LISP Control-Plane ECDSA Authentication and Authorization
draft-ietf-lisp-ecdsa-auth-01
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
