Cryptanalysis of a 32-bit RC4-like Stream Cipher

Hongjun Wu

Abstract

Nawaz, Gupta and Gong recently proposed a 32-bit RC4-like stream cipher. In this paper, we show that the keystream generated from their stream cipher is not random. The keystream can be distinguished from random with only about 100 outputs (3200 bits) in 2 milliseconds on Intel Centrino 1.6GHz processor.
