The Isomorphism of Polynomials (IP) [28], which is the main concern of this paper, originally corresponds to the problem of recovering the secret key of a C scheme [26]. Besides, t...
In this paper, we study the application of the function field sieve algorithm for computing discrete logarithms over finite fields of the form Fqn when q is a medium-sized prime po...
We discuss the following problem: Given an integer shared secretly among n players and a prime number e, how can the players efficiently compute a sharing of e-1 mod . The most in...
For the two last decades, people have tried to provide practical electronic cash schemes, with more or less success. Indeed, the most secure ones generally suffer from inefficiency...
In this paper, we introduce new concepts and methods for checking the correctness of control flow instructions during the execution of programs in embedded CPUs. Detecting and avoi...
