Technical Field
[0001] This invention relates to the field of secure communication technology, and in particular to a secure communication method, system and storage medium for power control operations. Background Technology
[0002] The State Grid Data Communication Network is a comprehensive wide-area network transmission platform of the State Grid Corporation of China. It serves as the foundation for interconnecting various computer application systems within the State Grid system and is a crucial component of the power information infrastructure. Currently, the State Grid Data Network simultaneously carries real-time control and management information services. Although its network utilization is high, it still harbors numerous security vulnerabilities. While existing secure communication methods for power dispatching services can provide some security protection for the transmitted information on the State Grid Data Communication Network, the overall network security level is low, making it susceptible to the risk of power dispatching information leakage and resulting in low security for power dispatching communication.

[0006] Each transmission target is divided into several transmission sub-targets according to a preset separator, and the number of transmission sub-targets of each transmission target is marked as the transmission number.
[0007] The number of partitions is determined based on the initiation time, the number of transmissions, and the number of targets in the transmission target.
