The Usefulness of Multilevel Hash Tables with Multiple Hash Functions in Large Databases [PDF]
Anale: Seria Informatică, 2009 In this work, attempt is made to select three good hash functions which uniformly distribute hash values that permute their internal states and allow the input bits to generate different output bits.

A Novel Hash Function Based on a Chaotic Sponge and DNA Sequence
IEEE Access, 2021 Many chaos-based hash functions have convoluted designs that are not based on proper design principles, complicating the verification of security claims.

A New Hash Function Based on Chaotic Maps and Deterministic Finite State Automata
IEEE Access, 2020 In this paper, a new chaos-based hash function is proposed based on a recently proposed structure known as the deterministic chaotic finite state automata (DCFSA). Out of its various configurations, we select the forward and parameter permutation variant,

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.

Finding Bugs in Cryptographic Hash Function Implementations. [PDF]
IEEE Trans Reliab, 2018 Cryptographic hash functions are security-critical algorithms with many practical applications, notably in digital signatures. Developing an approach to test them can be particularly difficult, and bugs can remain unnoticed for many years. We revisit the

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 ...

Keyed Hash Function Using Hyper Chaotic System With Time-Varying Parameters Perturbation
IEEE Access, 2019 Secure hash function plays an important role in cryptography. This paper constructs a hash algorithm using the hyperchaotic Lorenz system, which serves as a sponge function to absorb input message via multiple parameters time-varying perturbation. First,

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.
