Breaking the Stream Cipher Whitenoise

Hongjun Wu

Abstract

Whitenoise is a stream cipher with specification given at http://eprint.iacr.org/2003/249. In this paper, we show that Whitenoise is extremely weak. It can be broken by solving about 80,000 linear equations. And only about 80,000 bytes keystream are needed in the attack.
