<p>The invention concerns a method for generating electronic keys from two integers a, b, the method comprising a step which consists in verifying the co primality of said numbers a, b. The invention is characterised in that said verification comprises the following operations: A) calculating the modular exponentiation algr;(b)modb, wherein lgr; is the Carmichael function; B) verifying that said modular exponentiation is equal to 1; C) storing the pair a, b when equality is verified and reiterating with another pair otherwise. The invention is applicable to microprocessor smart cards with arithmetic processor.</p> |
