Abstract EN
A novel chaotic image encryption scheme based on the time-delay Lorenz system is presented in this paper with the description of Circulant matrix.
Making use of the chaotic sequence generated by the time-delay Lorenz system, the pixel permutation is carried out in diagonal and antidiagonal directions according to the first and second components.
Then, a pseudorandom chaotic sequence is generated again from time-delay Lorenz system using all components.
Modular operation is further employed for diffusion by blocks, in which the control parameter is generated depending on the plain-image.
Numerical experiments show that the proposed scheme possesses the properties of a large key space to resist brute-force attack, sensitive dependence on secret keys, uniform distribution of gray values in the cipher-image, and zero correlation between two adjacent cipher-image pixels.
Therefore, it can be adopted as an effective and fast image encryption algorithm.
