IEC 62351 – Security for IEC 61850
IEC 62351 is a standard developed to provide additional security of a series of protocols including the IEC 60870-5 series, IEC 60870-6 series, IEC 61850 series, IEC 61970 series & IEC 61968 series.
The various security objectives include authentication of data transfer through digital signatures, ensuring only authenticated access, prevention of eavesdropping, prevention of playback and spoofing, and intrusion detection.
Xelas Energy has implemented 62351-4 for MMS security, and 62351-6 for GOOSE/SV security.
IEC 62351-4: Security for any profiles including MMS ( ICCP-based IEC 60870-6, IEC 61850) contains the following sections:
- Authentication for MMS.
- TLS (RFC 2246) is inserted between RFC 1006 & RFC 793 to provide transport layer security.
- TLS stands for Transport Layer Security and defines encryption algorithms.
- RFC1006 is the standard which defines OSI on top of TCP/IP. The RFC1006 stack is completely developed and maintained by Xelas Energy Software.
- RFC 793 is the standard which defines TCP/IP.
IEC 62351-6: GOOSE / SV Security
This security module is available for both the regular GOOSE/SV protocols as well as the R-GOOSE/R-SV protocols.
Integration with Xelas Energy Management Products
IEC-62351-4 and IEC-62351-6 security is integrated with the IEC 61850 client development and embedded server/client development products as an optional plugin.
