A new method to solve MRHS equation systems and its connection to group factorization
Journal of Mathematical Cryptology, 2013 Multiple right-hand side (MRHS) equations over finite fields are a relatively new tool useful for algebraic cryptanalysis. The main advantage is in an efficient representation of the cryptographic primitives.

Cryptanalysis of Algebraic Verifiable Delay Functions
Verifiable Delay Functions (VDF) are a class of cryptographic primitives aiming to guarantee a minimum computation time, even for an adversary with massive parallel computational power. They are useful in blockchain protocols, and several practical candidates have been proposed based on exponentiation in a large finite field: Sloth++, Veedo, MinRoot ...

Algebraic Cryptanalysis of 58-Round SHA-1 [PDF]
, 2007 In 2004, a new attack against SHA-1 has been proposed by a team leaded by Wang [15]. The aim of this article is to sophisticate and improve Wang’s attack by using algebraic techniques. We introduce new notions, namely semi-neutral bit and adjuster and propose then an improved message modification technique based on algebraic techniques.

Tamper Localisation Using Quantum Fourier Transform Signatures for Medical Image Authentication
IET Quantum Communication, Volume 6, Issue 1, January/December 2025.We present a tamper‐localisation framework that embeds authentication signatures as phase‐only perturbations in blockwise QFT coefficients using keyed sparse mid‐band supports and light cross‐block coupling, preserving magnitudes (energy) and imperceptibility.

Algebraic Cryptanalysis of Ascon Using MRHS Equations
Tatra Mountains Mathematical PublicationsAbstract Ascon is a family of lightweight authenticated encryption and hashing algorithms, which is a finalist in the NIST Lightweight Cryptography competition. We study the Ascon algorithm from the perspective of algebraic cryptanalysis based on the MRHS representation of the cipher. We call such an approach an MRHS cryptanalysis.

A Novel Method of Data Protection Through DNA Chromosome Databases
Applied Computational Intelligence and Soft Computing, Volume 2025, Issue 1, 2025.With the advancement of the digital age, data have become insecure, which requires techniques to secure data. Deoxyribonucleic acid (DNA) has become an increasingly secure technology for storing next‐generation digital data. DNA provides superior capabilities due to its high and efficient storage capacity and long lifespan.
