RFC5909 - Securing Neighbor Discovery Proxy: Problem Statement
Neighbor Discovery Proxies are used to provide an address presence on a link for nodes that are no longer present on the link. They allow a node to receive packets directed at its address by allowing another device to perform Neighbor Discovery operations on its behalf.
Neighbor Discovery Proxy is used in Mobile IPv6 and related protocols to provide reachability from nodes on the home network when a Mobile Node is not at home, by allowing the Home Agent to act as proxy. It is also used as a mechanism to allow a global prefix to span multiple links, where proxies act as relays for Neighbor Discovery messages.
Neighbor Discovery Proxy currently cannot be secured using Secure Neighbor Discovery (SEND). Today, SEND assumes that a node advertising an address is the address owner and in possession of appropriate public and private keys for that node. This document describes how existing practice for proxy Neighbor Discovery relates to SEND. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6273 - The Secure Neighbor Discovery (SEND) Hash Threat Analysis
This document analyzes the use of hashes in Secure Neighbor Discovery (SEND), the possible threats to these hashes and the impact of recent attacks on hash functions used by SEND. The SEND specification currently uses the SHA-1 hash algorithm and PKIX certificates and does not provide support for hash algorithm agility. This document provides an analysis of possible threats to the hash algorithms used in SEND. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6494 - Certificate Profile and Certificate Management for SEcure Neighbor Discovery (SEND)
SEcure Neighbor Discovery (SEND) utilizes X.509v3 certificates for performing router authorization. This document specifies a certificate profile for SEND based on resource certificates along with extended key usage values required for SEND. [STANDARDS-TRACK]
RFC6495 - Subject Key Identifier (SKI) SEcure Neighbor Discovery (SEND) Name Type Fields
SEcure Neighbor Discovery (SEND) defines the Name Type field in the ICMPv6 Trust Anchor option. This document specifies new Name Type fields based on certificate Subject Key Identifiers (SKIs). [STANDARDS-TRACK]
RFC6496 - Secure Proxy ND Support for SEcure Neighbor Discovery (SEND)
SEcure Neighbor Discovery (SEND) specifies a method for securing Neighbor Discovery (ND) signaling against specific threats. As defined today, SEND assumes that the node sending an ND message is the owner of the address from which the message is sent and/or possesses a key that authorizes the node to act as a router, so that it is in possession of the private key or keys used to generate the digital signature on each message. This means that the Proxy ND signaling performed by nodes that do not possess knowledge of the address owner's private key and/or knowledge of a router's key cannot be secured using SEND. This document extends the current SEND specification in order to secure Proxy ND operation. This document defines an Experimental Protocol for the Internet community.
