              Trusted Computing: Open, Closed, or Both?

Abstract:
How might a next-generation computer system help us to decide, remember,
and change our minds about whom and what we trust, to do what, under
which circumstances?

Our question has been partly answered by a bewildering array of
competing architectures, including SELinux and Microsoft's Trustworthy
Computing Initiative. In this seminar I attempt to shed some light on
the architectural competition.

My analysis is based on an examination of three use cases (email,
business-to-business e-commerce, and digital rights management), with
respect to three types of trust relationships: hierarchical trust, peer
trust, and bridging trust. Open-source and closed-source design
methodologies have differing strengths and weaknesses in supporting each
of these three relationship types, suggesting that the most successful
trusted computer systems of the future will be designed by a hybrid
methodology.

Biographical note:
Dr Clark Thomborson has served as a Professor of Computer Science at the
University of Auckland, New Zealand, since 1996.  His prior academic
positions were at the University of Minnesota, and at the University of
California at Berkeley, with consultancies or temporary positions at
MIT, Microsoft Research (Redmond), InterTrust, IBM Yorktown, IBM
Almaden, Institute for Technical Cybernetics (Slovakia), and Xerox PARC.

He gained several years of commercial experience in the USA as a systems
integrator at Digital Biometrics Inc (now Identix), LaserMaster Inc, and
Nicolet Instrument Corp (now Thermo Electron).

Under his birth name Clark Thompson, he was awarded a PhD in Computer
Science from C-MU and a BS (Honors) in Chemistry from Stanford.  He has
published more than 90 refereed papers on topics in software security,
computer systems performance analysis, VLSI algorithms, data
compression, and connection networks.
