Using Wiener attack Found d: 4194341459785600727 ... the sheep industry – its recent evolutionWebAbstract. 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. the sheep killerWebAttack principle. First, when d is leaked, we can naturally decrypt all encrypted messages. We can even decompose the modulus N. The basic principle is as follows. We know ed ≡ 1 mod φ(n) e d ≡ 1 mod φ ( n), then φ(n) k = ed−1 φ ( n) k = e d − 1.
