Most of the attacks against (reduced) SHA-2 family in literature have used local collisions which are valid for linearized version of SHA-2 hash functions.

In this work, we study several properties of the SHA-2 design which have been utilized in recent collision attacks against reduced round SHA-2.

This analysis explains in a unified way the recent attacks against reduced round SHA-2 in a general class of local collisions and shows that the previously ...
