Abstract. In future wireless networks, mobility-related services, such as Candidate
Access Router Discovery, will play a significant role in realizing truly ubiquitous,
seamless connectivity. In order for these services to be realized, however, their par-
ticular security concerns must be addressed. Moreover, the security solution must
be flexible and highly configurable in order to meet the demands of inter-domain
roaming agreements. In this paper, we explore a number of alternatives and present
a general architecture, iARSec, that provides both authentication as well as explicit
authorization for services running between neighboring access routers.

1. Introduction
With the success of current cellular systems, mobile users have come
to expect ubiquitous, seamless access to telephone services. Cellular
systems have succeeded in providing seamless mobility due, in part,
to the heavily engineered architecture of the local access network. In
cellular access networks, a number of agents work in concert to track
