Huge multicollisions and multipreimages of hash functions BLENDER-n（draft）
Huge multicollisions multipreimages of hash functions BLENDER-n
2009/6/11
In this paper we present a multicollision and multipreimage attack on the hash function Blender-n for all output sizes n = 224, 256, 384 and 512. The complexity and memory requirements for finding 22n...
Blender is a cryptographic hash function submitted to NIST’s SHA3 competition. We
have found a semi-free start collision attack on Blender with trivial complexity. One pair of
semi-free start collis...
