This book constitutes the refereed proceedings of the 28th IFIP WG 6.1 International Conference on Formal Techniques for Networked and Distributed Systems, FORTE 2008, held in Tokyo, Japan, in June 2008 co-located with TestCom/FATES 2008.

The 19 revised full papers and 1 revised short paper presented together with 1 invited talk were carefully reviewed and selected from 44 submissions. The papers cover new approaches, concepts and experience in the application of formal methods for the specification and verification of distributed systems and applications. Special focus is put on ubiquitous, grid, and mobile computing systems, and also on the application of formal techniques to service oriented architectures as well as security issues in networked systems. The papers are organized in topical sections on abstraction, verification, specification framework, application, theory, and reliability of networked systems.
