摘　　要：提出一种适合文本保密通信的混沌算法,在软件实现的同时也将该算法嵌入通信系统的信源和信宿,实现了算法的移植.发送端将明文通过算法加密后由天线发射,接收端收到密文后正确解密恢复明文.硬件平台由S3C4510B处理器、ST7920中文字型点阵LCD控制器、无线收发模块nRF2401A及PS/2键盘等共同搭建.该系统验证了混沌加密算法在信息安全领域的优势,同时具有一定的实用性,在工业、军事等领域具有开发价值.A chaotic encryption method suitable for the text is proposed and embedded in both the source and the receiver of the communication system. On the transmitter side, the message is encrypted and sent out, the receiver receives the cipher text and decrypts it. The system is composed of S3C4510, nRF2401, ST7920 LCD, PS/2 keyboard and so on. The result demonstrates that the proposed scheme is feasible, and worthy of development in both the industrial and military fields.
