 Address Protected Neighbor Discovery for Low-power and Lossy Networks
                      draft-sarikaya-6lo-ap-nd-02

Abstract

   This document defines an extension of 6LoWPAN Neighbor Discovery for
   application in low-power and lossy networks.  The protocol is
   specified to be protected and to support multi-hop operation.  A node
   computes its Cryptographic, Unique Interface ID, and associates one
   or more of its Registered Addresses with that Cryptographic ID in
   place of the EUI-64 that is used in RFC 6775 to uniquely identify the
   interface of the Registered Address.  Once an address is registered
   with a Cryptographic ID, only the owner of that ID can modify the
   state in the 6LR and 6LBR regarding the Registered Address.

1.  Introduction

   Neighbor discovery for IPv6 [RFC4861] and stateless address
   autoconfiguration [RFC4862], together referred to as neighbor
   discovery protocols (NDP), are defined for regular hosts operating
   with wired/wireless links.  These protocols are not suitable and
   require optimizations for resource constrained, low power hosts
   operating over a low-power and lossy network (LLN) for low-power and
   lossy networks.  Neighbor Discovery optimizations for 6LoWPAN
   networks include simple optimizations such as a host address
   registration feature using the address registration option (ARO)
   which is sent in unicast Neighbor Solicitation (NS) and Neighbor
   Advertisement (NA) messages [RFC6775].  With 6LoWPAN ND [RFC6775],
   the ARO option includes a EUI-64 address to uniquely identify the
   interface of the Registered Address on the registering device, so as
   to correlate further registrations for the same address and avoid
   address duplication.  The EUI-64 address is not secured and its
   ownership cannot be verified.  It results that any device claiming
   the same EUI-64 address may take over a registration and attract the
   traffic for that address.
