Improving Data Integrity in Communication Systems by Designing a New Security Hash Algorithm [PDF]
, 2017 The objective of this paper is to design a new secure hash algorithm with final hash code length 512 bits. The proposed hash code algorithm based on the combination of SHA-256 algorithm -with modification in its message expansion- and MD5algorithm based ...

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

SL2 homomorphic hash functions: Worst case to average case reduction and short collision search [PDF]
, 2015 We study homomorphic hash functions into SL(2,q), the 2x2 matrices with determinant 1 over the field with $q$ elements. Modulo a well supported number theoretic hypothesis, which holds in particular for concrete homomorphisms proposed thus far, we ...

Hash-based signatures for the internet of things [PDF]
, 2018 While numerous digital signature schemes exist in the literature, most real-world system rely on RSA-based signature schemes or on the digital signature algorithm (DSA), including its elliptic curve cryptography variant ECDSA.

Enhancing the Security of MANETs using Hash Algorithms
Procedia Computer Science, 2015 AbstractHash functions are used in information security applications for the generation and verification of digital signatures, key derivation, and pseudorandom bit generation. Hash algorithms are secure because, for a given algorithm, it is computationally infeasible to find a message that corresponds to a given message digest, or to find two ...
