%X In order to improve the attack-resistance's ability and security of encryption,this paper discussed the method for image encryption,and presented an improved method.By combining Clifford hyper chaotic system and Logistic chaotic system,got a better Cli-Log chaotic system,and it could be used for disturbing pixels' location.Then inserted parameters into Chua chaotic system via Runge-Kutta method,got chaotic sequences,and used the sequences to do XOR operation with image pixels.Finally realized encryption.Thi...
