A color image encryption method based on improved 3D_Henon chaos mapping
Aiming at the problems of small chaotic space and weak chaotic ability of existing chaotic mapping models,a new three-dimensional chaotic mapping model is designed by coupling two-dimensional Henon chaotic mapping model and Sine chaotic mapping model.Aiming at the problem that the security of encryption system will be reduced if the key is reused,this paper designs a new key gen-eration method using Chebyshev mapping and plaintext image.Using the 3 D chaotic mapping and key generation method designed in this paper,a color image encryption method is proposed.The results show that the method can encrypt images safely and effectively and protect the security of image infor-mation.
