 Address Protected Neighbor Discovery for Low-power and Lossy Networks
                        draft-ietf-6lo-ap-nd-00

Abstract

   This document defines an extension to 6LoWPAN Neighbor Discovery.
   This extension is designed for low-power and lossy network
   environments and it supports multi-hop operation.  Nodes supporting
   this extension compute a Cryptographically Unique Interface ID and
   associate it with one or more of their Registered Addresses.  The
   Cryptographic ID (Crypto-ID) uniquely identifies the owner of the
   Registered Address.  It is used in place of the EUI-64 address that
   is specified in RFC 6775.  Once an address is registered with a
   Cryptographic ID, only the owner of that ID can modify the state
   information of the Registered Address in the 6LR and 6LBR.

1.  Introduction

   Neighbor discovery for IPv6 [RFC4861] and stateless address
   autoconfiguration [RFC4862] are together referred to as neighbor
   discovery protocols (NDP).  They are defined for regular hosts that
   have sufficient memory and computation capabilities.  These protocols
   are however not suitable for resource-constrained devices.
   Therefore, they require adaptation to work on resource-constrained
   hosts operating over a low-power and lossy network (LLN).  Neighbor
   Discovery optimizations for 6LoWPAN networks include simple
   optimizations such as a host address registration feature.  This
   feature uses the address registration option (ARO) which is sent in
   the unicast Neighbor Solicitation (NS) and Neighbor Advertisement
