| Summary: | Aiming at the terminal access and terminal communication security problems under Power IoT, a full lifecycle security management scheme for terminal keys under Power IoT is proposed in this paper. Firstly, the two-stage key distribution architecture based on the state secret algorithm is adopted in the scheme to achieve secure access authentication of power terminals at different stages. Secondly, the group key management model based on logical key hierarchy is adopted in the scheme to achieve lightweight encryption of unicast and broadcast data to secure the communication of power terminals. In addition, different storage and access management strategies are adopted in the scheme to shorten the access time of terminal keys by implementing hybrid storage and management of terminal keys according to key usage. The performance analysis shows that compared to the traditional access authentication and key management scheme based on logical key hierarchy, the scheme of this paper optimizes the terminal computation, reduces the computational overhead and simplifies the key update process. Compared to conventional terminal key storage and management methods, the scheme of this paper improves key access performance without changing the existing hardware platform. |
