Embodiment Construction

[0073] Embodiments of the present invention provide a file sharing method and device. The first terminal uploads each encrypted file to the server for storage, and receives the URL corresponding to the location of each encrypted file returned by the server, and generates a URL corresponding to the location of the file to be shared. The key package of the shared key and URL, and provide the key package to the second terminal, the second terminal obtains the corresponding encrypted file through the URL in the key package, and uses the shared key pair in the key package The obtained encrypted file is decrypted. Through the above method, the first terminal does not need to modify the files already saved in the server when sharing files, and the process is simple, which can effectively improve the efficiency of file sharing.

[0074] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

Abstract

The present invention provides a file sharing method and apparatus, to solve a problem in the prior art that a process is cumbersome and inefficient because a file that has already been saved needs to be changed when a file is shared by using a cloud server. The method includes: uploading, by a first terminal, each encrypted file to a server for saving, and receiving a uniform resource locator (URL) that is returned by the server and corresponds to a location for saving each encrypted file; generating a key package that includes a shared key and a URL that correspond to a file to be shared; and providing the key package for a second terminal, so that the second terminal acquires a corresponding encrypted file by using the URL in the key package, and decrypts the acquired encrypted file by using the shared key in the key package. By using the foregoing method, during file sharing, the first terminal does not need to change a file that has already been saved on the server, so that a process is simple and file sharing efficiency can be effectively improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a file sharing method and device. Background technique [0002] At present, the application of cloud computing has become more and more extensive. Based on the existing cloud server, files can be saved and backed up for users. More and more users are also willing to upload their files to cloud servers for storage to save storage costs. [0003] In addition to saving files for users, the cloud server can also share files saved by one user with another user. [0004] In the prior art, the method for cloud server to share files is as follows: user A packs 1000 files into a file package and encrypts it, and uploads the encrypted file package to the cloud server for storage. 100 files are shared with user B, then user A first retrieves the encrypted file package from the cloud server and decrypts it, takes out 1000 files in the encrypted file package, and then packs t...
