Abstract:The family of Goppa codes is one of the most interesting subclasses of algebraic geometric codes. As the McEliece cryptosystem often chooses a random Goppa code as its key, knowledge of the number of inequivalent Goppa codes for fixed parameters may facilitate in the evaluation of the security of such a cryptosystem. In this talk we present a new approach to give an upper bound on the number of inequivalent extended irreducible binary Goppa codes.This is a joint work with Guanghui Zhang.
