scope:

This technical specification which is part of the IEC 62351 describes test cases of data and communication security for telecontrol equipment, Substation Automation Systems [SAS] and telecontrol systems, including front-end functions of SCADA. The goal of this part of IEC 62351 is to enable interoperability by providing a standard method of testing protocol implementations to verify that a device fulfils the requirement of the standard. Note that conformity to the standard does not guarantee interoperability between devices using different implementations. It is expected that using this specification during testing will minimize the risk of non-interoperability. A basic condition for this interoperability is a passed conformance test of both devices. The scope is to specify common available procedures and definitions for conformance and/or interoperability testing of the IEC 62351-5 and the IEC 60870-5-7. The conformance test cases defined here are focused to verify the conformant integration of the underlying authentication, as specified in IEC 62351-5 and the IEC 60870-5-7, to protect IEC 60870-5- 101 and IEC 6870-5-104 based communications. This part of IEC 62351 deals with data and communication security conformance testing; therefore, other requirements, such as safety or EMC are not covered. These requirements are covered by other standards (if applicable) and the proof of compliance for these topics is done according to these standards. NOTE: The title of this normative was changed to 'Conformance test cases for IEC 62351-5 and IEC 60870-5-7' because the test cases defined in this document are specific to the security extension of IEC 60870-5-101 and IEC 60870-5-104 communication protocols. In this revision, all the resolution to the comments listed in the document 57/1914/CC were applied. As agrred with IEC Officers (see document 57/1914/CC), the clause 9 of this normative 114 ("Verification of IEC 62351-3 requirements") has been moved to a separate new normative, 115 the IEC 62351-100-3 (see document 57/1928/NP). The present note will be removed in the 116 next revision (TS) of this normative
