Classical Attacks on a Variant of the RSA Cryptosystem

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.
