Abstract

The invention discloses a data storage and sharing system, comprising a first terminal, a cloud server and a second terminal, wherein the first terminal is used for encrypting main keys and file names to generate a symmetrical sub-key set, then encrypting files to be encrypted by using symmetrical sub-keys to generate an encrypted file set, and uploading the encrypted file set; the second terminal is used for downloading a target encrypted file from the cloud server, and sending a requested mail to a target mail address; the first terminal is further used for, when a user agrees with sharing files, sending the encrypted target symmetrical sub-keys to the second terminal via a mail, and when the user does not agree with sharing, replying a rejection instruction via a mail; and the second terminal is further used for, after receiving the encrypted target symmetrical sub-keys, decrypting the encrypted target symmetrical sub-keys to obtain the target symmetrical sub-keys, and decrypting the target encrypted file by using the target symmetrical sub-keys to obtain a decrypted file, thus completing file sharing. The system can improve the data storage and sharing security.

Description

technical field [0001] The invention belongs to the technical field of computers, and more specifically relates to a data storage and sharing system. Background technique [0002] With the rise and popularization of the concept of cloud computing, the application of cloud storage technology extended and derived from the concept of cloud computing is becoming more and more extensive. Cloud storage refers to a system that integrates various types of storage devices in the network through application software to work together through cluster applications, grid technology, or distributed file systems to jointly provide data storage and business access functions. Therefore, the purpose of saving storage space can be achieved. To put it simply, cloud storage is an emerging solution that puts storage resources on the cloud for users to access. Users can connect to cloud storage servers through any network-connected device to store data at any time and anywhere. fetch operation. ...
