A Hash-Based Quantum-Resistant Chameleon Signature Scheme
Sensors, 2021 As a standard digital signature may be verified by anybody, it is unsuitable for personal or economically sensitive applications. The chameleon signature system was presented by Krawczyk and Rabin as a solution to this problem. It is based on a hash then

Quantum Security of Hash Functions and Property-Preservation of Iterated Hashing [PDF]
, 2019 This work contains two major parts: comprehensively studying the security notions of cryptographic hash functions against quantum attacks and the relationships between them; and revisiting whether Merkle-Damgard and related iterated hash constructions preserve the security properties of the compression function in the quantum setting.

Parametric Hash Function Resistant to Attack by Quantum Computer [PDF]
Annals of Computer Science and Information Systems, 2018 This paper describes an algorithm for creating hash function, resistant for quantum computer. The given approach is based on the problem of solving a system of polynomial equations in integers, where the number of equations is less than the number of unknown parameters. The developed algorithm is parameterized so the result of the hash function depends

Digital signatures over HMAC entangled chains
Engineering Science and Technology, an International Journal, 2022 In this work we present a new digital signature method based on hash chains and the hash message authentication code (HMAC). Unlike Blockchain technology, our approach establishes that the database of transactions is distributed among users, so each one ...
