This volume contains the post-proceedings of the third edition of the Int- national Symposium on Trustworthy Global Computing (TGC 2007), held in Sophia-Antipolis,France,November 5-6,2007,andtutorialpapersofthe foll- ing Workshop on the Interplay of Programming Languages and Cryptography, held in Sophia Antipolis, November 7, 2007. TheSymposiumonTrustworthyGlobalComputingisaninternationalannual venue dedicated to safe and reliable computation in global computers. It focuses on providing tools and frameworks for constructing well-behaved applications and for reasoning about their behavior and properties in models of computation that incorporate code and data mobility over distributed networks with highly dynamic topologies and heterogeneous devices. This volume starts with an invited paper from Martin Hofmann. It then - cludes the revised versions of the 19 contributed papers; these versions take into accountboth the referee's reports andthe discussions that took place during the symposium. The Program Committee selected 19 papers from 48 submissions. Every submission was reviewed by at least three members of the ProgramC- mittee.In addition, the Program Committee sought the opinions of additional referees, selected because of their expertise on particular topics. We are grateful to Andrei Voronkov for his EasyChair system that helped us to manage these discussions. We would like to thank the authors who submitted papers to the conference, the members of the ProgramCommittee, and the additional revi- ers for their excellent work. We would also like to thank the invited speakers to TGC 2007, Andrew D. Gordon, Martin Hofmann, and Je? Magee.
