An Image Encryption Algorithm Based on Mixed Chaotic Dynamic Systems
Sun Bai · China Information Security · 2007
An image encryption algorithm based on mixed chaotic dynamic systems is proposed. With the map of the external keys,the initial conditions of the mixed chaotic dynamic systems are acquired. Subsequently the chaotic signals are generated,then the plain image is encrypted by masking the chaotic signals. The result of the simulation and analysis shows that the chaotic signals are greatly sensitive to the key. Moreover,a better security performance on the basis of statistical analysis is obtained.
