Web13 de dez. de 2011 · In particular, when working modulo a prime p, you are using the simplest form of finite fields: the Galois field GF(p). With a composite n, working modulo n gives less structure, Z/nZ is not a field, just a ring. However, it remains usable. Of course, when n is large and a product of two primes, working modulo n leads to RSA. Web22 de out. de 2014 · Our cryptosystem is based on arithmetic modulo so called Mersenne numbers, i.e., numbers of the form p = 2 n − 1, where n is a prime. These numbers have a simple and extremely useful property: for any number x modulo p, and y = 2 z, where z is a positive integer, x · y is a cyclic shift of x by z positions and thus the Hamming weight …
