Journal of Informatics and Web EngineeringChaos-based cryptography has yet to achieve practical, real-world applications despite extensive research. A major challenge is the difficulty in analysing the security of these cryptosystems, which often appear ad hoc in design.

Flaws in Differential Cryptanalysis of Skipjack [PDF]
, 2002 This paper is motivated by some results presented by Knudsen, Robshaw and Wagner at Crypto'99, that described many attacks of reduced versions of Skipjack, some of them being erroneous. Differential cryptanalysis is based on distinguishers, any attack should prove that the events that triggers the analysis has not the same probability for the cipher ...

Safe and Quickest Medical Image Encryption Using Logistic Map Derived S‐Boxes and Galois Field
Computational and Mathematical Methods, Volume 2026, Issue 1, 2026.The pseudorandomness, simplicity of use, and extreme sensitivity to even the slightest change in the initial value and handling parameters make chaotic maps attractive. The use of medical imaging to diagnose illnesses has grown in significance. These photographs need strong security measures because they are exchanged over public networks.

Truncated differential cryptanalysis of PRINCE
Security and Communication Networks, 2015 AbstractPRINCE is a lightweight block cipher whose block size and key size are 64‐bit and 128‐bit, respectively. The core component of PRINCE is PRINCE which is wrapped by the initial and final key whitening. PRINCEcore adopts a 12‐round SPN structure.

Differential Cryptanalysis for Multivariate Schemes [PDF]
, 2005 In this paper we propose a novel cryptanalytic method against multivariate schemes, which adapts differential cryptanalysis to this setting. In multivariate quadratic systems, the differential of the public key is a linear map and has invariants such as the dimension of the kernel.

A Generalization of Gaussian Balancing and Gaussian Balancing‐Lucas Numbers With Applications
International Journal of Mathematics and Mathematical Sciences, Volume 2026, Issue 1, 2026.In this paper, we study a generalization of Gaussian balancing and Gaussian Lucas‐balancing numbers, we find their generating functions, Binet formulas, related matrix representation, and many other properties. Also, we provide some applications in cryptography.

Differential-Linear Cryptanalysis of Serpent [PDF]
, 2003 Serpent is a 128-bit SP-Network block cipher consisting of 32 rounds with variable key length (up to 256 bits long). It was selected as one of the 5 AES finalists. The best known attack so far is a linear attack on an 11-round reduced variant.

Security analysis of an encryption scheme based on nonpositional polynomial notations
Open Engineering, 2016 The aim of the research was to conduct a cryptographic analysis of an encryption scheme developed on the basis of nonpositional polynomial notations to estimate the algorithm strength. Nonpositional polynomial notations (NPNs) are residue number systems (
