Abstract
Disclosed are a method and a circuit for computing an error correction parameter associated with the Montgomery method, using an exponentiation of 2.sup.m*k+1 mod N, by an exponent equal to k*m(, N being a modulo, encoded on k*m bits, associated with a modular operation using the Montgomery method, the Montgomery method automatically generating an error that it is necessary to correct if it is desired to perform a modular operation that is correct.
