Freestart Collision for Full SHA-1
EUROCRYPT, pp. 459-483, 2016.
This article presents an explicit freestart colliding pair for SHA-1, i.e. a collision for its internal compression function. This is the first practical break of the full SHA-1, reaching all 80 out of 80 steps. Only 10ï¾¿days of computation on a 64-GPU cluster were necessary to perform this attack, for a runtime cost equivalent to approx...More
