Research on high-intensity commercial cryptographic security management methods for terminal intelligence in power distribution area

Abstract： The security services of the intelligent fusion terminal in the low-voltage distribution area are concentrated in the security chip, including the storage and use of keys, the identity authentication with the cloud side, and the encryption and decryption of data. Aiming at the problems of high hardware cost and complex key management in the centralized forwarding scheme of intelligent converged terminal security services, a method of data interrupt caching and service queuing distribution is proposed through the structured design of protocol and state machine polling, which realizes the fusion of multiple security services on one security module. The fusion scheme makes full use of the idle time slice of the security module. The key management of different services is unified, and the feasibility and reliability of this method is verified by functional and stress tests. It achieves the purpose of cost reduction and efficiency increase, and proves that the security service integration of intelligent fusion terminal in distribution station area is technically feasible, economically sparing and necessary in service.
