Optimization of Tree Modes for Parallel Hash Functions: A Case Study [PDF]
This paper focuses on parallel hash functions based on tree modes of operation for an inner Variable-Input-Length function. This inner function can be either a single-block-length (SBL) and prefix-free MD hash function, or a sponge-based hash function ...

Evolving hash functions by means of genetic programming [PDF]
Proceedings of the 8th annual conference on Genetic and evolutionary computation. Seattle, Washington, USA, July 08-12, 2006The design of hash functions by means of evolutionary computation is a relatively new and unexplored problem. In this work, we use

From Graphs to Keyed Quantum Hash Functions [PDF]
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.

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

Grayscale Image Authentication using Neural Hashing
Many different approaches for neural network based hash functions have been proposed. Statistical analysis must correlate security of them. This paper proposes novel neural hashing approach for gray scale image authentication.

A General Two-Step Approach to Learning-Based Hashing [PDF]
Most existing approaches to hashing apply a single form of hash function, and an optimization process which is typically deeply coupled to this specific form.

Efficient computation of hashes [PDF]
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 ...

Simple Tabulation, Fast Expanders, Double Tabulation, and High Independence
Simple tabulation dates back to Zobrist in 1970. Keys are viewed as c characters from some alphabet A. We initialize c tables h_0, ..., h_{c-1} mapping characters to random hash values.

Bottom-k and Priority Sampling, Set Similarity and Subset Sums with Minimal Independence [PDF]
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.
