Abstract

   This document specifies use profiles for the application of the
   simple group keying protocol (SGKP) to multi-destination TRILL
   Extended RBridge Channel message security (RFC 7978) and TRILL over
   IP packet security (draft-ietf-trill-over-ip).

1. Introduction

   This document specifies use profiles for the application of the
   simple group keying protocol (SGKP) [SGKPrfc] to the case using DTLS
   [RFC6347] formatted TRILL [RFC6325] [RFC7780] Extended RBridge
   Channel message security [RFC7178] [RFC7978] and to the case of using
   IPsec formatted TRILL over IP [TRILLoverIP]. It is anticipated that
   there will be other uses for this group keying protocol.

1.1  Terminology and Acronyms

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in [RFC2119] [RFC8174]
   when, and only when, they appear in all capitals, as shown here.

   This document uses terminology and acronyms defined in [RFC6325] and
   [RFC7178].  Some of these are repeated below for convenience along
   with additional new terms and acronyms.

      Data Label - VLAN or FGL.

      DTLS - Datagram Transport Level Security [RFC6347].

      FGL - Fine Grained Label [RFC7172].

         which group keying (Section 2) is in use.

      GKs - Stations in a group other than GKd (Section 2).

      HKDF - Hash based Key Derivation Function [RFC5869].

      IS-IS - Intermediate System to Intermediate System [RFC7176].

      keying material - The set of a Key ID, a secret key, and a cypher
         suite.

      PDU - Protocol Data Unit.

      QoS - Quality of Service.

      RBridge - An alternative term for a TRILL switch.

      SHA - Secure Hash Algorithm [RFC6234].

      TRILL - Transparent Interconnection of Lots of Links or Tunneled
         Routing in the Link Layer.
