Abstract

The invention discloses a power service secure transmission method and system based on edge calculation. The method comprises the steps: taking the easy eavesdropping during data unloading and the limited processing resources of a power service terminal as consideration factors, According to the processing capability of power terminal equipment, carrying out the edge calculation; the method comprises the following steps: respectively calculating energy consumption of power service for local calculation and secure unloading transmission energy consumption unloaded to a mobile edge calculation server, introducing a Lagrange function based on a physical layer protection technology of main channel capacity and eavesdropping channel capacity, establishing a transmitting power utility function for secure unloading, introducing a KKT condition equation, and establishing a secure unloading transmission power utility function for secure unloading; by calculating the optimal solution, the local optimal task allocation quantity of the power terminal equipment and the optimal transmitting power for safe unloading are obtained, the safe transmission of the power service is completed, the calculation and communication resources of the power terminal equipment are optimized, and the secrecy capacity and the safety of the system are improved.

Description

technical field [0001] The present invention relates to the technical field of electric power wireless communication, in particular to a method and system for secure transmission of electric power services based on edge computing. Background technique [0002] With the development of wireless network technology, the demand for power services and network upgrades further drive the development of edge computing. Due to insufficient cloud computing capabilities, it cannot meet the explosive growth of massive data demand, and the sharp increase in transmission load leads to longer delays, which cannot meet Real-time requirements, due to the limited computing power and battery power of power terminal equipment, and as the complexity of access equipment increases, the resources of power terminal equipment are limited, and the data security and user privacy of power terminal equipment are also threatened. The problem of low data security when the device offloads tasks to the edge c...
