WebThe generator makes use of modular arithmetic and works as follows: Setup. Given a security parameter \tau \in \mathbb {Z} as input, generate two random \tau -bit primes p, q where p = q = 3 mod 4. Set N = {\it { pq}} \in Z. Integers N of this type (where both prime factors are distinct and are 3 mod 4) are called Blum integers. Blum Blum Shub (B.B.S.) is a pseudorandom number generator proposed in 1986 by Lenore Blum, Manuel Blum and Michael Shub that is derived from Michael O. Rabin's one-way function.
