In this paper we look at the statistical decoding attack on the McEliece cryptosystem from [4]. The statistical decoding algorithm is a probabilistic algorithm for correcting errors in random codes. It uses precomptuations to provide faster error correction than the classical general decoding algorithms. We analyze the success probability of the algorithm and show how to improve it. Further, we show that the algorithm may not be used to attack the McEliece cryptosystem, due to the large amount of precomputation needed.
