Through the use of smart devices, the systems in the power grid get interconnected between each other and remote networks. Especially the remote access to the critical smart grid environment involves new challenges in the area of security. To ensure the transmitted data and the access to the system is secured, cryptographic mechanisms have to be implemented. One critical part in this task is the management of cryptographic keys. This paper explains and defines a set of basic requirements for cryptographic key management in the smart grid. These requirements are derived from challenges present in common corporate environments. Then, basic approaches in the field of key management are stated and evaluated for the applicability in the power system. Different protocols for the implementation of key management strategies are shown and an assessment regarding their suitability for the defined requirements is conducted.
