The express development of communication and technology has created new challenges to transfer data in a secured way. This paper presents a secure cryptosystem with three level security based on chaos for video encryption. The proposed method employs one round permutation and diffusion structure for encryption. The logistic and tent maps are combined (LTS) to generate the initial parameters for the proposed encryption system. The video frame is first selected based on Frame Selection (FS) is encrypted by applying permutation order (PO) and then diffusion is carried out on the permuted frame by diffusion frame (DF) generated. After encryption, the encrypted frame is placed in order, to create a video sequence for transmission. This method provides three- level security (FS, PO and DF) in extracting the encrypted information. Experimental outcomes and analyses confirm that the method is competent.
