Performance Analysis of Cryptographic Hash Functions Suitable for Use in Blockchain
International Journal of Computer Network and Information Security, 2021 A blockchain, or in other words a chain of transaction blocks, is a distributed database that maintains an ordered chain of blocks that reliably connect the information contained in them.

The Random Oracle Methodology, Revisited [PDF]
, 2000 We take a critical look at the relationship between the security of cryptographic schemes in the Random Oracle Model, and the security of the schemes that result from implementing the random oracle by so called "cryptographic hash functions".

Quantum security of hash functions and property-preservation of iterated hashing [PDF]
Post-Quantum Cryptography, 2019 This work contains two major parts: comprehensively studying the security notions of cryptographic hash functions against quantum attacks and the relationships between them; and revisiting whether Merkle-Damgard and related iterated hash constructions ...

On the Design of Provably-Secure Cryptographic Hash Functions [PDF]
, 1991 Recently, formal complexity-theoretic treatment of cryptographic hash functions was suggested. Two primitives of Collision-free hash functions and Universal one-way hash function families have been defined. The primitives have numerous applications in secure information compression, since their security implies that finding collisions is ...
