This document updates the IPv6 over Low-Power Wireless Personal Area
Network (6LoWPAN) Neighbor Discovery (ND) protocol defined in RFCs
6775 and 8505. The new extension is called Address-Protected
Neighbor Discovery (AP-ND), and it protects the owner of an address
against address theft and impersonation attacks in a Low-Power and
Lossy Network (LLN). Nodes supporting this extension compute a
cryptographic identifier (Crypto-ID), and use it with one or more of
their Registered Addresses. The Crypto-ID identifies the owner of the
Registered Address and can be used to provide proof of ownership of
the Registered Addresses. Once an address is registered with the
Crypto-ID and a proof of ownership is provided, only the owner of
that address can modify the registration information, thereby
enforcing Source Address Validation.
This document is a product of the IPv6 over Networks of Resource-constrained
Nodes Working Group of the IETF.
This is now a Proposed Standard.
STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements. Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the
standardization state and status of this protocol. Distribution of this
memo is unlimited.
