Research and Application of SM9 in the Ubiquitous Electric IoT

With the continuous advancement of the reform of the power system, relying on new technologies such as big data, cloud computing, artificial intelligence, the IoT, and blockchain, the construction of the ubiquitous electric IoT has promoted data fusion in all aspects of the system and broke the isolation of data island. However, due to the large scale of system access, the complexity of business operations, and the increasing number of system vulnerabilities and vulnerabilities, it is difficult for traditional network security technologies to ensure system security. The certificateless security mechanism based on domestic passwords can effectively solve the security problems brought by massive terminal access and ensure the stable operation of the power system. In order to meet the security requirements of energy Internet information interaction, this article proposes the SM9 cloud service constructed by converged cloud technology for large-scale terminal interconnection scenarios, and integrates the challenge handshake authentication protocol (CHAP) to prevent Identity authentication affected by replay attacks, improving the security management and control capabilities of terminal access, and comprehensively supporting the construction of world-class energy Internet companies with excellent competitiveness.
