Abstract
The methods of conventional encryption cannot be applicable to images for the resistance to statistic attack, differential attack and grey code attack. In this paper, the confusion is improved in terms of chaotic permutation with ergodic matrix, and the diffusion is implemented through a new chaotic dynamic system incorporated with a S-box algebraic operation and a ’XOR plus mod’ operation, which greatly enhances the practical security of the system with a little computational expense, and a key scheme is also proposed. Experimental and theoretical results also show that our scheme is efficient and very secure.
