Polynomial Time Attack on Wild McEliece Over Quadratic Extensions
Alain Couvreur and Ayoub Otmani and Jean-Pierre Tillich
Abstract: We present a polynomial time structural attack against the McEliece system based on Wild Goppa codes from a quadratic finite field extension. This attack uses the fact that such codes can be distinguished from random codes to compute some filtration, that is to say a family of nested subcodes which will reveal their secret algebraic description.
