Lattice Gas Symmetric Cryptography
Lattice gas cellular automata (Lgca) are particular cellular automata that imitate the behavior of par- ticles moving on a lattice. We used a particular set of Lgca... -
Use of crypto based identifiers for IPv6 security
IPv6, next Internet protocol after IPv4, is under deployment in the Internet. It is strongly based on the Neighbor Discovery Protocol (NDP) mechanism. First, it allows... -

Security by chaotic dynamics of wireless LANs at the MAC layer
The security of wireless sensor network is a growing field of research hampered by limited battery life time and computing constraints. The originality of this thesis... -
Broadcast Encryption with Traitor Tracing
In this thesis, we look at definitions and black-box constructions with efficient instantiations for broadcast encryption and traitor tracing. We begin by looking at the... -

Cryptanalysis of Symmetric-Key Primitives Based on the AES Block Cipher
In this thesis, we are interested in the cryptanalysis of some symmetric primitives using the structural concepts of the current encryption standard AES. We begin by... -
Pairing computation and arithmetic of elliptic curves for cryptography
While first used to solve the Discrete Logarithm Problem (DLP) in the group of points of elliptic curves, bilinear pairings are now useful to construct many public key... -

Algorithms of discrete logarithm in finite fields
In this thesis we study at length the discrete logarithm problem in finite fields. In the first part, we focus on the notion of smoothness and on ECM, the fastest... -
Arithmetic recodings for ECC cryptoprocessors with protections against side-c...
This PhD thesis focuses on the study, the hardware design, the theoretical and practical validation, and eventually the comparison of different arithmetic operators...
