If there is an integer a such that. then N is prime. This test is so simple that in practice the difficulty is quickly multiplying the large numbers involved.

Webb24 juli 2024 · 2.1 Proth Number. A natural number N is called a Proth number which is in the form of \(N=k\cdot 2^m+1\) where k is odd and \(k<2^m\). In particular, N is called a Proth prime if N is a prime number. Owing to its efficiency, a Proth prime is used as modulus for NTT. Proth number N has a special property for a modular multiplication.

In number theory, Proth's theorem is a primality test for Proth numbers. It states that if p is a Proth number, of the form k2 + 1 with k odd and k < 2 , and if there exists an integer a for which then p is prime. In this case p is called a Proth prime. This is a practical test because if p is prime, any chosen a has about a 50 percent chance of working, furthermore, since the calculation is mo… WebbNote that the probability of a number being prime is not the same as the question whether or not a number is prime.
