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

SPHINCS$^+$ post-quantum digital signature scheme with Streebog hash function
, 2020 Many commonly used public key cryptosystems will become insecure once a scalable quantum computer is built. New cryptographic schemes that can guarantee protection against attacks with quantum computers, so-called post-quantum algorithms, have emerged in

More Efficient Privacy Amplification with Less Random Seeds via Dual Universal Hash Function
, 2015 We explicitly construct random hash functions for privacy amplification (extractors) that require smaller random seed lengths than the previous literature, and still allow efficient implementations with complexity $O(n\log n)$ for input length $n$.

Exploring Nanoengineered Manganese Oxide‐Based Composite Catalysts for Acidic Water Electrooxidation
ChemElectroChem, EarlyView.Au NWs incorporated with MnOx serve dual roles: enhancing catalyst layer conductivity to improve Mn utilization and modulating Mn oxidation states to stabilize Mn3+, boosting oxygen evolution reaction activity and durability. Optimal performance depends on the MnOx/Au ratio, as demonstrated by the composite 5Mn + 1Au. Developing efficient, acid‐stable,

Spinal code based on lightweight hash function [PDF]
Archives of Electrical Engineering, 2019 A spinal code is the type of rateless code, which has been proved to be capacity- achieving over both a binary symmetric channel (BSC) and an additive white Gaussian noise (AWGN) channel. Rateless spinal codes employ a hash function as a coding kernel to

Learning to Hash-tag Videos with Tag2Vec
, 2016 User-given tags or labels are valuable resources for semantic understanding of visual media such as images and videos. Recently, a new type of labeling mechanism known as hash-tags have become increasingly popular on social media sites. In this paper, we

Annales UMCS, Informatica, 2012 In this paper we describe a family of highly parameterized hash functions. This parameterization results in great flexibility between performance and security of the algorithm. The three basic functions, HaF-256, HaF-512 and HaF-1024 constitute this hash function family. Lengths of message digests are 256, 512 and 1024 bits respectively.

Civil Engineering Design, Volume 7, Issue 1, Page 9-22, March 2025.Abstract Blockchain technology is a digital decentralized data ledger recording transactions in an encrypted format. Its implementation can potentially hold significant advantages for the built environment, particularly in manufacturing and building product usage aligned with Building Information Modeling (BIM). This paradigm shift toward decentralized

Asymmetric Deep Supervised Hashing
, 2017 Hashing has been widely used for large-scale approximate nearest neighbor search because of its storage and search efficiency. Recent work has found that deep supervised hashing can significantly outperform non-deep supervised hashing in many ...
