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

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
