摘要
常用的PC级加密算法运算量过大,不适合在嵌入式设备上运行。为了使嵌入式设备的数据存储及传输能够安全地进行,利用混沌信号对数据进行加密以提高嵌入式设备数据的安全性。在ARM2440+Linux平台上实现了混沌信号生成功能并利用混沌信号对数字图像进行加密的实验,最终生成加密后的一份密文信息。
The ordinary encryption algorithm based on the computer is not suitable for the embedded devices due to considerable computation. But in order to protect the data in embedded system when saving or transmitting, encrypt the data with chaotic characteristic as well as porting it in the embedded devices improves the security of data transmission. Do some experiment which include chaotic signals and encrypt the data with chaotic signals in the ARM2440 ＋ Linux platform, at last create an encrypt file.
