Parallel Bit-Level Image Encryption Using a Two-Dimensional Sine-Coupled Map and Josephus Scrambling

This paper presents a parallel bit-level image-encryption scheme based on a two-dimensional sine-coupled chaotic map, a plaintext-dependent SHA-256 key-derivation step, Josephus-based bit scrambling, and feedback diffusion. The image is divided into high- and low-order bit groups, which are scrambled using chaotic sequ...

An Optimized Cascaded Cryptosystem Using AES-256 and SPECK-128

Experimental results demonstrate that the AES-256 + SPECK-128 framework achieves near-ideal information entropy, drastically reduces adjacent pixel correlation from  to, and satisfies theoretical differential attack resistance baselines, confirming the system's suitability for real-time, low-latency secure image transm...
