Abstract
With the development of cloud computing technology and the proliferation of the Internet of Things (IoT) terminals, more and more scenes need the collaboration of virtual machines and IoT terminals to resolve. However, there are many severe challenges on the security of virtual machines and IoT terminals. Based on Bell-LaPadula Model (BLP), a task-oriented multilevel cooperative access control scheme virtualization and reality BLP, named VR-BLP, is proposed. Specifically, tasks are created for each user of the platform and tasks and users are divided into multiple levels to provide more granularities to limit access between virtual machines and IoT terminals. Moreover, with network isolation cooperating with process isolation and shared memory isolation mechanisms, VR-BLP is implemented to enhance the security isolations between tasks. Performance evaluations show that VR-BLP enhanced the security of environment with virtualization and IoT without causing significant performance penalty.

Summary
Since it was created in 2006, cloud computing [1,2,3] has been growing more and more popular in today’s society. To address security challenges in cloud environment, many access control schemes are proposed, such as RBAC [8] and TBAC [9]. The hybrid platform could provide more kinds of services meeting the needs of their own business, saving their money and energies to maintain two kinds of systems For ordinary consumers, they could buy more flexible service according to their needs and budget. In order to construct a task-oriented secure isolation mechanism for environment with virtualization and IoT, a new multilevel cooperative access control scheme named VRBLP is proposed in this paper. (1) A task-oriented multilevel cooperative access control scheme for environment with virtualization and IoT, named VR-BLP, is proposed to enhance the security isolations between users and tasks.
