GB/T 25320.6-2023 Power systems management and associated information exchange - Data and communication security - Part 6: Security for IEC 61850 1 Scope and object 1.1 Scope This document specifies messages, procedures, and algorithms for securing the operation of all protocols based on or derived from IEC 61850. Table 1 Scope of application to standards Number Name IEC 61850-8-1 Communication networks and systems for power utility automation - Part 8-1: Specific communication service mapping (SCSM) - Mappings to MMS (ISO/IEC 9506-1 and ISO/IEC 9506-2) and to ISO/IEC 8802-3 IEC 61850-8-2 Communication networks and systems for power utility automation - Part 8-2: Specific communication service mapping (SCSM)-Mapping to Extensible Messaging Presence Protocol (XMPP) IEC 61850-9-2 Communication networks and systems for power utility automation - Part 9-2: Specific communication service mapping (SCSM) - Sampled values over ISO/IEC 8802-3 IEC 61850-6 Communication networks and systems for power utility automation -Part 6: Configuration description language for communication in power utility automation systems related to IEDs The initial audience for this document is intended to be the members of the working groups developing or making use of the protocols listed in Table 1. For the measures described in this document to take effect, they shall be accepted and referenced by the specifications for the protocols themselves. This document is written to enable that process. The subsequent audience for this document is intended to be the developers of products that implement these protocols. Portions of this document may also be of use to managers and executives in order to understand the purpose and requirements of the work. 1.2 Namespace name and version This clause is mandatory for any IEC 61850 namespace (as defined by all parts of IEC 61850-7-1). The parameters which identify this new release of this namespace are: - Namespace version: 2020 - Namespace revision: A - Namespace name: “IEC 62351-6: 2020 A” - Namespace release: 1 The table below provides an overview of all published versions of this namespace. 1.3 Code Component distribution There is currently no code component scheduled for the code component downloading area. 2 Normative references The following referenced documents are indispensable for the application of this document.
