Abstract:
A new method is put forward after analyzing the problem of traditional subjective trust valuation model,and the improved trust valuation model is applied to web service environment.Make the web service entity within environment can automatically renew with the increase of bargain number.Finally,simulation experiments show that the improved trust valuation model can better reflect the entity trust degree in web service.Keywords:

With the advent and proliferation of web services, quality of service serves as a benchmark to differentiate and select the services. Because trust has been regarded as an essential security relationship within a distributed network environment, quality evaluation of services from the viewpoint of trust presents a significant trend in decision support for selecting service over Internet. Unfortunately, the current research in the context of web services does not accurately reflect the randomness and fuzziness of trust, the basic issue in related research about trust. In this paper, we designed two kinds of trust cloud based on cloud model theory to describe the randomness and fuzziness of trust factors. Furthermore, a formalized calculation was provided to obtain the trust degree. To our knowledge, this is the first investigation into trust of web Service considering the integration of randomness and fuzziness, and applying the cloud model to quantitative evaluation of trust in the field of web services.

Huge risk exists in web service because of many cheatings and malicious acts in the open environment of internet with web services. So it’s a trend to build an effective trust mechanism based on web services. According to the characteristic of web service, a new trust evaluation model is proposed. In this trust model for web services reduces to trust degree of business and trust degree of customer evaluation. During implementing trust degree evaluation, it is necessary to think about the influence of service time, service result and malicious behavior to trust degree as pivot, and it designs a new web services architecture grounded on the new trust evaluation model, and explains the application of web services under the new architecture also. Simulation experimental results show the new trust evaluation model can distinguish the cheating and malicious act in web services.

In order to fairly evaluate the trust of a new Web service,in this paper,a dynamic trust starting model of Web service community is proposed.The secured trust value is gained from QoS value registered in the Web services’ registration center,and the experience trust value is acquired from own transaction records or other’s transaction records,which are willing to be shared.The actual trust value is the dynamic linear combination of two kinds of trust values.The weight of secured trust value is reduced dynamically with the increase of transaction times.Experimental results show that this model makes a new Web service competed with other Web services which exist long time and the users can be far away from fraud.

The network transactions based on trust have become increasingly important,but the trust evaluation model is not perfect in Web services,such as unknown identity of requestor,incomplete influence factors on trust degree and strong subjectivity.In view of the above questions,this paper proposes a trust enhanced comprehensive evaluation model for Web Services—WS-TECEM.On the basis of traditional model,WS-TECEM introduces the thought of trust relationship strength,first or second or third-hand view and the reliability of credit reference.The proposed model is much fine in trust granular and more powerful in trust index.The experimental result shows that the WS-TECEM can more fully and accurately measure the trust degree between service requestors and service providers.

In open and dynamic computing environment anyone can publish their own services, for instance on the Web by using Web services as building blocks. The service accessing based on internet requires that agents can coordinate with each other in a trustable and effective manner. In this paper we review the field of trust-based Web service access using a belief model of evidence theory which proposes a service trust model, which involves active trust of service provider and combines direct trust and recommendation trust. Also we are using a belief model of evidence theory with belief, disbelief and uncertainty functions. In this paper we have critically reviewed the field of trust-based Web service access. We propose a model for formal specification of the trust behavior of a service that a software developer binds an agreement and publishes with the service. Our proposed model expands the range of service source via active trust of object, which makes the access path to resource more flexible.

The utility of web services requires secure and constant services, but the existence of dishonest nodes services could damage the accessibility and availability in open networks. The existing trust models in open networks ignore a fact that object itself can provide trust information for services. This paper proposes a service trust model, which involves active trust of service provider and combines direct trust and recommendation trust. Also we are using a belief model of evidence theory with belief, disbelief and uncertainty functions. Our proposed model expands the range of service source via active trust of object, which makes the access path to resource more flexible.

Internet affects modern daily life with its technological innovation and rapid change. Trust plays an important role in the Internet world; however, a trust relationship between the buyer and seller is abstract and difficult to quantify. In this study, we conduct literature analysis, discussing trust models provided by many scholars. Thereafter, we design new architecture regarding the trust model. When using the Internet, both buyer and seller seek services with a higher trust level. For this study, we divided the trust model into five parts: trust belief, trust creation, trust process, trust allocation, and trust enforcement. At the end of this research, we applied the trust model to develop web service to show users' evaluation of trust value and scope of sellers in the online auction website.

To enhance the credibility of Web service composition,Pi-calculus based formal verification of trust Web service composition is proposed.Trust Web service composition is firstly defined Abstractly,and then the powerful behavioral theory of Pi-calculus is used to depict structure and internal interaction of trust Web service composition,and the mapping relation between trust entity and Pi-calculus is discussed.Automatic reasoner MWB is used to analyze and reason the trust Web service composition system,which is aimed at finding and correcting the faults before the execution of trust authentication of Web service composition and meet the users' demands on trust quality effectively.

In this paper, we propose a comprehensive trust management approach for Web services that covers the analysis/modelling of trust relationships and the development of trust management layer in a consistent manner. The specific characteristics of trust relationships in Web services are discussed. We introduce a separated trust management layer for Web services that can hold computing components for trust management tasks. A trust management architecture for Web services is proposed for building up the trust management layer. The proposed trust management architecture for Web services deals with trust requirements, trust evaluation, and trust consumption in Web services under a unified umbrella and it provides a solid foundation upon which may evolve the trust management layer for Web services.
