A Tweak for a PRF Mode of a Compression Function and Its Applications
compression function MAC pseudorandom function
font style='font-size:12px;'>
2016/6/22
We discuss a tweak for the domain extension called Merkle-Damg錼d with Permutation (MDP), which was presented at ASIACRYPT 2007. We first show that MDP may produce multiple independent pseudorandom fun...
Provable Security of BLAKE with Non-Ideal Compression Function
secret-key cryptography / SHA-3 BLAKE collision resistance
