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.

low complexity cryptographic hash functions [PDF]
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

FPGA-Based Lightweight Hardware Architecture of the PHOTON Hash Function for IoT Edge Devices
IEEE Access, 2020 The design of cryptographic engines for the Internet of Things (IoT) edge devices and other ultralightweight devices is a crucial challenge. The emergence of such resource-constrained devices raises significant challenges to current cryptographic ...

Analysis of the amplitude form of the quantum hash function
Учёные записки Казанского университета: Серия Физико-математические науки, 2023 In this article, the properties of quantum hash functions are further explored. Previous findings show that so-called small-bias sets (special subsets of the set of elements of a cyclic group) generate a “phase” quantum hash function. Here, it was proved

A Family of Fast Syndrome Based Cryptographic Hash Functions [PDF]
, 2005 Recently, some collisions have been exposed for a variety of cryptographic hash functions~\cite{WFLY04} including some of the most widely used today. Many other hash functions using similar constrcutions can however still be considered secure. Nevertheless, this has drawn attention on the need for new hash function designs. In this article is presented

Cryptographic Hash Functions from Expander Graphs [PDF]
Journal of Cryptology, 2007 We propose constructing provable collision resistant hash functions from expander graphs in which finding cycles is hard. As examples, we investigate two specific families of optimal expander graphs for provable collision resistant hash function constructions: the families of Ramanujan graphs constructed by Lubotzky-Phillips-Sarnak and Pizer ...

Reversible and Plausibly Deniable Covert Channels in One-Time Passwords Based on Hash Chains
Applied Sciences, 2021 Covert channels enable stealthy communications over innocent appearing carriers. They are increasingly applied in the network context. However, little work is available that exploits cryptographic primitives in the networking context to establish such ...
