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. WebCryptography: Attacks on RSA, NON-RSA Encryption.
