Research on Secure Message Transmission of Smart Substation Based on GCM Algorithm

摘要

Based on IEC61850 standard smart substation system using ethernet architecture is required for higher information security. SMV, GOOSE, MMS are common messages used in smart substation , whether these messages can be transmitted secretly is critical to the security of the entire substation system. If each message uses an encryption algorithm, that is bound to increase the burden of equipment and affect its interoperability. For the security requirements, a common message authentication encryption algorithm based on GCM is proposed in this paper. By choosing different algorithm modes to achieve secure transmission of these messages, this algorithm can effectively improves the security of substation information and network performance.
