Oxford UK in April 2009. Trust 2009 was the second international conference devoted to the
technical and socio-economic aspects of trusted computing. The conference had two main strands
one devoted to technical aspects of trusted computing (addressed by these proceedings) and the
other devoted to socio-economic aspects. Trust 2009 built on the successful Trust 2008
conference held in Villach Austria in March 2008. The proceedings of Trust 2008 containing
14 papers were published in volume 4968 of the Lecture Notes in Computer Science series.
ThetechnicalstrandofTrust2009contained15originalpapersonthedesign and application of trusted
computing. For these proceedings the papers have been divided into four main categories
namely: - Implementation of trusted computing - Attestation - PKI for trusted computing -
Applications of trusted computing The 15 papers included here were selected from a total of 33
submissions. The refereeing process was rigorous involving at least three (and mostly more)
independent reports being prepared for each submission. We are very grateful to our
hard-working and distinguished Program Committee for doing such an excellent job in a timely
fashion. We believe that the result is a high-quality set of papers some of which have been
signi?cantly improved as a result of the refereeing process. We would also like to thank all
the authors who submitted their papers to the technical strand of the Trust 2009 conference
all external referees and all the attendees of the conference.
