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 ...

A McEliece cryptosystem using permutation codes
Journal of Mathematical CryptologyThis paper is an attempt to build a new public-key cryptosystem, similar to the McEliece cryptosystem, using permutation error-correcting codes. We study a public-key cryptosystem built using two permutation error-correcting codes.

An Efficient and Practical Public Key Cryptosystem with CCA-Security on Standard Model
Tsinghua Science and Technology, 2014 Chosen Ciphertext Attack (CCA) security on the standard model is widely accepted as the standard security notion for the public key cryptosystem. The existing CCA-secure public key cryptosystems on the standard model are expensive in terms of efficiency ...

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.

On McEliece-Type Cryptosystems Using Self-Dual Codes With Large Minimum Weight
IEEE Access, 2023 One of the Round 3 Finalists in the NIST post-quantum cryptography call is the Classic McEliece cryptosystem. Although it is one of the most secure cryptosystems, the large size of its public key remains a practical limitation. In this work, we propose a

Resisting Quantum Key Distribution Attacks Using Quantum Machine Learning
IET Quantum Communication, Volume 7, Issue 1, January/December 2026.Quantum key distribution (QKD) promises secure communication but remains vulnerable to advanced quantum attacks. We propose a hybrid quantum long short‐term memory (QLSTM) model that combines quantum‐enhanced learning with classical deep learning to detect attacks such as photon‐number splitting, Trojan‐Horse and detector blinding.

Cryptanalysis of McEliece’s Public-Key Cryptosystem [PDF]
, 2007 An approach is proposed for the cryptanalysis of the well-known version of McEliece's public-key cryptosystem that is based on a new iterative optimization algorithm for decoding an arbitrary linear code. The algorithm provides guaranteed correction of all error patterns with Hamming weight less than d/2, where d is the minimum distance of the code ...
