                     YANG Data Model for Key Chains

Abstract

   This document describes the key chain YANG data model.  Key chains
   are commonly used for routing protocol authentication and other
   applications requiring symmetric keys.  A key chain is a list
   containing one or more elements containing a Key ID, key string,
   send/accept lifetimes, and the associated authentication or
   encryption algorithm.  By properly overlapping the send and accept
   lifetimes of multiple key chain elements, key strings and algorithms
   may be gracefully updated.  By representing them in a YANG data
   model, key distribution can be automated.
