    Johan Bosma - Leiden University

We will describe how we are implementing Edixhoven's method for computing polynomials for the mod l Galois representations associated to modular forms. The computations are done in MAGMA, using modular symbols and numerical analysis. Recently, we have computed such polynomials for the mod 13 representation associated to Delta, the discriminant modular form of weight 12. In that case, we work with the modular curve X_1(13), which is of genus 2, and the polynomials have degrees 14 and 168.

    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[…]
