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

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.
