Energy Scalable Universal Hashing

IEEE Transactions on Computers, 2005
Message authentication codes (MACs) are valuable tools for ensuring the integrity of messages. MACs may be built around a universal hash function (NH) which was explored in the construction of UMAC. In this paper, we use a variation on NH called WH. WH reaches optimally in the sense that it is universal with half the hash length of NH and it achieves ...

FUZZY UNIVERSAL HASHING AND APPROXIMATE AUTHENTICATION

Discrete Mathematics, Algorithms and Applications, 2011
Traditional data authentication systems are sensitive to single bit changes and so are unsuitable for message spaces that are naturally "fuzzy" where "similar" messages are considered "the same" or indistinguishable. In this paper, we study unconditionally secure approximate authentication.

Quantum Hashing via Classical $��$-universal Hashing Constructions

2014
In the paper, we define the concept of the quantum hash generator and offer design, which allows to build a large amount of different quantum hash functions. The construction is based on composition of classical $ $-universal hash family and a given family of functions -- quantum hash generator.

Universal Hashing and Geometric Codes

Designs, Codes and Cryptography, 1997
A universal class of hash functions is, grosso modo, a collection of hash functions such that a random choice of a function in the set yields a low probability that any two distinct inputs will collide. The concept is due to Carter and Wegman, and has numerous applications. (See the introduction to [\textit{D. R.

Hashing practice: analysis of hashing and universal hashing

ACM SIGMOD Record, 1988
Much of the literature on hashing deals with overflow handling (collision resolution) techniques and its analysis. What does all the analytical results mean in practice and how can they be achieved with practical files? This paper considers the problem of achieving analytical performance of hashing techniques in practice with reference to successful ...
