In this paper, a novel image block encryption algorithm based on three-dimensional Chen chaotic dynamical system is proposed. The algorithm works on 32-bit image blocks with a 192-bit secret key. The main idea is that the key is employed to drive the Chen's system to generate a chaotic sequence that is inputted to a specially designed function G, in which we use new 8 times 8 S-boxes generated by...
Recently, the chaos based cryptographic algorithms have suggested some meaningful techniques to develop efficient image encryption schemes. In this paper, we propose a new digital image encryption scheme based on the piecewise linear chaotic map (PWLCM) in order to meet the requirements of the secure encryption. The proposed scheme is described in detail, along with the security analyses including...
