Cryptanalysis of the Sidelnikov Cryptosystem

Download infoscience.epfl.ch

We present a structural attack against the Sidelnikov cryptosystem [8]. The attack creates a private key from a given public key. Its running time is subexponential and is eﬀective if the parameters of the Reed-Muller code allow for eﬃcient sampling of minimum weight codewords. For example, the length 2048, 3rd-order Reed-Muller code as proposed in [8] takes roughly an hour to break on a stock PC using the presented method.
