    Abstract
    Service-based software can be exploited by potentially untrustworthy service requestors while providing services. Given that, it is

    important to identify, analyze the trust relationships between service providers and requestors, and incorporate them into the

    service-based software. Treating trust as a nonfunctional requirement (NFR) during software development and monitoring allows

    clarifying these relationships and measuring the trustworthiness of service requestors. This analysis is facilitated by incorporating

    trust scenarios and trust models into the software. A trust scenario describes a trust relationship between interested parties based on a specific context. A trust model provides trust equations to measure the trustworthiness of service requestors based on the analysis of service-based interactions. Although much research has been devoted to monitor service quality, to date, no approach has been proposed

    to develop and automatically monitor service providing software from trust perspectives.

    In this thesis, we propose a trust-aware service-based software development framework which utilizes our proposed Unified Modeling

    Language (UML) extension called UMLtrust (UML for trust scenarios)to specify the trust scenarios of a service provider and

    incorporates our developed trust model called CAT (Context-Aware Trust) into the software to calculate the trustworthiness of service

    requestors. The trust scenarios are converted to trust rules to monitor service-based interactions. A service requestor is penalized for the violation of a trust rule and rewarded when no rule is violated. The trustworthiness of the requestor is then calculated (using the equations of CAT) based on the current request, outcomes of previous requests, and recommendations from other service providers. A trust-based service granting algorithm is presented to decide whether a service requestor should be granted the requested service. A trust monitoring architecture is presented which is

    assumed to reside in each service provider. The monitor uses trust rules from UMLtrust specifications and trust equations from CAT to analyze service-based interactions. The incorporation of the monitor into a provider makes it trust-aware. A trust monitoring algorithm is provided to analyze interactions and make decisions at run-time. A prototype of a file sharing service-based grid is implemented to evaluate the applicability of our framework that confirms the effectiveness of the framework.
