Related-Key Differential Attacks on COSB-128
COSB-128 (Moldovyan et al., 2002) is a block cipher with 128-bit and 256-bit secret keys, which use key and data-dependent operational substitutions in fast controllable permutation blocks (CPB) concept.

FPGA Realization of a Novel Hyperchaos Augmented Image Encryption Algorithm
With the rapid growth of multimedia communication, protecting image data has become increasingly critical. This article proposes a novel 3‐stage hyperchaos‐based augmented image encryption technique (3SHAIET) that utilizes a three‐stage process with chaotic systems of increasing dimensionality (e.g., six‐dimensional [6D], 8D, and 9D) to enhance ...

Recent proposals by Mahmood et al., Braeken et al., and Chaudhry et al. aimed at establishing secure communication in AMI, asserting their methods fulfil the requisite security criteria. This paper, however, reveals that each of these proposals exhibits security vulnerabilities and lacks sufficient features for deployment.

Probability distributions of correlation and differentials in block ciphers
We study the probability distributions of difference propagation probabilities and input-output correlations for functions and block ciphers of given dimensions, for several of them for the first time.

Generating Graphs Packed with Paths Estimation of Linear Approximations and Differentials
When designing a new symmetric-key primitive, the designer must show resistance to known attacks. Perhaps most prominent amongst these are linear and differential cryptanalysis. However, it is notoriously difficult to accurately demonstrate e.g.

This paper proposes a secure electrocardiogram (ECG)‐processing framework that digitises ECG waveforms from clinical paper or image‐based records and encrypts them using a dual chaotic cryptographic scheme. The method supports both extracted and native digital signals, ensuring strong security and interoperability for Internet of Medical Things ...

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

New Experimental Results in Differential — Linear Cryptanalysis of Reduced Variants of DES [PDF]
At the beginning of the paper we give an overview of the linear and differential cryptanalysis of block ciphers. We describe two extensions of linear cryptanalysis (analysis with multiple expressions [7] and differentiallinear cryptanalysis [10] which form the basis of the conducted experiments.

This paper introduces a hybrid image encryption method that combines DNA coding, elliptic curve cryptography and chaotic systems to securely protect specific regions of interest identified by you only look once, version 2. The approach achieves high security through near‐ideal entropy and resilience against attacks, making it particularly suitable for ...
