Experimental study of performance and vulnerabilities of IEC 61850 process bus communications on HSR networks

Modern power-network communications are based on the IEC 61850 series standards. In this paper we investigate the real-time performance, the vulnerabilities and the attack scenarios on the sensor level communication networks, more precisely on the Sampled Measured Value (SMV) protocol. There are two main contributions of our work. First, we evaluate statistically the measured real-time performance of the communication network. The second contribution is the description, implementation and experimental validation of the attacks on SMV protocol targeting electrical protection functions.
