Challenging the increased resistance of regular hash functions against birthday attacks
Journal of Mathematical Cryptology, 2012 At Eurocrypt 2004, Bellare and Kohno presented the concept of a regular hash function. For a hash function to be regular, every hash value must have the same number of preimages in the domain.

From Graphs to Keyed Quantum Hash Functions [PDF]
, 2016 We present two new constructions of quantum hash functions: the first based on expander graphs and the second based on extractor functions and estimate the amount of randomness that is needed to construct them.

Hash functions for priority queues
24th Annual Symposium on Foundations of Computer Science (sfcs 1983), 1983 The complexity of priority queue operations is analyzed with respect to the cell probe computational model of A. Yao (J. Assoc. Comput. Mach. 28, No. 3 (1981), 615–628). A method utilizing families of hash functions is developed which permits priority queue operations to be implemented in constant worst-case time provided that a size constraint is ...

Regular and almost universal hashing: an efficient implementation [PDF]
, 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 ...

EliMAC: Speeding Up LightMAC by around 20%
IACR Transactions on Symmetric Cryptology, 2023 Universal hash functions play a prominent role in the design of message authentication codes and the like. Whereas it is known how to build highly efficient sequential universal hash functions, parallel non-algebraic universal hash function designs are ...
