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, in the group SPICY. He is also an honorary member of the Institut Universitaire de France.

Gildas Avoine is the president of the scientific council of ANSSI. He also heads the research activities in computer science at INSA Rennes (about 65 faculty members, Phd Students, Postdocs, and Engineers).

From 2021 to 2023, Gildas Avoine was the CNRS' Scientific Manager (jointly with CEA and Inria) of the funding programme "PEPR Cybersécurité", which has a budget of 65 million euros. From 2015 to 2021, Gildas Avoine was the director of the CNRS' scientific network in cybersecurity (GDR Sécurité Informatique), which 1300+ researchers are registered to. 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. From 2015 to 2020, he was the co-head of the research group EMSEC (Embedded Security and Cryptography) founded jointly with P.A. Fouque. EMSEC hosted up to 35 people and it was then splitted into two groups, namely SPICY and CAPSULE.

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, and deanonymisation.
I am glad to currently supervize or co-supervize five PhD students: Tristan Claverie (ANSSI/INSA), Olivier Gimenez (Orange/INSA), Diane Leblanc-Albarel (CNRS/INSA), Thomas Rokicki (CNRS/INSA), and Antonin Voyez (ENEDIS/UR1).
