Universal hashing

Introduction to Coding Theory, 2018
Using universal hashing (in a randomized algorithm or data structure) refers to selecting a hash function at random from a family of hash functions with a certain mathematical property (see definition below). This guarantees a low number of collisions in

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.

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.
