The failure of McEliece PKC based on Reed-Muller codes.

I. V. Chizhov and M. A. Borodin

Abstract: This paper describes new algorithm for breaking McEliece cryptosystem, built on Reed-Muller binary code $RM(r, m)$, which receives the private key from the public key. The algorithm has complexity $O(n^d+n^4log_2n)$ bit operations, where $n=2^m, d=\text{GCD}(r,m-1).$ In the case of $\text{GCD}(r,m-1)$ limitation, attack has polynomial complexity. Practical results of implementation show that McEliece cryptosystems, based on the code with length $n=65536$ bits, can be broken in less than 7 hours on a personal computer.
