摘要
The invention relates to a countermeasure method in an electronic component which uses an RSA-type public key cryptographic algorithm. A first countermeasure method consists of using a random calculation for each new execution of the decryption algorithm with CRT. The calculations are made modulo p*r and q*r, r and t being random numbers. A second countermeasure consists of making the recombination random using the CRT theorem.
