Description
Kedlaya described an algorithm for computing the zeta function of a hyperelliptic curve in characteristic p > 2 using the theory of Monsky-Washnitzer cohomology. Joint work with Jan Denef has resulted in 2 extensions of Kedlaya's original algorithm: the first extension can be used to compute the zeta function of a hyperelliptic curve in characteristic 2 and the second leads to a rather general method which works for any C_ab curve in any small characteristic. Furthermore, results obtained with an implemtation of both algorithms will be presented.

CryptoVerif: a computationally-sound security protocol verifier
Speaker : Bruno Blanchet - Inria
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[…]-
