    Jean-Claude Belfiore - ENST

The need of high data rates on the radio channel (WiFi and its future for example) explains the increasing number of researchers working on space-time codes. Preparing Wireless IP systems, some companies and some researchers are promoting the use of non coherent space-time codes.<br/> We show that designing a non coherent space-time code is equivalent to finding some good packings on the Grassmann manifold. But the minimum distance of the packing is not a Euclidean distance and the codes need to be decoded with a "not too complex" algorithm. To solve this problem, we propose a new family of codes on the Grassmann manifold as well as the associated performances.

    CryptoVerif is a security protocol verifier sound in the computational model of cryptography. It produces proofs by sequences of games, like those done manually by cryptographers. It has an automatic proof strategy and can also be guided by the user. It provides a generic method for specifying security assumptions on many cryptographic primitives, and can prove secrecy, authentication, and[…]
