Attacking Quantum Hashing. Protocols and Their Cryptanalysis

Abstract

© 2018, Pleiades Publishing, Ltd. Quantumhash functions are similar to classical (cryptographic) hash functions and their security is guaranteed by physical laws. However, security of a primitive does not automatically mean that protocols based on this primitive are secure. We propose protocols based on quantum hash function and assess their security using Holevo entropy and recently introduced notion of quantum information cost.
