Privacy preserved entrust mechanism in cloud computing environment

Cloud computing technology enables service to add special characteristics such as remote execution, service mobility and virtual workspace in a handheld device. However, it has a limitation on application areas for the reason that mobile applications distinctly need a help of the host computer. To eliminate those threats, hash chain based approaches are proposed [1][2]. However, it also has some restriction that a mobile device sends request messages to each server when the device needs a multi-entity co-operative work. Therefore, this paper introduces a concept of secure entrustment, which provides most near and trusted servers whenever your mobile devices want to use a trusted computing.
