Fast Scalable Construction of (Minimal Perfect Hash) Functions [PDF]
, 2016 Recent advances in random linear systems on finite fields have paved the way for the construction of constant-time data structures representing static functions and minimal perfect hash functions using less space with respect to existing techniques.

Balanced Families of Perfect Hash Functions and Their Applications [PDF]
, 2008 The construction of perfect hash functions is a well-studied topic. In this paper, this concept is generalized with the following definition. We say that a family of functions from $[n]$ to $[k]$ is a $\delta$-balanced $(n,k)$-family of perfect hash ...

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.

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 ...
