The First Collision for Full SHA-1 [PDF]
, 2017 SHA-1 is a widely used 1995 NIST cryptographic hash function standard that was officially deprecated by NIST in 2011 due to fundamental security weaknesses demonstrated in various analyses and theoretical attacks.

Freestart Collision for Full SHA-1 [PDF]
, 2016 This article presents an explicit freestart colliding pair for SHA-1, i.e. a collision for its internal compression function. This is the first practical break of the full SHA-1, reaching all 80 out of 80 steps. Only 10 days of computation on a 64-GPU cluster were necessary to perform this attack, for a runtime cost equivalent to approximately 2^{57.5}

Applying Grover's Algorithm to Hash Functions: A Software Perspective
IEEE 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 ...

SHA-1 and the Strict Avalanche Criterion [PDF]
2016 Information Security for South Africa (ISSA), 2016 The Strict Avalanche Criterion (SAC) is a measure of both confusion and diffusion, which are key properties of a cryptographic hash function. This work provides a working definition of the SAC, describes an experimental methodology that can be used to statistically evaluate whether a cryptographic hash meets the SAC, and uses this to investigate the ...
