Abstract—The generate of “safe” primes p, where all prime divisors of p-1 are large prime divisors, is essential to avoid small subgroup attacks which are point out by two authors Chao Hoom Lim and Pil Joong Lee. An existing algorithm for generating such primes has also been presented by these two authors. However, the drawback of that method is that the algorithm does not always return safe prime numbers. Part of the reason for this is that the algorithm is not (and hardly) be thoroughly analyzed and evaluated mathematically. Therefore, the main purpose of this paper is to propose a new algorithm for generating safe prime numbers, including detailed mathematical evaluations.
