4. Algorithmic number theory
4.1 Factoring
We present Pollard's p – 1 algorithm. We aim to give the idea implemented in this algorithm rather than the details.
Let n be the number to be factorized. Let p be a prime factor of n : n = p k m
where m is prime to p and assume that all prime factors of p – 1 are less than a small bound R. Let us denote by , for each prime number q R, the integer...
