We present preimage attacks on the SHA-3 candidates Boole, EnRUPT, Edon-R, and
Sarmal, which are found to be vulnerable against a meet-in-the-middle attack. The idea is to …

We present a new statistical cryptanalytic technique that we call improbable differential
cryptanalysis which uses a differential that is less probable when the correct key is used. We …

Cryptographic primitives are the basic building blocks of various cryptographic systems and
protocols. Their application is based on their well established properties. The security of a …

This paper gives a rough classification of various AES-based hash algorithms that have
been accepted for Round 1 of the NIST Hash Function Competition. We compare the …

The traditional method for describing cryptographic hash algorithms is to offer two
components: the compression function and an iteration scheme. This paper shows that …
