Relay protection fixed value online distribution management system and its security protection
In order to realize the online distribution of relay protection value and meet the security requirements such as confidentiality, integrity, authenticity and non-repudiation in the process of online distribution of fixed value, this paper analyzes the demand for the online distribution management system of relay protection. This paper design fixed value online flow module, device parameter upload module, system authentication and access control module, SSL/TLS protocol communication module. Based on two-factor authentication, task-based access control strategy and SSL/TLS protocol, data encryption/decryption scheme and protection scheme of system security based on secure channel are designed. Using C# language, SQL database and OpenSSL development tools, the relay protection online distribution management system with functions of fixed value single entry, fixed value single check, fixed value single approval and equipment parameter uploading has been developed. The practical application results show that the system can reliably realize the online circulation of relay protection fixed value and meet the security requirement of online distribution of fixed value.
