iTrust is an Information Society Technologies (IST) working group, which started on 1st of August, 2002. The working group is being funded as a concerted action/ thematic network by the Future and Emerging Technologies (FET) unit of the IST program. The aim of iTrust is to provide a forum for cross-disciplinary investigation of the application of trust as a means of establishing security and con?dence in the global computing infrastructure, recognizing trust as a crucial enabler for meaningful and mutually bene?cial interactions. The proposed forum is intended to bring together researchers with a keen interest in complementary aspects of trust, from technology-oriented disciplines and the ?elds of law, social sciences, and philosophy. Hence providing the c- sortium participants (and the research communities associated with them) with the common background necessary for advancing toward an in-depth underst- ding of the fundamental issues and challenges in the area of trust management in open systems. Broadly the initiative aims to: – facilitate the cross-disciplinary investigation of fundamental issues underp- ning computational trust models by bringing together expertise from te- nology oriented sciences, law, philosophy, and social sciences – facilitate the emergence of widely acceptable trust management processes for dynamic open systems and applications – facilitate the development of new paradigms in the area of dynamic open systems which e?ectively utilize computational trust models – help the incorporation of trust management elements in existing standards.

This volume contains the proceedings of DAIS 2008, the 8th IFIP International Conference on Distributed Applications and Interoperable Systems. The conf- ence was held in Oslo, Norway during June 4–6, 2008 as part of the DisCoTec (Distributed Object Techniques) federated conference, in conjunction with the 10th International Conference on Coordination Models and Languages (COOR- DINATION) and the 10th IFIP International Conference on Formal Methods for Open Object-Based Distributed Systems (FMOODS). The conference was sponsored by IFIP (International Federation for Information Processing) and was organized by the IFIP Working Group 6.1. Distributed applications and interoperable systems have become an integral part of everyday living and hence part of the socio-economic ecosystem of our humanenvironment.Withsuchpervasivedistributionofsoftwaresystemsacross a multitude of heterogeneous environments and user domains, distributed app- cations must support seamless provision of services, as well as service evolution and adaptability to ensure long-term sustainability. This support must go - yond the provision of individual services in isolation, towards systems in which such services can interoperate and be integrated into the everyday environment catering for the changing needs of their users.
