WebAug 20, 2006 · Computer Science, Mathematics In this paper, we study the security of 2R− schemes [17,18], which are the “minus variant” of two-round schemes. This variant consists in removing some of the n polynomials of the public key, and permits to thwart an attack described at Crypto'99 [25] against two-round schemes.

The affine cipher is very slightly more complicated than the Caesar cipher, but does not offer much more security. The number of possible keys is 12*26-1 = 311. This is very easy for a computer to simply search all possible keys and pick the best.
