Internal Distinguishers in Indifferentiable Hashing: The Shabal Case

We show the first indifferentiability proof of a hash construction C ^F which does not make the assumption that the inner primitive F is ideal, but allows the existence (up to certain bounds that we explicit) of statistical distinguishers on F. Read the rest of this entry »

Unfolding Method for Shabal on Virtex-5 FPGAs: Concrete Results

In this paper, we focus on an optimized implementation of the Shabal candidate. We improve the state-of-the-art using the unfolding method. Read the rest of this entry »
