QKD parameter estimation by two-universal hashing [PDF]
This paper proposes and proves security of a QKD protocol which uses two-universal hashing instead of random sampling to estimate the number of bit flip and phase flip errors.

Multimixer-128: Universal Keyed Hashing Based on Integer Multiplication
In this paper we introduce a new keyed hash function based on 32-bit integer multiplication that we call Multimixer-128. In our approach, we follow the key-then-hash parallel paradigm. So, we first add a variable length input message to a secret key and

Universal Hashing and Multiple Authentication [PDF]
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.

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 ...

Variationally universal hashing [PDF]
The strongest well-known measure for the quality of a universal hash-function family H is its being e-strongly universal, which measures, for randomly chosen h ∈ H, one's inability to guess h(m') even if h(m) is known for some m ≠ m' We give example applications in which this measure is too weak, and we introduce a stronger measure for the quality of a

Explicit Orthogonal Arrays and Universal Hashing with Arbitrary Parameters [PDF]
Orthogonal arrays are a type of combinatorial design that emerged in the 1940s in the design of statistical experiments. In 1947, Rao proved a lower bound on the size of any orthogonal array, and raised the problem of constructing arrays of minimum size.

Construction of universal one-way hash functions: Tree hashing revisited
AbstractWe present a binary tree based parallel algorithm for extending the domain of a universal one-way hash function (UOWHF). For t⩾2, our algorithm extends the domain from the set of all n-bit strings to the set of all ((2t-1)(n-m)+m)-bit strings, where m is the length of the message digest. The associated increase in key length is 2m bits for t=2;
