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.

High Performance Construction of RecSplit Based Minimal Perfect Hash Functions [PDF]
, 2023 A minimal perfect hash function (MPHF) bijectively maps a set S of objects to the first |S| integers. It can be used as a building block in databases and data compression.

XOR Chain and Perfect Secrecy at the Dawn of the Quantum Era
Cryptography, 2023 In this article, we present a new method that achieves Shannon’s perfect secrecy. To achieve this property, we will introduce the triple XOR cancellation rule. The approach has two execution modes: digital signature and data encryption.

General encoding of canonical k-mers
Peer Community Journal, 2023 To index or compare sequences efficiently, often k-mers, i.e., substrings of fixed length k, are used. For efficient indexing or storage, k-mers are often encoded as integers, e.g., applying some bijective mapping between all possible σk k-mers and the ...

Secure Authentication in the Smart Grid
Mathematics, 2022 Authenticated key agreement is a process in which protocol participants communicate over a public channel to share a secret session key, which is then used to encrypt data transferred in subsequent communications.

Accelerating Minimal Perfect Hash Function Construction Using GPU Parallelization [PDF]
, 2023 Eine Minimale Perfekte Hashfunktion (MPHF) bildet eine Menge von N Schlüsseln kollisionsfrei auf die Menge [N ] := {0, .., N − 1} ab. Diese Thesis leistet einen signifikanten Beitrag für den folgenden generischen MPHF Konstruktionsalgorithmus.

MOVE GENERATION WITH PERFECT HASH FUNCTIONS [PDF]
ICGA Journal, 2008 We present two new perfect hashing schemes that can be used for efficient bitboard move generation for sliding pieces in chess-like board games without the need to use rotated bitboards. Moreover, we show that simple variations of these schemes give minimal perfect hashing schemes.
