IEC 61850 Communication Protocol Architecture is widely used in China's electricity system for communication between the substation automatic systems. Due to the lacking of corresponding security specification, the standards cannot guarantee the confidentiality, integrity as well as authentication in communication. This paper proposes a solution for this problem. The improved Handshake Protocol and Record Protocol are introduced between the application layer and the transport layer with less transmission of data and quick connect feature. Using this solution, the standards can meet both the electricity system for real-time and reliability requirements and the security requirements at the same time.
