A New Image Encryption Algorithm Based on CML and DNA Sequence
Xingyuan Wang, Yutao Hou, Shibing Wang, Rui Si Li · IEEE Access · 2018
In this paper, a new image encryption scheme based on CML and DNA sequences is proposed. First, a kind of DNA encoding rule is selected to encode the original image to a DNA matrix. Then, we perform a cyclic shift on the even rows and columns of the DNA matrix and then perform further index scrambling operations on the odd rows in the scrambled DNA matrix. Using the DNA sequence generated by the CML system and designed DNA calculation rules, the scrambled DNA matrix is further diffused. Finally, decode the diffused DNA matrix and get the final encrypted image. Simulation experiments and security analysis show that the scheme achieves the satisfactory effect and has the capacity to resist all kinds of classical attack methods.
