Executive Summary

Recently, there has been an increased focus and a sense of urgency in developing standards for Power Grid systems centered on the need for interoperability. Given the threat against these systems an important goal is the development of effective cyber security standards. However, past experience shows that security protocols are prone to design errors. Focusing on authentication protocols, this paper discusses key design principles and engineering practices that the authors believe can help ensure the correctness and effectiveness of standards for authentication in Power Grid protocols; e.g., DNP3.
