Image encryption algorithm based on 2D‐CLICM chaotic system

Image encryption algorithm based on a two-dimensional Chebyshev-Logistic-Infinite Collapse Map (2D-CLICM) is proposed. A new chaotic map designed, and numerical studies show that 2D-CLICM has larger region, better randomness more complex behavior. An image (CLICM-IE) developed the 2D-CLICM. The randomly generated key used to generate random sequences security greatly improved. To obtain lower computation time complexity, whole process performs row for each pixel. Arnold transformation preprocesses then of pixels accomplished by controlling confusion diffusion parts with sequence results CLICM-IE deeply unpredictable, resists variety attacks. These can provide good basis practical application chaos generation encryption.
