The simplest form of Håstad's attack is presented to ease understanding. The general case uses the Coppersmith method. Suppose one sender sends the same message in encrypted form to a number of people , each using the same small public exponent , say , and different moduli . A simple argument shows that as soon as ciphertexts are known, the message is no longer secure: Suppose Eve intercepts , and , … WebA Timing Attack against RSA with the Chinese Remainder Theorem 111 [10]).

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.
