Abstract:

 Currently, protocol IEC61850 is widely used in smart substations. The feature of openness stay hidden defects in the information security. This paper transformed
the field in the application layer protocol which based on IEC61850 mapping to MMS, GOOSE, SV and designed an encryption and authentication mechanism using the Public Key
Infrastructure (PKI) theory in the application layer protocol transmission. This method ensures the confidentiality, integrity, non-repudiation of protocol IEC61850 in
transmission. The experiment proved the feasibility and effectiveness using message after transformation.

Key words: IEC61850, PKI, information security in smart substation, encryption technique in application layer protocol
