Embodiment Construction

[0036] The present invention proposes a method for realizing secure data transmission, such as figure 1 A flowchart for the method proposed by the present invention, including:

[0037] Step 101: Divide the data into multiple segments, store some segments directly, and encrypt and store the rest of the segments;

[0038] Step 102: the server receives the download request from the terminal, and sends unencrypted data segments to the terminal;

[0039] Step 103: The server receives the identity verification request sent by the terminal, performs identity verification on the terminal, and sends encrypted data segments to the terminal after passing the verification.

[0040] In the above step 103, the terminal may send an identity verification request to the server while playing the unencrypted data segment.

[0041] If the authentication of the terminal by the server fails, an authentication failure message may be sent to the terminal.

[0042] In order to cope with the delay ...

Abstract

According to an embodiment of the present invention, the method comprises: a server dividing data into a plurality of data segments, directly saving some of the data segments as unencrypted data segments, and saving the remaining data segments as encrypted data segments; the server receiving a download request from a terminal for downloading the data, and sending the unencrypted data segments to the terminal; and the server receiving an authentication request sent by the terminal, performing authentication on the terminal, and sending the encrypted data segments to the terminal after authentication has passed.

Description

technical field [0001] The present invention relates to the technical field of data security, in particular to a method, system, server and terminal for realizing secure data transmission. Background technique [0002] In the existing data security technology, the server stores completely encrypted data (such as video data, audio data, etc.), the client sends a download request to the server, and the server performs identity verification. If the verification is passed, the server sends back the decryption key of the current data to the client; finally, the PC client downloads the encrypted data from the server, and uses the decryption key received in the previous step to play while decrypting. [0003] Since the entire data is encrypted, the PC client can start playing only after obtaining the decryption key. In order to obtain the decryption key, multiple network interaction activities must be performed between the PC client and the server, including identity verification ...
