We study cryptographic attacks on random Feistel schemes. We denote by m the number of plaintext/ciphertext pairs, and by k the number of rounds. In their famous paper [3], M. Luby...

A trapdoor based on an extension of the RSA trapdoor is proposed. The same function as in the RSA cryptosystem is used, i.e. x modn, but there is no restriction for the exponent t...
