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.
