The increasingly prominent network security issues are challenging rigorously the security protection of HVDC control and protection systems.This paper proposes an endogenous security design method for HVDC control and protec-tion systems based on the architecture of HVDC control and protection systems.According to the framework of the trus-ted active defense system,a trusted security management center is established,and the trusted nodes are designed for the operator layer,control protection layer and field layer.The proposed system can help improve the overall protection level of HVDC.
