摘　　要：数字化仪控系统中,远程接收数据和远程操控的应用场合越来越广泛。在信息安全的大时代背景下,特别是一些特殊应用场合,通信数据加密成为首要需求。DES、AES等加密算法在软件层通信比较广泛,此处介绍的应用是硬件和软件通信,双方协商先互通密钥再互通数据,并动态修改密钥的方法来加密数据。In the digital instrument control system,the application of remote receiving data and remote control is more and more popular.In the background of information security,especially in some special applications,communication data encryption becomes the primary requirement.DES,AES encryption algorithms is more extensive in the software communication system,but the application described here is between a hardware and a software communication system.The hardware and the software must exchange the key first and then exchange data which is encrypted.Dynamically modifying the key is also a method to encrypt the data.

关 键 词：加密 FPGA 动态密钥 通信数据
