Embodiment Construction

[0040] The present invention will be further described below with reference to the drawings and embodiments.

[0041] Such as figure 1 As shown, the embodiment of the present invention includes a cloud server, an edge server, and an underlying device. The cloud server is a public Tencent Cloud server. The edge server includes a first edge server and a second edge server. The first edge servers are the first to third edge servers. The bottom device provides services, and the second edge server provides services for the fourth to sixth bottom devices.

[0042] In this embodiment, the first edge server and the second edge server respectively use a desktop computer with a memory size of 16GB and a laptop computer with a memory size of 8GB. The first to sixth bottom devices are smart phones, and the device numbers are 861069039272250, 861069039272268, 861069039272270, 861069039272271, 861069039272272, 861069039272273.

[0043] The first and second edge servers each store an encryption a...

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, and specifically relates 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 through functions such as cluster applications, network technology or distributed file systems to work together to provide data storage and business access functions. , Which inherited several major characteristics of cloud computing, parallel computing, grid computing and distributed processing, and expanded on this basis. [0003] The proposal and widespread application of cloud storage systems broke the space limitations of traditional storage methods and indirectly expanded the storage capacity of devices. However, while users enjoy the services provided by cloud storage providers, they also lose absolute control over data: files pl...
