【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、伪随机性等特点,在发送端,将图像信息首先经过常规加密技术DES加密,然后再经过混沌序列进行二次加密。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DES与混沌序列的级联加密,发挥它们各自的优点,使图像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。更多还原

【Abstract】 In this paper,a scheme of image secure communication is presented.The image is encrypted by DES algo-rithm combined with chaotic sequences at the transmitter.Accordingly,the received signal is decrypted.Taking advantages of DES algorithm and chaotic sequences,the communication system is securer than that using any encryption technique lonely.The computer simulation results show that our proposed image secure communication scheme is effective.更多还原
