Research And Implementation Of Distribution Network Security Interaction Gateway Based On SM2 Algorithm

With the gradual deepening of information technology in distribution network engineering,information security issues are gradually highlighted.At present,the one-way authentication technology based on SM2 algorithm is used in the data exchange between the distribution terminal and the distribution network,and most of the data exchange is carried out in plain text mode.Therefore,how to ensure the security of the terminal equipment and the distribution network data exchange has become an urgent problem to be solved in the process of distribution network construction.Realize the distribution network and distribution network security data exchange needs to solve two problems: one is the security of the distribution terminal itself;two is the data communication channel security.The security of the terminal itself ensures the security of the access source.The data communication channel security guarantees the security and integrity of the communication data.Based on the distribution business as the criterion,integration of cryptography algorithm technology,high concurrency communication architecture technology,PF_RING zero copy and high-speed data packet interception technology,designed a secure communication protocol,multi process communication architecture of asynchronous event triggered and complete PF_RING and Libnet technology based on data packet analysis and assembly model based on gateway system a fast high concurrent data packet analysis assembly,and separately from the distribution terminal,communication channel and its gateway etc.given the corresponding security reinforcement method,providing two-way authentication,data encryption,data communication,interaction and other protective measures for distribution network access equipment,ensure the safety of the power distribution network data exchange.The final performance test is carried out respectively on the gateway and distribution business data flow testing and distribution business concurrent testing,verify the rationality and reliability of the whole design of the system,and have achieved good effect in concurrency and load balancing.
