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

Adaptive Restart and CEGAR-based Solver for Inverting Cryptographic Hash Functions [PDF]
arXiv, 2016 SAT solvers are increasingly being used for cryptanalysis of hash functions and symmetric encryption schemes. Inspired by this trend, we present MapleCrypt which is a SAT solver-based cryptanalysis tool for inverting hash functions. We reduce the hash function inversion problem for fixed targets into the satisfiability problem for Boolean logic, and ...

Regular and almost universal hashing: an efficient implementation [PDF]
Software: Practice and Experience 47 (10), 2017, 2016 Random hashing can provide guarantees regarding the performance of data structures such as hash tables---even in an adversarial setting. Many existing families of hash functions are universal: given two data objects, the probability that they have the same hash value is low given that we pick hash functions at random.
