Summary :

After Diffie and Hellman's paper, there have been published many cryptosystems, where large composite numbers are used as the public keys, and the factorization of them are used as the secret keys. But, on the other hand, there also have been published many integer-factoring algorithms that factor composite numbers rapidly. So methodologies to construct primes that are strong for such algorithms are needed to guarantee the safety of such cryptosystems. Here we propose a randon polynomial time algorithm for constructing strong primes that uses a probabilistic primality testing algorithm.
