Research on Resource Allocation Scheme Based on Access Control in Cloud Computing Environment

摘要

To solve the problem that traditional resource allocation scheme does not take influence of cloud user behavior on resource allocation into consideration and has a static authorization process, this paper proposes resource allocation scheme based on access control (RASBAC), which introduces behavior trust into authorization process. This paper designs a calculation algorithm of behavior trust based on fuzzy analytic hierarchy process and presents a novel dynamic permission adjustment mechanism. Experimental results show RASBAC provides the basis for allocating resources dynamically and reasonably to cloud users with different behavior performances in cloud computing system, improves the utilization ratio of cloud computing resources and protects the security of the cloud computing environment.
