Design and Analysis of Multi-Block-Length Hash Functions

Cryptographic hash functions are used in many cryptographic applications, and the design of provably secure hash functions (relative to various security notions) is an active area of research. Most of the currently existing hash functions use the Merkle-Da ...

Efficient Hashing Using the AES Instruction Set

Joppe Willem Bos, Martijn Stam, Onur Özen

In this work, we provide a software benchmark for a large range of 256-bit blockcipher-based hash functions. We instantiate the underlying blockcipher with AES, which allows us to exploit the recent AES instruction set (AESNI). Since AES itself only output ...

Another Glance at Double-Length Hashing

Martijn Stam, Onur Özen

We propose a novel framework for blockcipher-based double-length hash functions by extending the recent generalization presented by Stam at FSE '09 for single-call hash functions. We focus on compression functions compressing 3n bits to 2n bits that use on ...
