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.

Enhancing Medical Image Security Leveraging Quantum Key Distribution
This paper proposes QKD assisted quantum encryption for medical images. BB84 protocol is utilised to generate a secure shared key, which is further enhanced using Henon maps. The logistic map whose parameters are derived from the shared key is employed to generate the permutation sequence for pixel values.
