An Improved Hash Function Based on the Tillich-Zémor Hash Function [PDF]
Mathematics Interdisciplinary Research, 2018 Using the idea behind the Tillich-Zémor hash function, we propose a new hash function. Our hash function is parallelizable and its collision resistance is implied by a hardness assumption on a mathematical problem.

A Hash of Hash Functions [PDF]
arXiv, 2003 In this paper, we present a general review of hash functions in a cryptographic sense. We give special emphasis on some particular topics such as cipher block chaining message authentication code (CBC MAC) and its variants. This paper also broadens the information given in some well known surveys, by including more details on block-cipher based hash ...

The Grindahl Hash Functions [PDF]
, 2007 In this paper we propose the Grindahl hash functions, which are based on components of the Rijndael algorithm. To make collision search sufficiently difficult, this design has the important feature that no low-weight characteristics form collisions, and at the same time it limits access to the state.

Programmable Hash Functions and Their Applications [PDF]
Journal of Cryptology, 2008 We introduce a new information-theoretic primitive called programmable hash functions(PHFs). PHFs can be used to programthe output of a hash function such that it contains solved or unsolved discrete logarithm instances with a certain probability. This is a technique originally used for security proofs in the random oracle model.

New hash function based on C-MD structure and chaotic neural network
网络与信息安全学报, 2023 In recent years, widely used hash algorithms such as MD5 and SHA-1 have been found to have varying degrees of security risks.The iterative structure of the SHA-2 algorithm is similar to that of SHA-1, making it vulnerable to attacks as well.Meanwhile ...
