Particular Issues of Implementation of Embedded Cryptographic Instruments of Information Protection Digital Substation Devices Exchanging Messages IEC 61850-8-1 Protocol (MMS)

The design and construction of highly automated substations (HAAS) involves the implementation of digital information exchange according to the requirements of the IEC 61850 standard. In accordance with STO PJSC FGC UES “Digital substation. Methodological guidelines for the design of DSS” [1] , in each of the possible substation construction architectures, the IEC 61850-8-1 (MMS) data transmission protocol is used, which is based on the TCP/IP protocol set, possessing several known vulnerabilities, both at the level of implementation and fundamentally susceptible to computer attacks.
