Enhancement of Secrecy of Block Ciphered Systems by Deliberate Noise

, 2012
This paper considers the problem of end-end security enhancement by resorting to deliberate noise injected in ciphertexts. The main goal is to generate a degraded wiretap channel in application layer over which Wyner-type secrecy encoding is invoked to ...

Hyperchaos‐Driven 3D RGB Image Scrambling and Encryption for Multi‐Image Security

IET Image Processing, Volume 20, Issue 1, January/December 2026.
The proposed encryption scheme scrambles N colour images by stacking them into a three‐dimensional red, green, blue image, generating a secure 256‐bit key using SHA‐256 and a user‐provided salt, and applying a five‐dimensional multi‐wing hyperchaotic system to produce random key streams.

Commutative Cryptanalysis Made Practical

IACR Transactions on Symmetric Cryptology, 2023
About 20 years ago, Wagner showed that most of the (then) known techniques used in the cryptanalysis of block ciphers were particular cases of what he called commutative diagram cryptanalysis.

A Novel Hybrid Image Encryption Scheme Using Henon Map for Secure Image Communication

IET Information Security, Volume 2026, Issue 1, 2026.
The combination of chaos theory and cryptographic methodologies constitutes a pivotal aspect of the information security. Owing to certain attributes of images, like their large data capacity and significant redundancy, image encryption needs specialized techniques instead of conventional text encryption.

Regular subgroups with large intersection

, 2018
In this paper we study the relationships between the elementary abelian regular subgroups and the Sylow $2$-subgroups of their normalisers in the symmetric group $\mathrm{Sym}(\mathbb{F}_2^n)$, in view of the interest that they have recently raised for ...

Enhancing E‐Commerce Security Based on Involution Function Using Twin Key AES Cipher

IET Information Security, Volume 2026, Issue 1, 2026.
In the realm of surging e‐commerce data and increasing digital transactions, ensuring end‐to‐end security is paramount to protect sensitive information and maintain user trust. The Advanced Encryption Standard (AES), a cornerstone of network security, relies on symmetric key encryption for secure communication.

MILP-Based Differential Cryptanalysis on Round-Reduced Midori64

IEEE Access, 2020
Mixed integer linear programming (MILP) model was presented by Sun et al. at Asiacrypt 2014 to search for differential characteristics of block ciphers. Based on this model, it is easy to assess block ciphers against differential attack.

Cryptanalysis of a one round chaos-based Substitution Permutation Network

, 2012
The interleaving of chaos and cryptography has been the aim of a large set of works since the beginning of the nineties. Many encryption proposals have been introduced to improve conventional cryptography. However, many proposals possess serious problems

Improvement of the Minimal‐Guess‐Basis MILP Model and Its Application to ESF

IET Information Security, Volume 2026, Issue 1, 2026.
The guess‐and‐determine technique find wide applications in the recovery of unknown variables within given system of relations. The fundamental concept behind this technique involves guessing certain unknown variables and deducing the remaining ones based on the relational system.
