Abstract:
An image encryption algorithm is put forward based on a method that the initial conditions and iteration time of a chaotic system are obtained from external keys,then image signals are encrypted using the subsequently produced chaotic signals.The simulated results show that the proposed algorithm is a good spatial design algorithm for chaotic keys,and possesses a large space of keys,fairly well encryption effect and excellent security to statistic analyses and different attacks.
Key words: external key, encryption, chaos, chaotic sequence
