Chinese remainder theorem rsa attack
WebJan 1, 2002 · Abstract. We introduce a new type of timing attack which enables the factorization of an RSA-modulus if the exponentiation with the secret exponent uses the Chinese Remainder Theorem and Montgomery’s algorithm. Its standard variant assumes that both exponentiations are carried out with a simple square and multiply algorithm. WebRSA digital signatures based on the Chinese Remainder Theorem (CRT) are subject to power and fault attacks. In particular, modular exponentiation and CRT recombination are prone to both attacks. However, earlier countermeasures are susceptible to the ...
