Collision for 75-step SHA-1: Intensive Parallelization with GPU

E. A. Grechnikov and A. V. Adinetz

Abstract

We present a brief report on the collision search for the reduced SHA-1. With a few improvements to our previous work, directed at efficient parallelization on a GPU cluster, we managed to construct a new collision for 75-step reduced SHA-1 hash function.
