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...
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...
Collision resistant hash functions are an important basic tool for cryptographic applications such as digital signature schemes and integrity protection based on "fingerprinti...
In [ZMI89,ZMI90] two constructions for a collision resistant hash function were proposed. The first scheme is based on a block cipher, and the second scheme uses modular arithmetic...
Using a number field sieve, discrete logarithms modulo primes of special forms can be found faster than standard primes. This has raised concerns about trapdoors in discrete log cr...
