ICE (cipher): Standards & Overview

In cryptography, ICE (Information Concealment Engine) is a symmetric-key block cipher published by Matthew Kwan in 1997. The algorithm is similar in structure to DES, but with the addition of a key-dependent bit permutation in the round function. The key-dependent bit permutation is implemented efficiently in software. The ICE algorithm is not subject to…
