چکیده
A novel chaotic, permutation-substitution architecture based, grayscale images’ encryption algorithm is introduced in this paper. To reduce the redundancies of Fridrich’s structure based image encryption scheme, a novel inter-intra bit-level permutation based confusion strategy is appealed. The confusion stage is developed with the aid of KenKen puzzles. Theoretical analysis and simulation results show that the proposed method has many of the desired properties of a secure cipher.
