WebModular arithmetic. Much of modern cryptography is based on modular arithmetic, which we now brieﬂy review. We say that a≡ b(mod m) if the integers a and b diﬀer by a multiple of m. (In other words m (b− a)). The number m is called the modulus, and we say aand bare congruent modulo m. For example, 3 ≡ 17 (mod 2) because 17 − 3 is ...
