Problems solved by technology
Since the terminal devices of the shared users who have been released from the sharing relationship still have the shared key before the sharing relationship was released, once the data storage server is compromised, it is still possible to view and decrypt the uploaded data of the users who shared the data after the sharing relationship was released. Shared data, resulting in low security of shared data

Embodiment Construction
[0105] figure 1 It is a schematic structural diagram of the data sharing system of this application. Such as figure 1 As shown, the data sharing system provided in this embodiment is used to provide users with data sharing services, and specifically includes: at least two terminals 101 , a sharing server 102 , a key server 103 and a data storage server 104 .
[0106] In the embodiment of this application, after the user binds the terminal 101 and accesses the Internet 105, the user can access the sharing server 102, the key server 103 and the data storage server 104 in the data sharing system through the bound terminal 101, and enjoy Data sharing service. Optionally, the user may log in and bind the terminal 101 through user identification information (for example: account number and password). Wherein, the terminal 101 may specifically be a desktop computer (Computer), a notebook computer (Notebook), a tablet computer (Pad), a smart phone (Smart Phone), a smart watch (Smar...

The present application provides a shared data processing method, communication device and communication equipment. The method includes: the first terminal obtains the first shared data designated by the first user; the first terminal sends the first identification information and the first shared data encrypted by the first shared key to the data storage server; if the first user is detected When the shared user in the specified sharing group changes, the first terminal calculates the second shared key according to the first shared key; the first terminal acquires the second shared data specified by the first user; the first terminal sends the data to the data storage server The second identification information and the second shared data encrypted by the second shared key. Therefore, the security of the shared data is improved, and it is ensured that the shared user who is deleted from the sharing group cannot obtain the second shared data specified and uploaded by the first user after the sharing relationship is released.
Description
[0001] This application claims the priority of the Chinese patent application with the application number 201810266990.1 and the application name "Shared Key Update Method, Device and System" submitted to the China Patent Office on March 28, 2018, the entire contents of which are incorporated herein by reference Applying. technical field [0002] The present application relates to the field of security technology, and in particular, the technical field of the present application relates to a shared data processing method, communication device and communication equipment. Background technique [0003] Data sharing is a common business form, which allows users with different terminals in different places to read the data shared by others and perform various operations, calculations and analyzes on the shared data. It is mostly used in photo sharing based on friend relationships, based on Colleague relationship document sharing, etc. Data sharing requires users who share data ...
