             Group Domain of Interpretation (GDOI) Protocol
                Support for IEC 62351 Security Services

Abstract

   The IEC 61850 power utility automation family of standards describes
   methods using Ethernet and IP for distributing control and data
   frames within and between substations.  The IEC 61850-90-5 and IEC
   62351-9 standards specify the use of the Group Domain of
   Interpretation (GDOI) protocol (RFC 6407) to distribute security
   transforms for some IEC 61850 security protocols.  This memo defines
   GDOI payloads to support those security protocols.

1.  Introduction

   Power substations use Generic Object Oriented Substation Events
   (GOOSE) protocol [IEC-61850-8-1] to distribute control information to
   groups of devices using a multicast strategy.  Sources within the
   power substations also distribute IEC 61850-9-2 sampled values data
   streams [IEC-61850-9-2].  The IEC 62351-9 standard [IEC-62351-9]
   describes key management methods for the security methods protecting
   these IEC 61850 messages, including methods of device authentication
   and authorization, and methods of policy and keying material
