Compression Function Design Principles Supporting Variable Output Lengths from a Single Small Function
In this paper, we introduce new compression function design principles supporting variable output lengths (multiples of size n). They are based on a function or block cipher with a...

Quasi-Pipelined Hash Circuits
Hash functions are an important cryptographic primitive. They are used to obtain a fixed-size fingerprint, or hash value, of an arbitrary long message. We focus particularly on ...

Hash Function Balance and Its Impact on Birthday Attacks
Textbooks tell us that a birthday attack on a hash function h with range size r requires r1/2 trials (hash computations) to find a collision. But this is quite misleading, being t...

spongent: A Lightweight Hash Function
This paper proposes spongent – a family of lightweight hash functions with hash sizes of 88 (for preimage resistance only), 128, 160, 224, and 256 bits based on a sponge construc...

Structural Attacks on Two SHA-3 Candidates: Blender-n and DCH-n
The recently started SHA-3 competition in order to find a new secure hash standard and thus a replacement for SHA-1/SHA-2 has attracted a lot of interest in the academic world as ...
