With the increase in interest in web based e-commerce, the amount of business that is transacted on-line and the explosion in the amount of services available, the ability to

environments such as those enabled by the semantic web and pervasive computing technologies. The presence of heterogeneous entities that
are neither pre-determined nor permanent, and the lack of central

These are connected to each other using both infrastructure-based as well as short-range ad hoc networks.

recent years.  On the one hand there are efforts to develop new access
control models to meet the policy needs of real world application
domains. In parallel, and almost separately, researchers have
developed policy languages for access control.  This paper is
motivated by the consideration that these two parallel efforts need to
develop synergy.  A policy language in the abstract without ties to a

Semantic Web applications. Current RDF stores have primarily
focused on efficiently storing and querying large volumes

  <description><![CDATA[Policies are being increasingly used for controlling the behavior of
complex multi-agent systems. The use of policies allows administrators to regulate
agent behavior without changing source code or requiring the consent or

sometimes encounter difficulties when applied to agents that act in pervasive
environments characterized by frequent and unpredictable changes. In such cases,

  <description><![CDATA[In this paper we describe a policy language designed
for pervasive computing applications that is based on deontic
concepts and grounded in a semantic language. The
pervasive computing environments under consideration are
those in which people and devices are mobile and use various
wireless networking technologies to discover and access
services and devices in their vicinity. Such pervasive
environments lend themselves to policy-based security due
to their extremely dynamic nature. Us...]]></description>

  <description><![CDATA[Policies guide the way entities within a domain act, by providing
rules for their behavior. Most of the research in policies is within a
certain application area, for example security for databases, and
there are no general specifications for policies. Another problem
with policies is that they require domain dependent information,
forcing researchers to create policy languages that are bound to the
domains for which they were developed. This prevents policy
languages from being flexib...]]></description>

  <description><![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 wit...]]></description>

  <description><![CDATA[Traditionally, stand-alone computers and small networks rely on user authentication and access control to provide security. These physical methods use system-based controls to verify the identity of a person or process, explicitly enabling or restricting the ability to use, change, or view a computer resource. However, these strategies are inadequate for the increased flexibility that distributed networks such as the Internet and pervasive computing environments require because such systems l...]]></description>

  <description><![CDATA[This paper discusses our infrastructure for handling distributed security and trust. It outlines a method for access control
across domains that handles complex inter domain trust relationships. We have developed a flexible representation of trust
information in Prolog, that can model permissions and delegations. We are currently working on modeling obligations,
entitlements, and prohibitions as well. This paper describes a scheme for restricting re-delegation without using a specific

  <description><![CDATA[As applications become more sophisticated, intelligent and function in open and dynamic en-vironments, they require greater degrees of decision making and autonomy.  A long range vision is for societies of intelligent, adaptive, autonomous agents, but even today, we find the new lev-els of autonomy emerging in infrastructures like the Web, Grid computing, and pervasive com-puting environments. These systems exchange information about services offered and sought and negotiate for information s...]]></description>

There is a growing diversity in the range of emerging network
applications such as social networking, online multiplayer games
etc.  and their expected network sup- port. Similarly, there is a
growing diversity in the properties and capabilities of the
underlying physical layer technologies ranging from copper wires,
optical fibers, and wireless...]]></description>

  <description><![CDATA[There has been growing interest in the use of policy-based governing
frameworks for management of a wide range of systems. These systems ranging
from simple and static to increasingly complex and dynamic have demanding
requirements that make the management of policies a complex task. Though tools
have been developed to facilitate policy frameworks, there is not much work in
policy development that meets the requirements of these policy-based
environments. Some of these requirements incl...]]></description>
