Regular and almost universal hashing: an efficient implementation [PDF]
Random hashing can provide guarantees regarding the performance of data structures such as hash tables---even in an adversarial setting. Many existing families of hash functions are universal: given two data objects, the probability that they have the ...

The purpose of this article is to construct an internal function underlying the “Sponge” scheme for constructing cryptographic hash functions. An internal function in the “Sponge” scheme is a fixed-length transformation or permutation that

SPHINCS$^+$ post-quantum digital signature scheme with Streebog hash function
Many commonly used public key cryptosystems will become insecure once a scalable quantum computer is built. New cryptographic schemes that can guarantee protection against attacks with quantum computers, so-called post-quantum algorithms, have emerged in

Security of a New Cryptographic Hash Function - Titanium [PDF]
This paper introduces the security analysis of Titanium hash function that uses SF block cipher and follows sponge construction. A brief description of the sponge function and the design choice of Titanium are introduced. Basic security criteria of random function have been presented and studied on Titanium and then, differential cryptanalysis on ...

Construction and Analysis of SHA-256 Compression Function Based on Chaos S-Box
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 ...

Cryptographic Hash Function using Cellular Automata [PDF]
Since two distinct messages are extremely unlikely to generate identical message digests, one can use this property of cryptographic hash functions to detect when a message has been altered. If one takes a binary file and computes a digest of the file, one can record this baseline digest. In the future, the digest can be recomputed on the file.
