Abstract

IEC 62351-4 standard is published to address cybersecurity vulnerabilities of IEC 61850 Manufacturing Message Specification (MMS) messages. This standard includes a set of cipher suites that are recommended for securing MMS messages. However, these are only a set of recommendations. There is no work in the literature that implements them on an IEC 61850 MMS message and reports the performances. In order to fill this importance knowledge gap, this short communication reports results of implementing cipher suites recommended by IEC 62351-4 on IEC 61850 messages. In addition to implementation details, real message exchanges are demonstrated with lab experiments. Finally, changing certificate and message sizes are reported. The results show that cipher suite selection is critical as some suites have 29.67 % smaller certificate size than others. The novelty of this short communication is showing details of IEC 62351 application and relevant changes on message sizes and structures of IEC 61850 MMS messages. There is no similar work or publication showing such procedures and results.
