Ctf wiener's attack
The Wiener's attack, named after cryptologist Michael J. Wiener, is a type of cryptographic attack against RSA. The attack uses the continued fraction method to expose the private key d when d is small.

Ctf wiener's attack
Did you know?
WebAbstract. Wiener has shown that when the RSA protocol is used with a decrypting exponent, d, which is less than N1=4 and an encrypting exponent, e, approximately the same size as N, then d can usually be found from the continued fraction approximation of e=N. We extend this attack to the case when there are many ei for a given N, all with small di.
