摘要： 提出了一种新型的图像保密通信技术。利用混沌序列对初值敏感性﹑伪随机性的特点,在发送端,将图像信息用混沌序列加密,再通过常规加密技术DES进行二次加密。接收端对收到的信号进行相应的图像解密,恢复出原始图像。这样,可实现对图像的混沌序列与DES的级联加密,发挥它们各自的优点,使保密通信的安全性得到提高。计算机仿真结果表明该方案的有效性。

Abstract: A scheme of image secure communication is presented.The image is encrypted by chaotic sequence combined with DES algorithm at the transmitter.Accordingly,the received signal is decrypted.Taking advantages of chaotic sequence and DES algorithm,the communication system is securer than that using any encryption technique lonely.The computer simulation results show that the proposed image secure communication scheme is effective.
