How to test implementation of primality tests like Miller–Rabin?

WebSolution Manual for Cryptography & Network Security (McGraw-Hill Forouzan Networking)... WebSince 65 fails the Miller-Rabin Primality Test in base 2, we know that 65 is composite. We also know 2 is a witness to 65, but 8 is a nonwitness to 65. The Miller-Rabin Primality Test is signi cantly more accurate than the Fermat Primality Test.

WebSo a reasonable algorithm would be to sieve some numbers smaller than n (up to 2000 if you want to be on the safe side) up to some small bound, then check the remaining numbers with the Miller-Rabin test. Test any that pass with a primality-proving algorithm—do not use AKS as other answers have suggested; it is not fast in this range. WebJun 8, 2024 · This is a probabilistic test.
