Rule based trust evaluation using fuzzy logic in cloud computing

Abstract

Presently, the cloud computing is a regarded research both in scholars and enterprise, because of its unique features such as low expenditure, easy maintenance, flexibility, fast deployment and reliable service. However to administer cloud computing, improvement in academic, legal and institutional fields is necessary. Especially, the issue of trust is one of the biggest obstacles for the development of cloud computing. The high rate of accessibility and lack of absolute authenticity makes it unreliable and unsafe. The impact and destruction for the software and hardware cloud resources in cloud computing are worse than the current Internet users who use it to share resources. Therefore, questions like whether user behavior is trusted, how to evaluate user behavior trust is important in cloud computing and need to be answered. Mainly this paper discusses about the evaluation of user behavior trust, appraisement strategy and fuzzy logic, in the cloud computing.
