摘　　要：在雷达数据采集系统,特种行业的安防、监控系统等DSP平台下,通过使用加密手段来保证其数据传输的私密性具有重要意义。介绍了密码体制的基本概念及分类,对从属于对称密码体制的典型对称密码算法原理进行了分析,给出了DES、3DES和AES等3种对称密码算法在TMS320C6713下的性能测试方法以及测试结果,得出了AES算法最适于在DSP环境下对视频数据进行加密的结论。Under the DSP platform such as radar data acquisition system,the security of construction industry,the monitoring system,ensure the security of data transmission through the use of encryption method has important significance. This paper firstly introduces the concept and the classification code system. After analyzd the principle of the symmetric encryption algorithm. Finally,introduced the performance test methods and test results of DES,3DES and AES under the TMS320C6713,and has the conclusion that the AES algorithm is the most suitable for the video data encryption under the DSP.
