Abstract
A new chaotic, permutation-substitution architecture based, image encryption algorithm has been introduced with a novel inter-intra bit-level permutation based confusion strategy. The proposed image cryptosystem uses Sudoku grids to ensure a high performance diffusion process and key space. This paper presents a fully comprehensive set of security analyses on the newly proposed image cryptosystem, including statistical and differential analysis, local and global information entropy calculation and robustness profile to different types of attacks. Based on the good statistical results, rounded by the theoretical arguments, the conducted study demonstrates that the proposed images’ encryption algorithm has a desirable level of security.
