Collision Attack on the Waterfall Hash Function

Scott Fluhrer

Abstract

We give a method that appears to be able to find colliding messages for the Waterfall hash function with approximately $O (2^{70})$ work for all hash sizes. If correct, this would show that the Waterfall hash function does not meet the required collision resistance.
