Abstract

Generating primes is a fundamental problem in modern cryptography. Deterministic primality tests work well for special integers such as Mersenne or Proth primes, but these forms are quite restrictive. In this paper, we give a direct method to construct new primes from known ones. Starting with a seed prime q1(mod3)q \equiv 1 \pmod{3}, we construct an integer N1(mod3)N \equiv 1 \pmod{3} satisfying (2N+1)23(modq)(2N + 1)^2 \equiv -3 \pmod{q}. We then prove that NN is prime using the structure of monogenic pure cubic fields K=Q(d3)K = \mathbb{Q}(\sqrt[3]{d}). The resulting test requires only a single modular exponentiation and runs in O~(log2N)\tilde{\mathcal{O}}(\log^2 N) time. Finally, we show how this construction extends to pure number fields of arbitrary prime degree.
