Embodiment Construction

[0061] The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.

[0062] refer to figure 1 , shows a structural block diagram of a system for obtaining a white-box lookup table of the present application, the system includes a client 01 and a server 02, there is a communication connection between the client 01 and the server 02, and the client 01 and the server 02 can interact with each other based on the communication connection.

[0063] The client 01 can obtain the information to be processed from the server 02 based on the communication connection, as well as the white-box lookup table that needs to be used when obtaining the processing information, and then process the information based on the white-box lookup table, for example, based on the white-box lookup The table decrypts the information, etc. The information includes video, audio, text, and images, and th...

Abstract

The embodiment of the invention provides a method and device for obtaining a white box lookup table. In the application, a server acquires a key related part in a white box lookup table, and the key related part comprises data generated based on a white box algorithm and a key; the server sends the key related part to the client; the client receives the key related part in the white box lookup table sent by the server; the client obtains a stored key irrelevant part in the white box lookup table from the client, and the key irrelevant part is sent to the client side by the server in advance and stored in the client; and the client generates a white box lookup table according to the key related part and the key unrelated part. Thus, when the client needs to process the information based onthe white box lookup table every time, compared with the prior art, the volume of the white box lookup table needing to be sent to the client by the server can be reduced, the data volume of the datain the white box lookup table needing to be sent to the client can be reduced, and therefore network resources can be saved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method, device, electronic equipment, storage medium and server for obtaining a white-box lookup table. Background technique [0002] At present, there are more and more videos on the network, and many users choose to watch the videos on the network on the client. For example, the user can control the client to send a video request to the video server on the network, and then the video server sends a request to the video server according to the request. The client sends the video, and then the client can play the video for the user to watch. [0003] In order to improve the security of the video during transmission, the video server can first encrypt the original video, and then send the encrypted video to the client. In this way, what the client receives is the encrypted video, and then the encrypted video can be decrypted to obtain the original video, and then the ...
