Estimating the cost of generic quantum pre-image attacks on SHA-2 and SHA-3 [PDF]

open access: greenarXiv, 2016
We investigate the cost of Grover's quantum search algorithm when used in the context of pre-image attacks on the SHA-2 and SHA-3 families of hash functions. Our cost model assumes that the attack is run on a surface code based fault-tolerant quantum computer.

Time-Space Complexity of Quantum Search Algorithms in Symmetric Cryptanalysis [PDF]

open access: hybridQuantum Inf Process (2018) 17: 339, 2018
Performance of cryptanalytic quantum search algorithms is mainly inferred from query complexity which hides overhead induced by an implementation. To shed light on quantitative complexity analysis removing hidden factors, we provide a framework for estimating time-space complexity, with carefully accounting for characteristics of target cryptographic ...

Carry-based Differential Power Analysis (CDPA) and its Application to Attacking HMAC-SHA-2

open access: diamondTransactions on Cryptographic Hardware and Embedded Systems, 2023
In this paper, we introduce Carry-based Differential Power Analysis (CDPA), a novel methodology that allows for attacking schemes that use arithmetical addition. We apply this methodology to attacking HMAC-SHA-2.

Applying Grover's Algorithm to Hash Functions: A Software Perspective [PDF]

open access: yesIEEE Transactions on Quantum Engineering, 2022
Quantum software frameworks provide software engineers with the tools to study quantum algorithms as applied to practical problems. We implement classical hash functions MD5, SHA-1, SHA-2, and SHA-3 as quantum oracles to study the computational resource requirements of conducting a preimage attack with Grover's Algorithm. We introduce an improvement to
