    <pub:abstract><![CDATA[Computing today is moving away from the desktop, becoming diffused into our surroundings and onto
our personal digital devices. Moreover, ad-hoc networks such as Bluetooth provide for spontaneous connectivity
between computationally enabled devices within proximity to each other. In such pervasive computing
environments, users expect to access resources and services at any time from anywhere. This expectation
results in serious security issues, since devices are constantly interacting with others outside of their �home�
environments. We describe the security challenges in pervasive computing, explaining why traditional security
mechanisms fail to meet the demands of these environments. We use an agent-oriented paradigm to
model the interactions between computationally enabled entities in such dynamic environments, and present
an infrastructure that combines existing authentication features like Simple Public Key Infrastructure (SPKI)
with notions of policy driven interaction and distributed trust, in order to provide a highly flexible approach
for enforcing security policies in pervasive computing environments. We present an implementation of the
system on a variety of handheld/laptop devices using Bluetooth/802.11, and include an ontology to describe
principals, credentials and policies.]]></pub:abstract>
