A majority of the grid implementations tend to address the safety concerns by authenticating the users, hosts and their interactions in an appropriate manner. Sophisticated and secured resource management systems are mandatory for the efficient and beneficial utilization of grid computing services. The wide range of selection and the high degree of strangeness have been identified as the problem factors in the secured selection of grid. Efficient resource allocation and utilization can not be achieved with the lack of a higher degree of confidence relationship. Owing to the large scale applications in e-commerce and on-line communities, reputation mechanisms have been widely acknowledged as one of the significant techniques supporting distributed application and system safety lately. We have proposed a novel approach in this paper that is aimed at providing trust and reputation aware security for resource selection in grid computing. In this approach, the self-protection capability and reputation weightage of an entity is utilized to obtain the Trust Factor (TF) value of that particular entity. In addition, jobs are probably allocated to entities that posses higher TF values. The proposed approach has been found to satisfactorily manage the increase in number of user jobs and grid entities. Extensive experimental evaluation of the performance shows that ascertaining grid entities intended towards the secured execution of the job with the aid of the proposed approach is competent and acceptable.

A number of grid implementations have been devised to deal with the security concerns by authenticating the users, hosts and their interactions in an appropriate fashion. Resource management systems that are sophisticated and secured are inevitable for the efficient and beneficial deployment of grid computing services. The chief factors that can be problematic in the secured selection of grid resources are the wide range of selection and the high degree of strangeness. Moreover, the lack of a higher degree of confidence relationship is likely to prevent efficient resource allocation and utilisation. In this paper, we present an efficient approach for the secured selection of grid resources, so as to achieve secure execution of the jobs. This approach utilises trust and reputation for securely selecting the grid resources. To start with, the self-protection capability and reputation weightage of all the entities are computed, and based on those values, the trust factor (TF) of all the entities are determined. The reputation weightage of an entity is the measure of both the user's feedback and other entities' feedback. Those entities with higher TF values are selected for the secured execution of jobs. To make the proposed approach more comprehensive, a novel method is employed for evaluating the user's feedback on the basis of the existing feedbacks available regarding the entities. This approach is proved to be scalable for an increased number of user jobs and grid entities. The experimentation portrays that this approach offers desirable efficiency in the secured selection of grid resources.
