approach to trust management, based on a simple language for specifying trusted actions and trust relationships. It also describes a prototype implementation of a new trust management system, called PolicyMaker, that will facilitate the development of security features in a wide range of network services

In this paper, we analyze the formation of trusting relationships among people through communication. To foster trusting relationships, individuals must disclose private and personal information. However, disclosing such information has both costs and benefits; therefore, both parties must decide

are scalable to software systems with millions or billions of lines of code. We propose a framework that enables the collection and analysis of many disparate types of information to be applied to the issue of software assurance. Trust relationship modeling enables stakeholders to decompose the overall

Abstract—In this paper, we discuss a general methodology for analysis and modeling of trust relationships in distributed computing. We discuss the classification of trust relationships, categorize trust relationships into two layers and provide a hierarchy of trust relationships based on a formal

without pre-existing trust relationships wish to pool their resources. This paper studies attacks aimed at preventing correct message delivery in structured peer-to-peer overlays and presents defenses to these attacks. We describe and eval-uate techniques that allow nodes to join the overlay, to maintain

relationships between individuals that are not directly connected in the network. Both algorithms are shown theoretically and through simulation to produce calculated trust values that are highly accurate.. We then present TrustMail, a prototype email client that uses variations on these algorithms to score

protection for privacy and trust. A trust establishment mechanism for web services must therefore ensure privacy and owner control at all times due to the subjectivity of trust relationships. This paper describes an indirect trust establishment mechanism to bridge and build new trust relationships from
