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

open access: yesComputational 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.
