چکیده مقاله:
Simple and effective chaotic system combined with a diffusion technique for grayscale image encryption is introduced in this paper. First, the RGB image converted to the grayscale image to encrypt it using a pixel mixing method and then, a ۳D logistic chaotic map used to form the cryptographickey sequences that performed on the ciphered image to obtain the initial encrypted image. Second, the new diffusion strategy performed on the initial ciphered image to improve the security of the image encryption. The simulation results show that the proposed method can improve the histogram uniformity of image encryption and it has superior confusion and diffusion properties compared to the other chaotic based algorithms, which stronglyresist statistical attacks.
