Image Cipher Using a New Interactive Two-Dimensional Chaotic Map

In this paper, a new two-dimensional (2D) Tent cascade-Logistic map (2D-TCLM) is introduced. Analysis results demonstrate that it has complex chaotic behaviors. Using 2D-TCLM, a new image encryption algorithm is also proposed. Simulation results and security analysis show that it can encrypt different kinds of digital images into unrecognized random-like images with a high security level.
