stor:一种为移动互联网优化的可信在线存储系统的设计方案

Online storage subsystem is an important part of cloud computing systems. It provides not only high reliability and efficiency, but also easy scalability. Yet in order for users to confidently put their data, especially those containing crucial business secrets, onto the cloud, the cloud provider must gain the user's trust. However, current trust mechanisms, which require the user to grant cloud providers with permissions to do operations such as storing and modifying to the user's data, could not effectively prevent cloud providers from abusing these permissions. This paper presents a new mobile internet optimized trusted online storage schema, which not only improves current trust mechanisms by solving the afro mentioned problems, but is also optimized for the increasingly popular mobile internet usage scenario.
