Image encryption using the new two-dimensional Beta chaotic map

To further improve the security of the image encryption methods based on chaotic maps, we created a new two-dimensional chaotic map called two Dimensional Beta Chaotic Map(2D-BCM) driven from the one-dimensional Beta chaotic map(1D-BCM). This paper describes a new image encryption approach based on 2D-BCM. The new 2D-BCM is used to produce chaotic sequences. These sequences were used to create the encryption key. The proposed algorithm is composed of three main steps: Permutation, diffusion, and substitution. For the proposed scheme, the generally used metrics of security, and sensitivity to initial conditions are effectively determined with the help of a selection of standard simulation results. In comparison to prior schemes, the obtained results of various types of security analysis show that the newly created 2D-BCM has high sensitivity and security.
