IACR Transactions on Symmetric Cryptology, 2016 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.

Breaking a Chaotic Cryptographic Scheme Based on Composition Maps
, 2009 Recently, a chaotic cryptographic scheme based on composition maps was proposed. This paper studies the security of the scheme and reports the following findings: 1) the scheme can be broken by a differential attack with $6+\lceil\log_L(MN)\rceil$ chosen-

Biclique Cryptanalysis on the Full Crypton-256 and mCrypton-128
Journal of Applied Mathematics, 2014 Biclique cryptanalysis is an attack which reduces the computational complexity by finding a biclique which is a kind of bipartite graph. We show a single-key full-round attack of the Crypton-256 and mCrypton-128 by using biclique cryptanalysis.
