Trusted Systems 
First International Conference, INTRUST 2009, Beijing, China, December 17-19, 2009. Proceedings

This volume contains the 16 papers presented at the INTRUST 2009 conf- ence, held in Beijing, China in December 2009. INTRUST 2009 was the ?rst international conference on the theory, technologies and applications of trusted systems. It was devoted to all aspects of trusted computing systems, incl- ing trusted modules, platforms, networks, services and applications, from their fundamental features and functionalities to design principles, architecture and implementation technologies. The goal of the conference was to bring academic and industrial researchers, designers and implementers together with end-users of trusted systems, in order to foster the exchange of ideas in this challenging and fruitful area. The program consisted of 3 invited talks and 20 contributed papers. The – vited speakerswere Wenchang Shi (Renmin Universityof China), David Wooten (Microsoft) and Scott Rotondo (Sun Microsystems). The ?rst speaker provided a paper, which is included in these proceedings. Special thanks are due to these speakers. The contributed talks were arranged with two main tracks, one devoted to academic aspects of trusted computing systems (addressed by these proce- ings), and the other devoted to industrial aspects. The contributed papers were selected out of 42 submissions from 13 countries. 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.
