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.

Cryptanalysis of NBC-128

Dianzi Jishu Yingyong, 2021
NBC is a family of block ciphers using Generalized Feistel structure, designed by Xu Hong et al. There are three block and key sizes,i.e.,128/128, 128/256 and 256/256. A 16-bit Sbox is involved in the cipher as the non-linear component.
