Asymptotic Analysis of Plausible Tree Hash Modes for SHA-3
Kevin Atighehchi, Alexis Bonnecaze
Discussions about the choice of a tree hash mode of operation for a standardization have recently been undertaken. It appears that a single tree mode cannot address adequately all…

Some observations on the optimization of a parallel SHAKE function using Sakura
Kevin Atighehchi
Some parallel constructions of a SHAKE hash function using Sakura coding are introduced, whose basic operation is the Keccak's permutation. For each proposed tree-based algorithm,…

On the Incremental Asymmetric Signatures
Kevin Atighehchi
The purpose of incremental cryptography is to allow the updating of cryptographic forms of documents undergoing modifications, more efficiently than if we had to recompute them fro…
