Universal Hashing and Geometric Codes [PDF]

open access: yesDesigns, 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.

Universal Hashing and Multiple Authentication [PDF]

open access: yes, 1996
In this paper, we study unconditionally secure codes that provide authentication without secrecy. Our point of view is the universal hashing approach pioneered by Wegman and Carter in 1981. We first compare several recent universal-hashing based constructions for authentication codes.

Strongly Universal String Hashing is Fast [PDF]

open access: yesThe Computer Journal, 2013
We present fast strongly universal string hashing families: they can process data at a rate of 0.2 CPU cycle per byte. Maybe surprisingly, we find that these families---though they require a large buffer of random numbers---are often faster than popular hash functions with weaker theoretical guarantees.

On Risks of Using Cuckoo Hashing with Simple Universal Hash Classes [PDF]

open access: yesProceedings of the Twentieth Annual ACM-SIAM Symposium on Discrete Algorithms, 2009
Cuckoo hashing, introduced by Pagh and Rodler [10], is a dynamic dictionary data structure for storing a set S of n keys from a universe U, with constant lookup time and amortized expected constant insertion time.

The Message Authentication Code Based on Universal Hashing [PDF]

open access: yesБезопасность информационных технологий, 2012
The article covers the research of message authentication codes based on universal hashing. The new message authentication code algorithm is described here. The analysis of the algorithm is also provided in this article.

Software Performance of Universal Hash Functions [PDF]

open access: yes, 1999
This paper compares the parameters sizes and software performance of several recent constructions for universal hash functions: bucket hashing, polynomial hashing, Toeplitz hashing, division hashing, evaluation hashing, and MMH hashing. An objective comparison between these widely varying approaches is achieved by defining constructions that offer a ...

Invertible Universal Hashing and the TET Encryption Mode [PDF]

open access: yes, 2007
This work describes a mode of operation, TET, that turns a regular block cipher into a length-preserving enciphering scheme for messages of (almost) arbitrary length. When using an n-bit block cipher, the resulting scheme can handle input of any bit-length between n and 2n and associated data of arbitrary length.

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

open access: yesSoftware: Practice and Experience, 2016
SummaryRandom 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 same hash value is low given that we pick hash functions at random. However, universality fails
