Masking of a calculation performed according to an RSA-CRT algorithm

摘要

The method involves obtaining a result from two modular exponentiation calculations and from recombination process, where each modular exponentiation calculation provides partial result that is a modulo of two co prime numbers. Digital quantity is added to the partial result before recombination process, where the digital quantity is lower than difference between co prime numbers. Effect of the digital quantity is cancelled after recombination process.
