A Multichaotic Map Approach to Image Encryption and Security Analysis

Journal of Computer Networks and Communications, Volume 2026, Issue 1, 2026.
Encryption remains one of the most effective techniques for securing digital data. Over the years, researchers have explored many image encryption schemes to enhance the security of data. Existing cryptosystems still struggle to maintain an ultimate balance between efficiency, security, and resistance to attacks. Digital images contain highly sensitive

Polynomial Representations of Weak Inverse Property Quasigroups and Their Role in Cryptographic Primitives

Journal of Mathematics, Volume 2026, Issue 1, 2026.
A connection between cryptography and polynomial functions is extremely significant. Mathematical performance of polynomials helps to enhance the cryptographic primitives, which are trustworthy as well as straightforward representation tools, in everyday use. In this research, explicit topological sequences Qf which correspond to degree‐based, distance‐

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.

Preimage attacks on reduced‐round Keccak hash functions by solving algebraic systems

IET Information Security, 2023
In this paper, improved preimage attacks are presented on 3‐round Keccak‐256 and Keccak‐512 and 4‐round Keccak‐256 based on algebraic methods. The authors propose some new properties about the components of Keccak permutation, reconsider the existing ...

Permuting Generalized f‐Triderivations on Lattices

Journal of Mathematics, Volume 2026, Issue 1, 2026.
G. Szász initially proposed the idea of lattice derivation, and it has since been revived in the study of other problems in various branches of mathematics and applied sciences. The intention of the current research is to examine the structure of permuting generalized f‐triderivation linked with permuting f‐triderivation on lattice T,∧,∨ and to provide

Algebraic Techniques in Differential Cryptanalysis Revisited [PDF]

, 2011
At FSE 2009, Albrecht et al. proposed a new cryptanalytic method that combines algebraic and differential cryptanalysis. They introduced three new attacks, namely Attack A, Attack B and Attack C.

A Hybrid Matrix–Based Encoding Scheme With Error Detection via Third‐Order Recurrences

Journal of Mathematics, Volume 2026, Issue 1, 2026.
In this paper, we propose a novel encoding–decoding algorithm based on third‐order linear recurrence sequences and their associated matrix representations. In particular, third‐order Jacobsthal and third‐order Jacobsthal–Lucas matrix sequences are combined with Padovan and Perrin matrix sequences to construct a hybrid block–based coding scheme.

Linear Complexity of Several New Classes Sequences Based on Euler Quotient Modulo pmqn With Different Periods

Journal of Mathematics, Volume 2026, Issue 1, 2026.
Pseudorandom sequences with large linear complexity are widely employed in practical secure communication systems, such as stream ciphers, spread‐spectrum communications, and wireless networks. They play a critical role in enhancing resistance against linear cryptanalysis.
