Bottom-k and Priority Sampling, Set Similarity and Subset Sums with Minimal Independence [PDF]
, 2013 We consider bottom-k sampling for a set X, picking a sample S_k(X) consisting of the k elements that are smallest according to a given hash function h. With this sample we can estimate the relative size f=|Y|/|X| of any subset Y as |S_k(X) intersect Y|/k.

Efficient computation of hashes [PDF]
, 2014 The sequential computation of hashes at the core of many distributed storage systems and found, for example, in grid services can hinder efficiency in service quality and even pose security challenges that can only be addressed by the use of parallel ...

Cryptographic Hash Functions: [PDF]
IEICE ESS Fundamentals Review, 2010 Cryptographic hash functions are an important tool of cryptography and play a fundamental role in efficient and secure information processing. A hash function processes an arbitrary finite length input message to a fixed length output referred to as the hash value.

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.
