       LISP Control-Plane ECDSA Authentication and Authorization
                     draft-ietf-lisp-ecdsa-auth-00

Abstract

   This draft describes how LISP control-plane messages can be
   individually authenticated and authorized without a a priori shared-
   key configuration.  Public-key cryptography is used with no new PKI
   infrastructure required.

1.  Introduction

   The LISP architecture and protocols [RFC6830] introduces two new
   numbering spaces, Endpoint Identifiers (EIDs) and Routing Locators
   (RLOCs) which provide an architecture to build overlays on top of the
   underlying Internet.  Mapping EIDs to RLOC-sets is accomplished with
   a Mapping Database System.  EIDs and RLOCs come in many forms than
   just IP addresses, using a general syntax that includes Address
   Family Identifier (AFI) [RFC1700].  Not only IP addresses, but other
   addressing information have privacy requirements.  Access to private
   information is granted only to those who are authorized and
   authenticated.  Using asymmetric keying with public key cryptography
   enforces authentication for entities that read from and write to the
   mapping system.  The proposal described in this document takes
