Title: Managing Trust in Distributed Agent Systems
Abstract: Software agent technology has attracted much attention for developing
various distributed systems, composed of autonomous agents interacting
with one another using particular mechanisms and protocols. Such systems provide
high-level reconfigurability, flexibility and robustness in dynamic environments,
and have applications in many areas. However, the great advantages
of distributed agent systems are often overshadowed by the challenges of providing
flexible and consistent security management for agent interactions in the
dynamic and heterogeneous computing environments. Trust, which is the belief
of an agent that the other agent will act or intend to act beneficially, is a basis
for secure distributed agent systems. In this paper, various major research issues
of managing trust among various entities are identified, and the approaches in
dealing with them are discussed. A framework for managing trust among various
entities in distributed agent systems is presented.

M¨¹ller-Schloer
Christian M¨¹ller-Schloer studied EE at the Technical University of Munich
and received the Diploma degree in 1975, the Ph. D. in semiconductor physics in
1977. In the same year he joined Siemens Corporate Technology where he worked in
a variety of research fields, among them CAD for communication systems,
cryptography, simulation accelerators and RISC architectures.
From 1980 until 1982 he was a member of the Siemens research labs in Princeton,
NJ, U.S.A. In 1991 he was appointed full professor of computer architecture and
operating systems at the University of Hannover. His institute, later renamed to
Institute of Systems Engineering ¨C System and Computer Architecture, engaged in
systems level research such as system design and simulation, embedded systems,
virtual prototyping, educational technology and, since 2001, adaptive and
self-organizing systems. He is author of more than 100 papers and several books.
He is one of the founders of the German Organic Computing initiative, which was
launched in 2003 with support of GI and ITG, the two key professional societies
for computer science in Germany. In 2005 he helped initiate the Special Priority
Programme on Organic Computing of the German Research Foundation (DFG).
Present projects deal, among others, with topics like quantitative emergence,
organic traffic control, adaptive communication stacks and ontology-based
self-organizing embedded systems.

Title: Organic Computing ¨C Emergence under
Control?
Abstract: Organic Computing has emerged as
a challenging vision for future information processing systems, based on the
insight that already in the near future we will be surrounded by large
collections of autonomous systems equipped with sensors and actuators to be
aware of their environment, to communicate freely, and to organize themselves.
The presence of networks of intelligent systems in our environment opens
fascinating application areas but, at the same time, bears the problem of their
controllability. Hence, we have to construct these systems - which we
increasingly depend on - as robust, safe, flexible, and trustworthy as possible.
In particular, a strong orientation of these systems towards human needs as
opposed to a pure implementation of the technologically possible seems
absolutely central. In order to achieve these goals, our technical systems will
have to act more independently, flexibly, and autonomously, i.e. they will have
to exhibit life-like properties. We call those systems ¡°organic¡±. Hence, an
¡°Organic Computing System¡± is a technical system, which adapts dynamically to
the current conditions of its environment. It will be self-organizing,
self-configuring, self-healing, self-protecting, self-explaining, and
context-aware.
The vision of Organic Computing and its fundamental concepts arose independently
in different research areas like Neuroscience, Molecular Biology, and Computer
Engineering. Self-organizing systems have been studied by mathematicians,
sociologists, physicists, economists, and computer scientists, but so far almost
exclusively based on strongly simplified artificial models. Central aspects of
Organic Computing systems have been and will be inspired by an analysis of
information processing in biological systems. Nevertheless, the anticipated
first generations of organic computing systems will still be based on well-known
silicon technology. Their life-like properties will arise from opening up
certain degrees of freedom in the functionality of technical application systems
and by the transfer of organisational concepts observable in natural systems
into their system architecture.
First steps towards adaptive and self-organizing computer systems are already
being undertaken. Adaptivity, reconfigurability, emergence of new properties,
and self-organisation are topics in a variety of research projects. The aims of
OC have become strategic goals of prominent IT companies like IBM, Sun, Bosch,
DaimlerChrysler, or Siemens-Fujitsu. The recently approved priority research
program of the German Science Foundation (DFG) addresses fundamental challenges
in the design of organic computing systems; its objective is a deeper
understanding of emergent global behaviour in self-organising systems and the
design of specific concepts and tools to support the construction of organic
computing systems for technical applications.
For a technical exploitation, however, it must be understood that there exists a
fundamental contradiction between classical top-down designs and freely emergent
bottom-up systems: the problem of ¡°controlled emergence¡±. The solution seems to
lie in the middle: Dedicated observer/controller layers (or MAPE cycles) must
take control of emergent subsystems without stifling their creativity.
The keynote will give a brief overview of the German and European research
activities in the field of Organic Computing and introduce observer/controller
architectures as a basic architectural template to solve the ¡°controlled
emergence¡± problem. Part of the fascination exerted by this new research field
is due to the broad interpretability of the terms ¡°emergence¡± and
¡°self-organization¡±. The presentation will try to reduce the somewhat fuzzy
meanings of these terms to a technically usable interpretation. Based on such a
clarified terminology it will discuss an Organic Computing roadmap, which should
help to classify different types of self-organizing systems.

Title: Transparent Computing: A New Paradigm for Pervasive Computing
Abstract: Mark Weiser said in 1991: ¡°the most profound technologies are
those that disappear. They weave themselves into the fabric of everyday life
until they are indistinguishable from it.¡± Due to the research and technological
advances in embedded systems, wireless networks, mobile computing, distributed
computing and agent technologies, etc, ubiquitous or pervasive computing is
emerging rapidly as an exciting new disciple to provide computing and
communication services all the time, everywhere. Its systems are now invading
every aspect of our life. Currently there are many ongoing academic and
industrial initiatives, but they are still too far to achieve the vision Mark
Weiser described.
In the keynote talk, a new computing paradigm, i.e., Transparent Computing
paradigm, to support ubiquitous/pervasive computing, will be presented. We will
start with a comprehensive survey and analysis on traditional paradigms, in term
of complexity, high TOC, weak security and hard to use. We argue, not
user-friendly, i.e., users can not get services from computer easily, is one of
the main reasons why Mark Weiser¡¯s vision can not be realized.
Accordingly, a proposed and developed software platform, which runs in a network
environment and operates at the assembler instruction level, is described fully.
This platform lets users choose heterogeneous OSes and applications upon them on
demand from centered simple servers, similar to choose different TV channels in
daily life. The platform will be further illustrated by the concepts, the
architectures and some key technologies. A pilot system implemented based on
such transparent computing paradigm will also be given in details.
