Abstract: 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.
