A Language for Trust Modelling
نویسندگان
چکیده
The computational trust paradigm supposes that it is possible to quantify trust relations that occur within some software systems. The paradigm covers a variety of trust systems, such as trust management systems, reputation systems and trust-based security systems. Different trust systems have different assumptions, and various trust models have been developed on top of these assumptions Typically, trust models are incomparable, or even mutually unintelligible; as a result their evaluation may be circular or biased. We propose a unified language to express the trust models and trust systems. Within the language, all trust models are comparable, and the problem of circularity or bias is mitigated. Moreover, given a complete set of assumptions in the language, a unique trust model is defined.

Probabilistic modelling and recursive bayesian estimation of trust in wireless sensor networks 381 Probabilistic modelling and recursive bayesian estimation of trust in wireless sensor networks
Wireless Sensor Networks closely resemble a human behaviour model, in which a number of nodes that have just met are able to communicate with each other based on mutual trust levels developed over a period of time. WSNs are characterised by their performance of an additional function to the traditional functions of an ad-hoc network, which is monitoring events and reporting data and, as such, t...

With the renewed interest in the field of second language learning for the knowledge of collocating words, research findings in favour of holistic processing of formulaic language could support the idea that these language units facilitate efficient language processing. This study investigated the difference between processing of a first language (L1) and a second language (L2) of congruent col...
متن کاملThe Socio-technical Security Requirements Modelling Language for Secure Composite Services
Composite services foster reuse and efficiency in providing consumers with different functionalities (services). However, security aspects are a major concern, considering that both service consumers and providers are autonomous and heterogeneous—thus, loosely controllable entities. When consumers provide information in order to be furnished some service, what happens to that information? Do se...
متن کاملAn analysis of the exponential decay principle in probabilistic trust models
Research in models for experience-based trust management has either ignored the problem of modelling and reasoning about dynamically changing principal behaviour, or provided ad-hoc solutions to it. Probability theory provides a foundation for addressing this and many other issues in a rigorous and mathematically sound manner. Using Hidden Markov Models to represent principal behaviours, we foc...
