| Abstract: | In this paper,an image encryption algorithm based on logisitic map is raised up and implemented.In order to improve the security of the algorithm,the image pixels is also further disrupted by cyclic shift,to generate the final encrypted image in this paper.Experiments show that the algorithm is easy to implement,fast calculate,having large key space,can resist ciphertext-only attack and so on. |
