Abstract:
A method for protecting a generation, by an electronic circuit, of at least one prime number by testing the prime character of successive candidate numbers, including: for each candidate number: the calculation of a reference number involving at least one first random number, and at least one primality test based on modular exponentiation calculations; and for a candidate number having successfully passed the primality test: a test of consistency between the candidate number and its reference number.
