Hyperdimensional hashing

Proceedings of the 59th ACM/IEEE Design Automation Conference, 2022
Most cloud services and distributed applications rely on hashing algorithms that allow dynamic scaling of a robust and efficient hash table. Examples include AWS, Google Cloud and BitTorrent. Consistent and rendezvous hashing are algorithms that minimize key remapping as the hash table resizes.

Image Encryption Based on Hash Table Scrambling and DNA Substitution

IEEE Access, 2020
This paper proposes an image encryption algorithm based on hash table structure scrambling and DNA substitution. The algorithm uses the classical `scrambling-diffusion' process, and the pseudo-random sequence used in each process is generated by the ...

Better GPU Hash Tables

CoRR, 2021
We revisit the problem of building static hash tables on the GPU and design and build three bucketed hash tables that use different probing schemes. Our implementations are lock-free and offer efficient memory access patterns; thus, only the probing scheme is the factor affecting the performance of the hash table's different operations.

Trigonometric words ranking model for spam message classification

IET Networks, EarlyView., 2022
Abstract The significant increase in the volume of fake (spam) messages has led to an urgent need to develop and implement a robust anti‐spam method. Several of the current anti‐spam systems depend mainly on the word order of the message in determining the spam message, which results in the system's inability to predict the correct type of message when
