基于国密算法的北斗短报文安全防护系统的研究与实现

针对目前国内北斗短报文通信在电力系统中越来越广泛的应用，加之电力系统安全防护要求的发布，本文以用电信息采集系统为例，分析北斗短报文通信应用现状及安全风险，结合电力系统安全防护要求，提出基于国密算法的北斗短报文通信的用采系统安全防护方案，实现北斗短报文用采系统业务数据的安全信息交换，包括双向身份认证、密钥协商和数据加密。最后，通过实验测试分析并证明其有效性。

Research and Implementation of Beidou Short Message Security #br# Protection System Based on National Secret Algorithm

In view of the increasing application of domestic Beidou short message communication in power system and the release of power system security protection requirements, this paper takes the electricity information collection system as an example to analyze the application status and security risks of Beidou short message communication. Combined with the power system security protection requirements, the security protection scheme of the mining system for the Beidou short message communication based on the national secret algorithm is proposed, and the security information exchange of the business data of the Beidou short message mining system is realized, including two-way identity authentication, key agreement and data encryption. Finally, the experimental test analyzes and proves its effectiveness.
