… In this paper, we demonstrate that SHA-1 collision attacks have finally become practical
by providing the first known instance of a collision. Furthermore, the prefix of the colliding …

… In this article, we give the first colliding pair for the full SHA-1 compression function (see
Table 1), which amounts to a freestart collision for the full hash function. This was obtained at a …

… This article presents an explicit freestart colliding pair for SHA-1… first colliding pair for the full
SHA-1 compression function (see Table 1-1), which amounts to a freestart collision for the full …

… Full size table … chosen-prefix collision for SHA-1 is not much more than a simple collision
search. Moreover our work has a strong impact in practice as chosen-prefix collision attacks are …

… the performance of collision search attacks. In the case of SHA-1, finding such characteristics
made differential collision search attacks on the full SHA-1 possible in the first place. To …

… All the collisions of reduced SHA-1 that we present were found within a few seconds of …
attacking various reduced versions of SHA-1 with more rounds, and shows that SHA-1 up to 53–…

… this nearcollision attack can be used to construct a SHA-1 identical-prefix collision attack …
Furthermore, we present the first SHA-1 chosen-prefix collision attack with a complexity of 277.1 …

… Figure 3: Skeleton of starting differential path for all blocks during the near-collision phase
of our CP collision attack on SHA-1 (only the first 20 steps are depicted). The MSB’s are on the …
