From graphs to keyed quantum hash functions
Lobachevskii Journal of Mathematics, 2016 We present two new constructions of quantum hash functions: the first based on expander graphs and the second based on extractor functions and estimate the amount of randomness that is needed to construct them. We also propose a keyed quantum hash function based on extractor function that can be used in quantum message authentication codes and assess ...

Automated quantum circuit generation for computing inverse hash functions
Quantum Information Science, Sensing, and Computation XVISeveral cryptographic systems depend upon the computational difficulty of reversing cryptographic hash functions. Robust hash functions transform inputs to outputs in such a way that the inputs cannot be later retrieved in a reasonable amount of time even if the outputs and the function that created them are known.

Quantum search for scaled hash function preimages [PDF]
Quantum Information Processing, 2021 AbstractWe present the implementation of Grover’s algorithm in a quantum simulator to perform a quantum search for preimages of two scaled hash functions, whose design only uses modular addition, word rotation and bitwise exclusive or. Our implementation provides the means to assess with precision the scaling of the number of gates and depth of a full ...

Hash Function Based on Controlled Alternate Quantum Walks With Memory (September 2021)
IEEE Transactions on Quantum Engineering, 2022 We propose a Quantum inspired Hash Function using controlled alternate quantum walks with Memory on cycles (QHFM), where the $j$th message bit decides whether to run quantum walk with one-step memory or to run quantum walk with two-step memory at the $j ...
