One feature pertains to a method for generating a prime number by repeatedly generating a random number seed S having k bits, generating a random number R having n bits based on the seed S, where k is less than n, and determining whether the random number R is prime. The steps are repeated until it is determined that the random number R generated is prime, upon which the random number seed S used to generate the random number R is stored in a memory circuit. Later, the stored random number seed S may be retrieved from the memory circuit, and the prime number is regenerated based on the random number seed S. In one example, the random number R generated is further based on a secret key kS that may be stored in a secure memory circuit. |
