An Information Security Control Method of Smart Substation

摘要

The three layer equipment of IEC61850-compliant Smart Substation connecting directly to the Ethernet for the benefit of information transmission and sharing. However, it also brings certain information security risks. This paper proposes evolution ring based message security control scheme, which uses the high-speed hardware encryption core to ensure the security of GOOSE, SV and MMS messages. The result of time consuming analysis indicates that the proposed scheme can not only guarantee the security of messages, but also meet the message real-time transmission requirements of Smart Substation.
