This document describes the RC5 encryption algorithm, a fast symmetric block cipher suitable for hardware or software implementations. A novel feature of RC5 is the heavy use of da...
This paper shows that the actual proposal for an unbalanced Feistel network by Schneier and Blaze is as vulnerable to differential cryptanalysis as the DES. 1 McGuffin Schneier and...
In this paper we present an improvement of the differential attack on hash functions based on block ciphers. By using the specific properties of the collision attack on hash functi...
We describe the results of experiments on the use of multiple approximations in a linear cryptanalytic attack on FEAL; we pay particular attention to FEAL-8. While these attacks on...
