A New Approach to Access Control in Cloud

Abstract

Managing access control to data in an authorized and authenticated way is still one of the key challenges in cloud security. In a complex environment like cloud, data owners and cloud service providers need to continuously monitor all data access activities (who is accessing which data) in order to prevent unauthorized access. In this research, we have developed a dynamic access control system for cloud computing environment along with policy conflict resolution algorithm and several authorization validation processes. Our proposed system includes four models, namely access right model, policy model, access control management model and authorization model. The proposed system introduces a more efficient security scheme using an enhanced authorization scheme. Our experimental analysis depicts that the proposed model can efficiently deal with the access control management in the cloud environment.
