In view of the above problems, this scheme studies and proposes a lightweight access authentication management method for complex power end-side devices. Firstly, on the basis of analyzing the specific performance of power end-side devices, the authentication requirements of devices are analyzed, including identity authentication and authority control requirements, as well as batch authentication requirements in the face of group tuning and group control scenarios. Then, a lightweight access authentication management method for power end-side devices is proposed, which realizes the initial key distribution of devices based on lightweight cryptographic resource pool, and a lightweight access authentication management method based on dynamic group is designed to realize batch authentication of end-side devices and data upload, and group device authentication. Finally, the performance analysis and security analysis show that compared with the existing typical group authentication schemes, the proposed scheme can ensure the security and reduce the calculation cost. |
