WebI am trying to cryptanalyse a cipher–text encrypted by Affine cipher. The encryption formula is: c = f ( x) = ( a x + b) mod m, where a and b are unknown constants; x is a plain-text symbol, and c the corresponding cipher-text symbol, both in range [ 0 … m − 1]; m = 26 is known.

An algorithm being probabilistic means that it is allowed to "throw coins", and use the results of the coin throws in its computations. This is reasonable because a realistic adversary has access to certain pseudo-randomness sources (such as the C rand () function). Of course, a probabilistic algorithm is not required to ...
