 Address Protected Neighbor Discovery for Low-power and Lossy Networks
                      draft-sarikaya-6lo-ap-nd-01

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 with 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
