摘要
由于嵌入式设备的数据安全越来越受人们的重视,但目前市面上关于嵌入式设备的数据加密算法还不够成熟。为了使嵌入式设备的数据存储及传输能够安全地进行,加密算法是采用八维混沌猫映射,这样能够提高嵌入式设备图像数据的安全性,并且在ARM2440平台上实现了混沌数字图像的加密与解密。嵌入式系统的图形界面是采用Qt界面,这样省去了繁杂的指令输入,简化了嵌入式设备人机交互的操作。
As a result of the embedded devices data security is more and more attention by people,but currently data encryption algorithm on embedded devices is not mature enough.In order to make the data storage and transmission safely of embedded devices,this paper use an eight dimensional chaotic cat map as encryption algorithm.It can enhance the security of embedded devices image data,and on the ARM2440 platform to realize the chaotic digital image encryption and decryption.
