five remaining candidates of the com petition are BLAKE, Grøstl, JH, Keccak, and Skein. While the main focus has been on the algorithmic candidates, a side channel analysis has only been performed for BLAKE and Grøstl [4]. In this contribution we identify side channel vulnerabilities for JH-MAC, Keccak-MAC ...
Since the Keccak algorithm was selected by the US National Institute of Standards and Technology (NIST) as the standard hash algorithm for replacing the currently used SHA-2 algorithm in 2015, various optimization methods have been studied in parallel and hardware environments. However, in a software environment, the algorithm is much slower than the existing SHA-2 family ...

We will use the notation \(0^s\) to refer to the all-zero bit string of length s.In the figures, the numbers given next to every line represent the length of the corresponding bit string and \(\oplus \) is the bitwise eXclusive-OR (XOR) operation. The function f is a cryptographic permutation. It is easy to evaluate f and its inverse \(f^{-1}\), but the outputs should appear "random," so ...
