Research and application of access control mechanism in cloud computing environment

University Li Shigang

Based on the research of traditional access control technology, this paper analyzes the application requirements of access control technology in cloud computing environment. Aiming at the problem of virtual machine security and privilege management in cloud computing environment, a security solution based on access control technology is proposed and implemented. The main work is as follows: 1. This paper studies the application status of the traditional access control technology, analyzes the application status of the access control technology in cloud environment, analyzes its characteristics and analyzes the new requirements under the cloud computing environment. 2. Security isolation for virtual machines and potential covert access problems between virtual machines. Based on the study of BLP, this paper presents a VBLP model for virtual environment, and proves the model. 3. Aiming at the problem of Administrator's authority in cloud environment, an access control scheme based on the thought of "separation of powers" is proposed and implemented. The access control scheme of the separation of powers minimizes the risk to the user resources caused by the malicious operation or misoperation of the administrator.
