V-MGSM: A Multilevel and Grouping Security Virtualization Model for Mobile Internet Service

Abstract EN

With the pervasiveness of smart phones and the advance of Mobile Internet, more andmore Mobile Internet services migrated to the cloud service platform for better user experience.

As one of the most indispensable components of the cloud computing infrastructure,virtualization technology has attracted considerable interest recently.

However, the flourish ofvirtualization still faces many challenges in information security.

In this paper, we propose anovel architecture, called multilevel and grouping security model for virtualization (V-MGSM),for the security of resources in cloud computing platform.

Specifically, to fulfill the balancebetween information sharing and privacy preservation, the virtual machines (VMs) are dividedinto diverse groups based on their corresponding entities, and each VM in the same group isassigned to different security level according to security requirements.

Besides, the operationbetween VMs is based on mandatory access control mechanism.

Detailed security analysisshows that the proposed V-MGSM can provide a secure communication mechanism for VMsand implement the synchronous updates of the borrowed data.

Ultimately, we implement V-MGSMin Xen for experiments, and the results demonstrate that V-MGSM can indeed achievedata security and privacy protection efficiently for Mobile Internet service.
