A Security Evaluation of Whitenoise

David Wagner


This report studies the security of Whitenoise, a stream cipher invented by BSB Utilities Inc. "Even if we hypothesized the existence of some magic computer that could test a trillion trillion key trials per second (very unlikely!), and even if we could place a trillion trillion such computers somewhere throughout the universe (even more unlikely!), and even if we were willing to wait a trillion trillion years (not a chance!), then the probability that we would discover the correct key would be negligible (about (1/2)^1340, which is unimaginably small)."

Note: This is a security evaluation of a new generation stream cipher called Whitenoise. This technology has some unique features and strengths. To date there have been no systemic problems with this technology at all.
