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 ...

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.

Low-Complexity Cryptographic Hash Functions
8th Innovations in Theoretical Computer Science Conference (ITCS 2017), 2017 Cryptographic hash functions are efficiently computable functions that shrink a long input into a shorter output while achieving some of the useful security properties of a random function. The most common type of such hash functions is collision resistant hash functions (CRH), which prevent an efficient attacker from finding a pair of inputs on which ...
