Evaluation of password hashing competition finalists: performance, security, compliance mapping, and post-quantum readiness

Password hashes and key derivation functions (KDFs) are central to authentication and cryptographic security schemes crafted to defend user credentials from brute-force attacks and unauthorized access.

Quantum Hashing. Group approach

, 2020
© 2016, Pleiades Publishing, Ltd.In this paper we consider a generalization of quantum hash functions for arbitrary groups. We show that quantum hash function exists for arbitrary abelian group.

Fault-tolerant quantum memory using low-depth random circuit codes

Physical Review Research
Low-depth random circuit codes possess many desirable properties for quantum error correction but have so far only been analyzed in the code capacity setting where it is assumed that encoding gates and syndrome measurements are noiseless.

Cryptographic quantum hashing

, 2020
We present a version of quantum hash functions based on non-binary discrete functions. The proposed quantum procedure is 'classical-quantum', that is, it takes a classical bit string as an input and produces a quantum state.

On the balanced quantum hashing

, 2020
In the paper we define a notion of a resistant quantum hash function which combines a notion of pre-image (one-way) resistance and the notion of collision resistance.
