Embodiment Construction

[0231] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0232] Such as figure 1 As shown, a cloud storage system security assurance system of the present invention includes a client module, a storage module, an audit module and a security management module, and the client module is connected to the storage module, the security management module and the audit module respectively. terminal module;

[0233] The client module accepts the user's login and registration request, and accesses the storage terminal, the audit terminal and the security management terminal as a user agent; sends a data request to the storage terminal, and verifies the storage terminal read operation evidence and the storage terminal write operation evidence returned by the storage terminal ; Send evidence storage request and audit request to the audit terminal; send user registration request and user login request to the security manag...

Abstract

The invention discloses a cloud storage safety-ensuring method and a system of the cloud storage safety-ensuring method, and belongs to the technical field of computer storage and information security. The cloud storage safety-ensuring method and the system of the cloud storage safety-ensuring method solve the problem that an existing cloud storage system is short of safety assurance. The cloud storage safety-ensuring method comprises a client terminal process, a storage end process, an auditing end process and a safety management end process. The cloud storage safety-ensuring system comprises a client terminal module, a storage end module, an audit end module and a safety management end module. The cloud storage safety-ensuring method and the system of the cloud storage safety-ensuring method adopt an evidence mode and a visit controlling mechanism based on attribution encryption, achieve high-efficiency extensible visit control, solve the problem that access control of a large amount of user visiting of a large amount of data is complex, provide safety assurance for the cloud storage system, and greatly reduce access control cost of the storage end due to the fact that the storage end only needs an access control tree of stored files.

Description

technical field [0001] The invention belongs to the technical field of computer storage and information security, and in particular relates to a cloud storage system security guarantee method and system thereof. Background technique [0002] With the rapid development of computer technology and network technology, the amount of information data has exploded exponentially. Data storage has developed from stand-alone storage and distributed storage to the current cloud storage. Cloud storage is a concept emerging at the same time as cloud computing. Cloud storage system is a virtualized and easy-to-expand storage resource pool, which is the storage part of cloud computing. Users use cloud storage system through cloud computing, and cloud storage system means that storage can be provided to users through the network as a service. For users, the cloud storage system does not refer to a specific device, but a collection of many storage devices and servers. When users use the clo...
