WebJan 12, 2010 · We cryptanalyse here two variants of the McEliece cryptosystem based on quasi-cyclic codes. Both aim at reducing the key size by restricting the public and secret generator matrices to be in quasi-cyclic form. The first variant considers subcodes of a primitive BCH code. The aforementioned constraint on the public and secret keys implies … WebSo here we get 18a ≡ 12 (mod 2) and 18a ≡ 12 (mod13) or, reducing, 0a ≡ 0 (mod 2) and 5a ≡ 12 (mod13) The first is a tautology, and the second can be solved by multiplying by the inverse of 5 modulo 13, that is 8, giving a ≡ 5 (mod 13). That gives two possible a modulo 26: a can be 5 or 18. The second is obtained by adding the modulus ...
