VMPC Stream Cipher

Bartosz Zoltak

Abstract

The VMPC Stream Cipher is a simple encryption algorithm, designed as a proposed practical application of the VMPC one-way function. The general structure of the Cipher is based on an internal 256-element permutation. The VMPC Cipher, together with its Key Scheduling Algorithm, were designed in particular to eliminate some of the known weaknesses characteristic of the alleged RC4 keystream generator.

Note: The paper describes a stream cipher designed by Bartosz Zoltak as a practical application of the VMPC one-way function. New analyses results have been included
