Finding Bugs in Cryptographic Hash Function Implementations. [PDF]
IEEE Trans Reliab, 2018 Cryptographic hash functions are security-critical algorithms with many practical applications, notably in digital signatures. Developing an approach to test them can be particularly difficult, and bugs can remain unnoticed for many years. We revisit the NIST hash function competition, which was used to develop the SHA-3 standard, and apply a new ...

Low-Complexity Cryptographic Hash Functions
8th Innovations in Theoretical Computer Science Conference (ITCS 2017), 2017 Cryptographic hash functions are efficiently computable functions that shrink a long input into a shorter output while achieving some of the useful security properties of a random function. The most common type of such hash functions is collision resistant hash functions (CRH), which prevent an efficient attacker from finding a pair of inputs on which ...

Building Secure and Fast Cryptographic Hash Functions Using Programmable Cellular Automata [PDF]
, 2015 This paper presents a new hash function design, which is different from the popular designs of the MD4-family. Seen in the light of recent attacks on MD4, MD5, SHA-0, SHA-1, and on RIPEMD, there is a need to consider other hash function design strategies. The paper presents also a concrete hash function design named SMASH.
