3 Introduction to the ANSI C12 Suite of AMI Communications (and Operations) Protocols for Gas, Water & Electricity The publication of four North-American standards ANSI C (MC /IEEE ) : point-to-point access ANSI C (MC /IEEE P ) : gas/water/electricity ANSI C (MC /IEEE ) : telephone access ANSI (MC /IEEE P : network access And the release of Measurement Canada publication MC IS-E-01, Event loggers (and audit requirements) for metering devices and systems Resulted in Infusion of new C12.19-based metering products into the marketplace by virtually all of the major electricity meter manufacturers Being identified in the NIST report as key standards that need to be considered to achieve Utility Enterprise interoperability Forming the basis of the SmartGrid/AEIC AMI Interoperability Standard Guidelines for ANSI C12.19 End Device Communications and Supporting Enterprise Devices, Networks and Related Accessories Formation of the semantic models, network nodes and security registry

4 NIST Framework and Roadmap for Smart Grid Interoperability Standards Describes a high-level conceptual reference model for the Smart Grid Identifies ~75 existing standards that are applicable (or likely to be applicable) to the ongoing development of the Smart Grid Specifies 15 high-priority gaps and harmonization issues for which new or revised standards and requirements are needed Documents action plans with aggressive timelines to bridge gaps

13 ANSI C ANSI General Features Provide industry-wide, nation-wide and world-wide bidirectional network Application Interoperability Provide network independent end-to-end security Enable exchange of meaningful and actionable information Provide a common understanding of the meaning of information Support auditing and event logging per MC Requirements Enable external calculations that can be secured, validated and traceable to the calibrated source Supported by a managed object model (through registry of End Device Classes) Provide XML-based Exchange Data Language (schema)

Message acceptance windows and playback rejection mechanisms 5. Message authentication and encryption mechanisms 6. Message filtering mechanisms 7. Session-based and session-less invocation-id exchange 8. Network and path independent message integrity and assembly 9. PLUS additional security mechanisms that can be provided transparently by network integrators. However, they should act only to enhance while preserving the ANSI and ANSI C12.19 security provisions
