Aiming at the characters of the multimedia information such as images,a digital image encryption scheme based on chaotic map with variable intervals and standard map is proposed.Firstly,a real sequence is generated from the piecewise linear chaotic map with variable intervals and transformed into a pseudorandom binary sequence.Then,the pseudorandom sequence and the standard map are used for image encryption.Experimental tests with detailed theory analysis show,the high security and strongly against attack of the new scheme.
