Full title and description

IEC TS 62351-100-1:2018 — Power systems management and associated information exchange — Data and communications security — Part 100-1: Conformance test cases for IEC TS 62351-5 and IEC TS 60870-5-7. This technical specification defines conformance test cases intended to verify the correct integration of authentication mechanisms specified in IEC TS 62351-5 and IEC TS 60870-5-7 for protecting IEC 60870-5-101 and IEC 60870-5-104 based telecontrol communications.

Abstract

IEC TS 62351-100-1:2018 provides standardized conformance test cases and related procedures for data and communication security in telecontrol and substation automation systems. The document focuses on testing the implementation and integration of authentication mechanisms (as defined in IEC TS 62351-5 and IEC TS 60870-5-7) to reduce the risk of non-interoperability among devices and to provide repeatable, objective pass/fail criteria for security-related functions in IEC 60870-5-101/104 communications.

Scope

This technical specification specifies commonly available procedures, definitions and a set of conformance and interoperability test cases for validating the integration of authentication mechanisms specified in IEC TS 62351-5 and IEC TS 60870-5-7. The focus is on telecontrol equipment, substation automation systems (SAS), and SCADA front-end functions that use IEC 60870-5-101 and IEC 60870-5-104 protocols. Safety, EMC and other non-security requirements are out of scope and remain the responsibility of other standards.

Key topics and requirements

• Conformance test cases for authentication integration between IEC TS 62351-5 and IEC TS 60870-5-7 implementations.
• Structured test procedures with preconditions, test steps, expected results and pass/fail criteria.
• Test scenarios covering successful authentication, authentication failure modes, error handling and recovery.
• Interoperability-focused tests for IEC 60870-5-101 and IEC 60870-5-104 communication stacks using the specified authentication mechanisms.
• Guidance on test environment setup, test harness roles (test system and system under test), and required test artifacts/logging.
• Definitions and conventions to ensure repeatable, objective testing and minimise misinterpretation of test results.

Typical use and users

Used by product developers, test laboratories, system integrators and utilities to validate that telecontrol and substation automation devices correctly implement and integrate required authentication mechanisms. Test houses and certification bodies will use the specification to create conformance test suites; vendors will use it to verify device behavior before deployment; utilities and integrators will use test reports to assess interoperability risk.
