Secure isolation of cloud consumers legitimacy using fuzzy analytical hierarchy process (AHP)

Abstract

Cloud computing refers to a variety of services available over the internet that deliver computing functionalities from the service providers infrastructure. Their capabilities are deliberated as software and hardware components in the large repository. However, employing secure services is an indispensable issue in cloud computing. Notably, estimating the legitimacy of consumers is a vital hurdle in delivering services to genuine consumers. Hence, an approach for assessing the legitimacy of cloud consumers is suggested in this paper using Fuzzy Analytical Hierarchy Process (AHP). This model regularly monitors the legitimacy of cloud consumers and ranks them using different scales. Then it constructs a judgment matrix based on which the legitimacy indices of cloud consumers are estimated. Experiments have been conducted to prove the appropriateness of our approach and the results are shown.
