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.
