Abstract:

With the development of cloud computing technology, there are many services of network disks at home and abroad. They provide file storage, access, backup, sharing and other functions of file management to users. But at the moment, there are many problems in the network disk, such as poor security, inflexible sharing strategy, the lack of documentation and collaborative communication mechanism. In view of the above problems, this paper designed and implemented a cloud document secure storage management system based on IBE mechanism, which can enhance the security of users and provide online collaborative processing and other functions. The system adopts IBE mechanism to solve the tedious certificate management and private key secure distribution problems existing in PKI mechanism. It achieves the user documentation for the trusted share and secure storage. At the same time, the system enhance the user experience and realize the documents in each user cooperative work by rendering the PDF document browsing and the WebSocket communication mechanism, and greatly improving the work efficiency. Through the test, the system can meet the needs of the existing market in terms of functionality, security and efficiency.

Key words: cloud computing, cloud document, network disk, IBE mechanism, secure storage
