This book constitutes the thoroughly refereed post-proceedings of the 7th International Workshop on Formal Aspects of Security and Trust, FAST 2010, held as part of the 8th IEEE International Conference on Software Engineering and Formal Methods, SEFM 2010 in Pisa, Italy in September 2010. The 14 revised full papers presented together with one invited paper were carefully reviewed and selected from 42 submissions. The papers focus of formal aspects in security and trust policy models, security protocol design and analysis, formal models of trust and reputation, logics for security and trust, distributed trust management systems, trust-based reasoning, digital assets protection, data protection, privacy and id issues, information flow analysis, language-based security, security and trust aspects in ubiquitous computing, validation/analysis tools, web service security/trust/privacy, grid security, security risk assessment, and case studies.

This Festschrift was published in honor of Andre Scedrov on the occasion of his 65th birthday. The 11 technical papers and 3 short papers included in this volume show the many transformative discoveries made by Andre Scedrov in the areas of linear logic and structural proof theory; formal reasoning for networked systems; and foundations of information security emphasizing cryptographic protocols. These papers are authored by researchers around the world, including North America, Russia, Europe, and Japan, that have been directly or indirectly impacted by Andre Scedrov. The chapter "A Small Remark on Hilbert's Finitist View of Divisibility and Kanovich-Okada-Scedrov's Logical Analysis of Real-Time Systems" is available open access under a CC BY 4.0 license at link.springer.com.
