Modeling and Analysis of a Cyber-Attack in an IEC 61850 Scenario using Colored Petri Nets

Abstract

Some performance parameters of the IEC 61850 standard related to the electrical measurements in electrical power systems are defined, and these parameters are really important and critical in the automation of these systems. Related to network security analysis, a tool used is the Colored Petri Net (CPN) because it models both concurrent and asynchronous processes and is useful for analyzing data modifications in timed systems. Thus, based on this context and knowing that time is really critical in the transmission of messages in the context of the IEC 61850 standard, a cybernetic attack is modeled using CPNs to modify the data related to electrical measurements, which is really critical for the functioning of the system. The results corresponded to the modeled cybernetic attack, showing the effectiveness of the proposed modeling method.
