| Popis: | In this paper, we describe attacks on the recently proposed Haraka hash functions. First, for the two hash functions Haraka-256/256 and Haraka-512/256 in the family, we show how two colliding messages can be constructed in about 216 function evaluations. Second, we invalidate the preimage security claim for Haraka-512/256 with an attack finding one preimage in about 2192 function evaluations. These attacks are possible thanks to symmetries in the internal state that are preserved over several rounds. IACR Transactions on Symmetric Cryptology, Volume 2016, Issue 1 |
