Cryptographic Hash Functions [PDF]
, 2010 Cryptographic hash functions are an important tool of cryptography and play a fundamental role in efficient and secure information processing. A hash function processes an arbitrary finite length input message to a fixed length output referred to as the hash value.

IOSR Journal of Mathematics, 2013 We constructed a hash function by using the idea of cayley graph, hash function based on computing a suitable matrix product in groups of the form SL2(F2 n ). We found collision between palindrome bit strings of length 2n+2 for the new construction. Here we reinforce the hash function by adding key to it and we claim that it will resists palindrome ...

Perceptual Audio Hashing Functions [PDF]
EURASIP Journal on Advances in Signal Processing, 2005 Perceptual hash functions provide a tool for fast and reliable identification of content. We present new audio hash functions based on summarization of the time-frequency spectral characteristics of an audio document. The proposed hash functions are based on the periodicity series of the fundamental frequency and on singular-value description of the ...

Optimization of Tree Modes for Parallel Hash Functions: A Case Study [PDF]
, 2017 This paper focuses on parallel hash functions based on tree modes of operation for an inner Variable-Input-Length function. This inner function can be either a single-block-length (SBL) and prefix-free MD hash function, or a sponge-based hash function ...

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,

Multimixer-128: Universal Keyed Hashing Based on Integer Multiplication
IACR Transactions on Symmetric Cryptology, 2023 In this paper we introduce a new keyed hash function based on 32-bit integer multiplication that we call Multimixer-128. In our approach, we follow the key-then-hash parallel paradigm. So, we first add a variable length input message to a secret key and

A new hash function and its use in read mapping on genome [PDF]
AUT Journal of Mathematics and Computing, 2020 Mapping reads onto genomes is an indispensable step in sequencing data analysis. A widely used method to speed up mapping is to index a genome by a hash table, in which genomic positions of $k$-mers are stored in the table.
