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.

Some properties of impossible differential and zero correlation linear cryptanalysis on TEA family‐type ciphers

open access: yesSecurity and Communication Networks, 2016
AbstractIn lightweight cryptographic primitives, round functions with simple operations XOR, modular addition, and shift (or rotation) are widely used nowadays. Among these ciphers, TEA and XTEA are two famous lightweight block ciphers. At AFRICACRYPT 2012, Jiazhe Chen, Meiqin Wang, and Bart Preneel proposed a method to establish impossible ...
