IET Cyber-Physical Systems: Theory &Applications, Volume 11, Issue 1, January/December 2026.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.

Differential and Linear Cryptanalysis using Mixed-Integer Linear Programming
, 2011 Differential and linear cryptanalysis are two of the most powerful techniques to analyze symmetric-key primitives. For modern ciphers, resistance against these attacks is therefore a mandatory design criterion. In this paper, we propose a novel technique

Cryptanalysis of Stream Ciphers with Linear Masking [PDF]
, 2002 We describe a cryptanalytical technique for distinguishing some stream ciphers from a truly random process. Roughly, the ciphers to which this method applies consist of a "non-linear process" (say, akin to a round function in block ciphers), and a "linear process" such as an LFSR (or even fixed tables). The output of the cipher can be the linear sum of

Healthcare Technology Letters, Volume 13, Issue 1, January/December 2026.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
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.

An Efficient and Fast Image Encryption Scheme Based on a Novel One‐Dimensional Hybrid Chaotic System
IET Image Processing, Volume 20, Issue 1, January/December 2026.ABSTRACT Recently, images have been used widely in a variety of fields, including social media, the military and medicine. Sensitive images are often transmitted over insecure networks and chaotic maps offer effective cryptographic properties for securing these transmissions.
