Security Analysis of SKINNY under Related-Tweakey Settings

IACR Transactions on Symmetric Cryptology, 2017
In CRYPTO’16, a new family of tweakable lightweight block ciphers - SKINNY was introduced. Denoting the variants of SKINNY as SKINNY-n-t, where n represents the block size and t represents the tweakey length, the design specifies t ∈ {n, 2n, 3n}. In this

A Secure Color Image Encryption Method Using Genetic Algorithm–Based Pixel Permutation and Multimap Chaotic Diffusion

Applied Computational Intelligence and Soft Computing, Volume 2026, Issue 1, 2026.
Images transmitted across open networks, such as the Internet, are inherently vulnerable to eavesdropping, unauthorized access, and data tampering. Sensitive image categories, including medical, military, biometric, and legal images, often require a higher level of protection than public protocols provide. Moreover, the large size, high redundancy, and

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‐

Impossible differential cryptanalysis of MARS‐like structures

IET Information Security, 2015
The MARS‐like structure is a generalised Feistel structure. Unified impossible differential (UID) method is an effective method to discover impossible differential characteristics for block cipher structures. In this study, for a specific kind of MARS‐like structure, the authors use UID to show that when n
