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

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