Design and Implementation of Security Protection for Service Call in New Generation Dispatching Technology Support System

To meet the needs of future power system development and safe, stable, and high-quality operation, it is proposed to build a new generation of dispatching technology support system. The new generation dispatching technology support system fully inherits the achievements of the smart grid dispatch control system, inherits the boundary security protection strategy of the original smart grid dispatch control system, and provides comprehensive security protection for all internal links of the system. This paper introduces the use of secure communication bus, security reinforcement based on authentication and encryption technology, and the use of signature verification, encryption and decryption, Anti-replay and other secure communication technologies for communication transmission between applications.
