摘　　要：针对机密信息的隐蔽安全传输问题,提出一种基于国密SM算法的应用层协议隐写系统。系统以国密SM算法为加密、认证基础,结合应用层协议隐写的特点,以框架式、插件化的设计思路,详细阐述系统的主要构成部分(发信端和收信端),构建系统总体架构,并进行系统测试。测试结果表明:该系统能够有效地对机密信息进行加密传输,实现了可扩展、多种协议并发的功能,具有一定的理论意义和实践价值。According to the confidential information secure transmission problem, put forward an application layer protocol steganography system based on cryptographic SM algorithm. This system based on the encryption and authentication of SM cryptographic algorithm, according to the characteristics of the application layer protocol steganography in frame type and plug-in design, elaborate the main part of system： the transmitting terminal and receiving terminal, build the system overall framework and carry on the system test. Experimental results show that this system can effectively to encrypted transmission of confidential information, realized the function of extensible and multiple protocols concurrentlv, which has a certain theoretical significance and nractical value.
