Abstract

The invention discloses a cloud storage system based on an edge server, belongs to a cloud storage and file encryption system, and solves a problem that a cloud terminal of a conventional cloud storage system cannot be trusted. The system comprises a cloud server, the edge server, and bottom layer equipment of a user terminal. The edge server carries out the encryption and metainformation processing of a file which needs to be transmitted by the bottom layer equipment to the cloud server, and then transmits the file to the cloud server. When the bottom layer equipment needs to download the file, the edge server downloads the file from the cloud server based on the user identity of the bottom layer equipment, and then transmits the file to the bottom layer equipment after decryption. The file metainformation and encryption information stored in the edge server are used for the encryption of the cloud server, and the edge server does not store the file before and after encryption, so as to guarantee the privacy and safety of the file of the cloud server. The edge server carries out the local management of the bottom layer equipment, and the grouped management improves the controllability of the system, and can avoid the embarrassment condition of excessive cloud loads caused by the connection of all bottom layer equipment to one cloud server.

Description

technical field [0001] The invention belongs to a cloud storage and file encryption system, in particular to a cloud storage system based on an edge server. Background technique [0002] Cloud storage system refers to a system that integrates a large number of different types of storage devices in the network through application software to work together through cluster applications, network technology or distributed file systems, and jointly provide data storage and business access functions to the outside world. , which inherits several characteristics of parallel computing, grid computing and distributed processing of cloud computing and expands on this basis. [0003] The proposal and wide application of cloud storage system breaks the space limitation of traditional storage methods and indirectly expands the storage capacity of devices. However, while users enjoy the services provided by cloud storage providers, they also lose absolute control over data: the files plac...
