Until a protocol is proven to provide the service intended, the list of possible attacks can never be said to be complete. 1. known-key attack. In this attack an adversary obtams some keys used previously and then uses this information to determine new keys. 2. Webset, covers a wide range of known-key attacks in literature. We apply this instance to the PGV compression functions, as well as to the Gr˝stl (based on two permu-tations) and Shrimpton-Stam (based on three permutations) compression functions, and show that these designs do not seriously succumb to any di erential known-key attack known to date. perth sheriff court telephone number
