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. Web6 de ago. de 2012 · In RSA, the function used is based on factorization of prime numbers however it is not the only option ( Elliptic curve is another one for example).
