+ | abstract = {Bernstein’s CubeHash is a hash function family that includes four functions submitted to the NIST Hash Competition. A CubeHash function is parametrized by a number of rounds r, a block byte size b, and a digest bit length h. The 1024-bit internal state of CubeHash is represented as a five-dimension hypercube. Submissions to NIST have r = 8, b = 1, and $h \in {224, 256, 384, 512}$. | ||
+ | This paper gives the first external analysis of CubeHash, with | ||
+ | - improved standard generic attacks for collisions and preimages | ||
+ | - a multicollision attack that exploits fixed points | ||
+ | - a study of the round function symmetries | ||
+ | - a preimage attack that exploits these symmetries | ||
+ | - a practical collision attack on a weakened version of CubeHash | ||
+ | - high-probability truncated differentials over the 8-round transform | ||
+ | Our results do not contradict the security claims about CubeHash.}, | ||
