Attacks on RSA
A number of methods have been proposed for attacking the RSA cryptosystem. This article describes them.
Any efficient solution to the integer factorisation problem would break RSA; see the RSA article for discussion. The difficulty with that approach is that no efficient solution is known. Cracking a large (say 1024 bits or more) RSA key with current factoring algorithms is not practical, even with massive parallelism.
Weiner attack
Michael Weiner proposed an attack [1] based on continued fractions which is effective if the exponent in the secret key is small.
TWIRL
The Weizman Instiute Relation Locator [1], developed by Adi Shamir (The 'S' in RSA) and Evan Tromer, is a machine designed to speed up the seiving step in the number field seive technique for integer factorisation.
