Trust matters profoundly for many dimensions of political life. In this article we focus on political trust: how the trust or mistrust citizens have toward the political process, politicians and government affects politics. Prior research has shown that political trust influences such crucial dimensions of politics as the basic legitimacy of government, political participation, voting behavior,...

Trust is essential for most social and business networks in the web, and determining local trust values between two unfamiliar users is an important issue. However, many existing approaches to calculating these values have limitations in various constellations or network characteristics. We therefore propose an approach that interprets trust as probability and is able to estimate local trust va...

Hardly any aspect of human relationships is more fundamental than trust. Luhmann (1979) writes “trust, in the broadest sense of confidence in one’s expectations, is a basic fact of social life.” Trust is multi-faceted, involving competency, reliance, and integrity and is the glue that ensures society acts coherently and with purpose. In its absence, conflict and contention reign, with social ac...

In this paper, we continue our line of research for defining an integrated framework for the specification and analysis of security and trust, aimed at providing the basis for the modeling and analysis of security and trust aspects of emergent dynamic coalitions (e.g., mobile ad hoc networks, peer to peer systems, web services). In particular, we consider two well-known languages: 1) the Role-b...

Reputation systems play an important role in many Internet communities. They allow individuals to estimate other individual’s behavior during interactions. However, a more privacy-friendly reputation system is desirable while maintaining its trustworthiness. This paper presents a fair anonymous submission and review system. The review process is reputation-based and provides better anonymity pr...

We demonstrate that implicit beliefs influence trust. In an experiment, we induced one of two types of implicit beliefs: entity beliefs about negotiation ability (a belief that negotiation ability is fixed over time), and incremental beliefs about negotiation ability (a belief that negotiation ability can change over time). We find that people induced with entity beliefs maintain trust in their...

Trusted time sources are required to insert time stamps in electronic documents. A signed and time stamped electronic document is equivalent to a traditional paper document and is legally recognized. Clock synchronization protocols of the sort provided by Network Time Protocol (NTP) do not satisfy all requirements to assure that a time source is trustworthy. This paper proposes the use of an ex...

Except for a couple of rigorous software certification schemes that are required for certain safety-critical software applications (e.g., RTCA DO178-B), there are no generally trusted software certification schemes. While there is no theoretical reason why these safety-critical standards could not be applied to all applications, there is a practical reason: cost. Estimates vary, but it is gener...
