Strongly universal string hashing is fast [PDF]

The Computer Journal, 2014
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 ...

Multimixer-128: Universal Keyed Hashing Based on Integer Multiplication

IACR Transactions on Symmetric Cryptology, 2023
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

QKD parameter estimation by two-universal hashing [PDF]

Quantum, 2023
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.

Chip-integrated quantum signature network over 200 km [PDF]

Light: Science & Applications
The development of quantum networks is paramount towards practical and secure communications. Quantum digital signatures (QDS) offer an information-theoretically secure solution for ensuring data integrity, authenticity, and non-repudiation, rapidly ...

Universal hash functions from quantum procedures

Учёные записки Казанского университета: Серия Физико-математические науки, 2020
Modern quantum technologies are NISQ (Noisy Intermediate-Scale Quantum) devices, which are used to create insufficiently accurate quantum computers with low computing power.

A Fast Single-Key Two-Level Universal Hash Function

IACR Transactions on Symmetric Cryptology, 2017
Universal hash functions based on univariate polynomials are well known, e.g. Poly1305 and GHASH. Using Horner’s rule to evaluate such hash functionsrequire l − 1 field multiplications for hashing a message consisting of l blocks where each block is one ...

Comprehensive Performance Study of Hashing Functions [PDF]

Computer Science Journal of Moldova, 2023
Most literature on hashing functions speaks in terms of hashing functions being either ‘good’ or ‘bad’. In this paper, we demonstrate how a hashing function that gives good results for one key set, performs badly for another.

EliMAC: Speeding Up LightMAC by around 20%

IACR Transactions on Symmetric Cryptology, 2023
Universal hash functions play a prominent role in the design of message authentication codes and the like. Whereas it is known how to build highly efficient sequential universal hash functions, parallel non-algebraic universal hash function designs are ...

EXTENSION OF SSL/TLS FOR QUANTUM CRYPTOGRAPHY [PDF]

مجلة جامعة الانبار للعلوم الصرفة, 2008
SSL/TLS is the protocol that is used for the vast majority of secure transactions over the Internet. However, this protocol needs to be extended in order to create a promising platform for the integration of quantum cryptography (QC) into the Internet ...
