The 4th International Conference on Trust Management (iTrust'2006), to be held on 16-19 May 2006 in Pisa, Italy, looks at trust from multidisciplinary perspectives: economic, legal, psychology, philosophy, sociology, as well as information technology.

Building upon the work of the IST iTrust Working Group and the success of the three previous iTrust International conferences, the aims of iTrust'2006 are to attract a critical mass of experts from industry, government, and academia with a keen interest in the area of trust management. The goals are:

• To facilitate the cross-disciplinary investigation of fundamental issues underpinning computational trust models by bringing together expertise from technology oriented sciences, law, philosophy and social sciences.
• To facilitate the emergence of widely acceptable trust management processes for dynamic open systems and applications.
• To facilitate the development of new paradigms in the area of dynamic open systems which effectively utilize computational trust models.
• To facilitate the integration of new trust management paradigms and emerging architectures for Grid computing and Virtual Organizations.
• To help the incorporation of trust management elements into existing standards.

General Chairs of the conference are Fabio Martinelli, IIT-CNR, Italy and Fabio Massacci, University of Trento, Italy.
