Enhancing Medical Image Security Leveraging Quantum Key Distribution

IET Quantum Communication, Volume 7, Issue 1, January/December 2026.
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.

A Secure Color Image Encryption Method Using Genetic Algorithm–Based Pixel Permutation and Multimap Chaotic Diffusion

Applied Computational Intelligence and Soft Computing, Volume 2026, Issue 1, 2026.
Images transmitted across open networks, such as the Internet, are inherently vulnerable to eavesdropping, unauthorized access, and data tampering. Sensitive image categories, including medical, military, biometric, and legal images, often require a higher level of protection than public protocols provide. Moreover, the large size, high redundancy, and

Safe and Quickest Medical Image Encryption Using Logistic Map Derived S‐Boxes and Galois Field

Computational and Mathematical Methods, Volume 2026, Issue 1, 2026.
The pseudorandomness, simplicity of use, and extreme sensitivity to even the slightest change in the initial value and handling parameters make chaotic maps attractive. The use of medical imaging to diagnose illnesses has grown in significance. These photographs need strong security measures because they are exchanged over public networks.
