Design and Implementation of Data Transmission Security Channel Protocol for Intelligent Equipment in Modern Power Grid

摘要

With the increasing mutual interaction between smart grid and users, intelligent acquisition terminals and mobile operation terminals are widely used and accessed. The types of data transmitted in the network are more complex, and the requirements for information security protection are higher. Currently, the general security protocols for power systems do not meet the new requirements. This paper studies ISO/IEC 9798 series of standards, combines key agreement, entity authentication and hybrid algorithm technology, designs a secure channel protocol for high-security data transmission, and analyzes its complexity and time performance. Finally, it is completed based on security chip. Data transmission test shows that it has the characteristics of high security and flexible protocol, and can effectively meet the security and real-time requirements of data communication.
