| Abstract | The power grid is becoming increasingly interconnected, as information from grid operations must be accessible to an array of engineers, grid regulators, and market operators. However, there remain challenges ensuring the appropriate integrity and authenticity of the grid information. While traditional cryptographic protocols, like public key infrastructure, provide security for in-transit communication, they come with key exchanges and cost to get public key certificates from a centralized authority. To address these challenges, this paper demonstrates how a hash calendar-based blockchain can be used to provide improved security for communication with the use of distributed ledgers. It demonstrates the security requirements and threats to this communication, and then provides a theoretic definition of the process. Furthermore, it introduces a use-case of the proposed process within the WSU Smart City Testbed DMS where the historian data is hashed and signed using hash calendars. © 2019 IEEE. |
