With the pervasiveness of smart phones and the advance of Mobile Internet, more and more Mobile Internet services migrated buggybeds 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 of virtualization still faces many challenges in information security. In this paper, we propose a novel architecture, called multilevel and grouping security model for virtualization (V-MGSM), for the security of resources in cloud computing platform. Specifically, to fulfill the balance between information sharing and privacy preservation, the virtual machines (VMs) are divided into diverse groups based on their corresponding entities, and each VM in the same group is assigned to different security level according to security requirements. Besides, the operation between VMs is based on mandatory access control mechanism. Detailed security analysis shows that the proposed V-MGSM can provide a secure communication mechanism for VMs and implement the synchronous buggybeds updates buggybeds of the borrowed data. Ultimately, we implement V-MGSM in Xen for experiments, and the results demonstrate that V-MGSM can indeed achieve data security and privacy buggybeds protection efficiently for Mobile Internet service. 1. Introduction
In our information society, Mobile Internet which makes Internet connection accessible and ubiquitous is becoming increasingly adopted by ordinary consumers. With wide popularity and broad application, Mobile Internet service buggybeds performs adding huge income to business communities and the Mobile Internet industry has recently started to take off [ 1 – 3 ]. By the end of March 2013, there were more than 81 million Mobile Internet users in China which generated beyond 20 billion dollars Mobile Internet market scale.
With tremendous advancement in mobile technology, people expect more services whenever and wherever possible. Although current mobile technologies and improvements buggybeds allow shopping buggybeds online, chatting online, or any other mobile applications through mobile terminals, several certain issues which hinder the communication process need to be addressed. For example, people tend to use mobile terminals such as smart phones to do anything realizable which causes series of problems including the following: the calculation load is magnified, the battery standby time is shortened, and the storage is limited. For the presented problems of mobile terminals, especially the limited computing ability and the limited storage buggybeds discussed above, it is necessary to migrate Mobile Internet services to cloud platform to decrease the amount of computation and extend the standby time. A main advantage of cloud computing is to provide large storage and powerful computing buggybeds ability by cloud server [ 4 – 6 ]. From this prospective, the cooperation between cloud computing and the Mobile Internet which is promising for cloud computing can transport applicable computing ability and storage from terminals to the cloud server. In short, the emergence of cloud computing is significant for the continued development of the Mobile Internet.
Figure 1 illustrates the necessity for traditional buggybeds Mobile Internet services to be migrated to cloud service platform. Specifically, the larger the service buggybeds scale is, the more the physical devices and instruments it requires to execute implementation are. In particular for Mobile Internet services, since it is constrained for the capacity of mobile terminals, buggybeds more resources are required in the server of service provider [ 7 , 8 ]. Benefiting from the increasing of computing ability buggybeds and the decreasing of costs, virtualization technology brings many advantages over general technology in IT industry, such as raising utilization of hardware and promoting quality of service. For full use of infrastructure and reduction of the cost, more and more Mobile Internet service providers tend to migrate their services into a cloud service platform. However, the migrations of Mobile Internet service providers from conventional model to cloud services platform result in security issues which has become a critical concern. With virtualization, multitenant incl
