The paper deals with the phenomenal trust modelling. Required terms as trust, trust types, trust values and representation are mentioned. Fundamental description of phenomenal trust formation is presented as a form of impersonal trust which is complementary to interpersonal trust. Phenomenon is defined by the set of its possible exclusive values. The model describes the trust of a subject to pa...

With the emergence of the web of services and the semantic web, the need to find different methods of web service selection is gaining importance. Many efforts are focusing on the aspects of building the trust networks on the semantic web as well as agent-based models to utilize the trust in selecting the appropriate web service from a group of available services.The main direction of the resea...

This paper presents a certified confidence model which aims to ensure credibility for information exchanged among agents which inhabit an open environment. Generally speaking, the proposed environment shows a supplier agent b which delivers service for a customer agent a. The agent a returns to b a cryptographed evaluation r on the service delivered. The agent b will employ R as testimonial whe...

Pretty Good Privacy [3], or PGP, is a milestone in the history of cryptography, because for the first time it makes cryptography accessible to the wide mass of privacy hungry on-line public. PGP was created primarily for encrypting email messages using public or conventional key cryptography. The latter are used mainly to encrypt local files. With public key cryptography, PGP first generates a ...

Economic and social activity is increasingly reflected in operations on digital objects and network-mediated interactions between digital entities. Trust is a prerequisite for many of these interactions, particularly if items of value are to be exchanged. In this paper the probabilistic model and computational approaches found in some network reliability models are applied to modelling computat...

Probabilistic trust has been adopted as an approach to taking security sensitive decisions in modern global computing environments. Existing probabilistic trust frameworks either assume fixed behaviour for the principals or incorporate the notion of ‘decay’ as an ad hoc approach to cope with their dynamic behaviour. Using Hidden Markov Models (HMMs) for both modelling and approximating the beha...

In this paper we present a generic model of trust for electronic commerce. The basic components of the model are party trust and control trust. We argue that an agent’s trust in a transaction with another party is a combination of the trust in the other party and the trust in the control mechanisms for the successful performance of the transaction. The generic trust model can be used for the de...

The open and anonymous nature of peer-to-peer system makes it easy to be attacked and abused by some malicious nodes, so it is very important to establish a perfect trust mechanism in peer-to-peer environment. In this paper, we propose a novel group-based trust model in which the trust relationships between entities are divided into trust relationship in group and trust relationship between gro...

Article history: Accepted 25 September 2012 Available online xxxx Current approaches in sociotechnical systems consider trust to be either cognitive—referring to actors' mental models of each other—or technical—referring to an actor's trust of a technical artifact. In this paper, we take a more expansive view of trust: in addition to the cognitive, we also consider trust in the architectural se...
