Abstract: | In this article I analyze the function f(X) = A + X (mod 2**n) exclusive-or differential probability. The result, regarding differential cryptanalysis, is a better understanding of ciphers that use f(X) as a primitive operation. A simple O(n) algorithm to compute the probability is given. |
