Abstract

This document describes an extension to NHRP [1] which would allow

Mobile NHCs to perform a registration with and attach to an NHS in

their home LIS in an authenticated manner.

As described in this document, Mobile NHCs are NHCs which are not

configured with enough information to find a specific serving NHS in

their home LIS, but which have a mechanism to find an NHS (which may

or may not be a serving NHS) to which they will attach. As described

in [1], an NHC may attach to a 'surrogate' NHS by using a mechanism

such as an anycast address. In this case, the NHC may use the

surrogate NHS to send a NHRP Registration Request toward the NHC's

home LIS where a serving NHS resides. However, as defined in [1],

packet authentication is performed on a hop by hop basis. In the

mobile NHC case, it is not practical for the mobile NHC be in a

security relationship with every surrogate NHS, thus it is presumably

desirable to have some form of end to end only authentication for the

case of a mobile NHC's registration. This document describes an

authentication extension for NHRP which has such end to end only

semantics.

1. Introduction

The keywords MUST, MUST NOT, REQUIRED, SHALL, SHALL NOT, SHOULD,

SHOULD NOT, RECOMMENDED, MAY, and OPTIONAL, when they appear in this

document, are to be interpreted as described in [4].

This document describes an extension for Mobile NHCs to use when they

wish to register with their home LIS but initially connect to a non-

serving NHS to do so. The reader is encouraged to read [1] for more

details on the NHRP registration process.
