Multi-mirror design and implementation of virtual machine based on fine granularity data separation and fusion Gailing Guo Kai Shinili in order to conserve storage space and facilitate system upgrades, separating the system and user data from virtual machine mirroring is a common practice in cloud computing centers. The current mainstream use is to start the virtual machine with system mirroring, and then to mount the user data as disk, but this coarse-grained fusion method results in the data separation to the user, while the user data cannot cover the system data and the system lacks flexibility. For these issues, by analyzing the system mirroring and user mirroring the start and use of the principle of ...

Design and implementation of cloud computing identity management model based on trust Li Ying wo Zhouzhengi Li Huapo with the development of cloud computing, identity management problem has aroused great concern in the industry. The identity authentication mechanism based on group signature ensures that the cloud service provider cannot backtrack the user's identity information through the outsourced data and is widely used in the identity management of cloud computing environment, but it cannot prevent the malicious user from illegally accessing the cloud service. In view of this shortcoming, the existing identity management model is improved, and the Trust Management and group signature mechanism are combined to design a trust based identity management model. This model first calculates the ...
