Analysis of Design Constraints and System Impact of DER Cryptographic Module
- Sandia National Laboratories (SNL-NM), Albuquerque, NM (United States)
In designing a security module for inverter communications in a DER environment, it is critical to consider the impact of the additional security on the environment as well as what types of security is required for the various messages that must pass from the inverter to and from a utility. Also, since cyber security is more than just preventing an unauthorized user from viewing data, mechanisms for proving identity and ensuring that data cannot be altered without such a modification being discovered are needed. This is where the security principles of confidentiality, integrity, and availability come into play. For different types of communications, these different security principles may be important or not needed at all. Furthermore, the cost and constraints for applying cryptography for securing DER communications must be considered to help determine what is feasible within this environment and what will be the impact and cost of applying common cryptographic protections to inverter communications.
