from 2015 to 2020. Gildas Avoine is also the director of the CNRS' scientific network in cybersecurity (GDR Sécurité Informatique), which 1300+ researchers are registered to, and the president of the research council of ANSSI. From 2014 to 2018, he was the chair of the European COST Action Cryptacus (IC1403) about cryptanalysis in ubiquitous computing systems, which involved 30 countries.

Previously, Gildas Avoine was a professor at the UCL in Louvain-la-Neuve (Belgium), a postdoctoral researcher at the MIT (USA) hosted by Ron Rivest in the CSAIL, and a PhD student at the EPFL (Switzerland) in the LASEC headed by Serge Vaudenay, where he obtained a PhD degree in cryptography. He studied at the University of Caen (France) where he received a Bachelor degree in mathematics and Bachelor and Master degrees in computer science.

Research Interests

My research activities are related to cryptography and information security, especially (but not only) cryptographic protocols. My current work addresses cryptanalytic time-memory trade-offs, cryptanalysis of secure protocols as Lorawan and SCP02, distance-bounding protocols, memory carving in embedded devices, and deanonymisation.
