Bad Directions in Cryptographic Hash Functions
, 2015 A 25-gigabyte “point obfuscation” challenge “using security parameter 60” was announced at the Crypto 2014 rump session; “point obfuscation” is another name for password hashing. This paper shows that the particular matrix-multiplication hash function used in the challenge is much less secure than previous password-hashing functions are believed to be.

A Cryptographic Hash Function from Markoff Triples
IACR Cryptol. ePrint Arch., 2021 Cryptographic hash functions from expander graphs were proposed by Charles, Goren, and Lauter in [CGL] based on the hardness of finding paths in the graph. In this paper, we propose a new candidate for a hash function based on the hardness of finding paths in the graph of Markoff triples modulo p.

ON THE UNIVERSAL TREE MODE OF HASH CODE GENERATION
Современные информационные технологии и IT-образование, 2018 Classical approaches to the construction of hash function modes, based on the using of iterative procedures, do not allow efficient processing of large amounts of data and can’t be adapted to parallel computing architectures.

Construction and Analysis of SHA-256 Compression Function Based on Chaos S-Box
IEEE Access, 2021 To further improve the security of SHA-256, a compression function construction scheme based on chaotic S-box is proposed. Through the reasonable design of the iteration mode and using the nonlinearity, confusion, and anti-difference of chaotic S-box ...
