Information security has gained tremendous importance for energy distribution and energy automation systems over the last years. Security for the smart grid is crucial to ensure reliability and continuous operation of the smart grid. However, the smart grid comes along with new use cases that impose new challenges on existing standards like IEC61850. IEC61850 offers standardized communication services and standardized data models for communication in energy automation, hence it is beneficial for the realization of the smart grid. IEC 61850 is flanked by the standard IEC 62351 that addresses security and specifies technical requirements, which have to be met by vendors.
