Embodiment Construction
[0082] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0083] It can be understood that the terms "first", "second" and the like used in the present invention can be used to describe various elements herein, but these elements are not limited by these terms. These terms are only used to distinguish one element from another element. For example, a first client could be termed a second client, and, similarly, a second client could be termed a first client, without departing from the scope of the present invention. Both the first client and the second client are clients, and may be the same client or different clients.

The invention relates to a data transmission method and system, and a terminal. The method comprises the following steps: loading an encryption and encryption module provided by a third party, initiating a secret key service authentication request for a third-party server through an encryption transmission channel, and receiving a secret key which is provided by the third party and is returned after the third-party server successfully carries out authentication on the encryption and decryption module; obtaining a data plaintext, and encrypting the data plaintext into data cryptograph by use of the secret key which is provided by the third party and is obtained in advance; and sending the data cryptograph. According to the data transmission method and system, the data plaintext is encrypted into the data cryptograph by use of the secret key provided by the third party for sending, such that the possibility that the secret key is leaked in a data transmission process or a server employs its own secret key to decrypt the data cryptograph to obtain the data plaintext when forwarding the secret key is avoided, the data transmission security is improved, obtaining of the secret key also requires the authentication, and the data decryption security is improved.
Description
technical field [0001] The present invention relates to computer communication technology, in particular to a data transmission method, system and terminal. Background technique [0002] Data transmission in traditional network services mainly uses direct transmission between the client and the client or transmission from the client to the client through the server. [0003] Clients negotiate keys with each other for data transmission, and the transmission process is not transmitted through a private encrypted channel, the key may be leaked, and the security of data transmission is low. [0004] When data is forwarded between clients through the server, the server provider may obtain the plain text of the data: [0005] 1. Data is transmitted in plain text; [0006] 2. The channel of data transmission has been encrypted, but the data is stored, processed or forwarded in plain text on the server; [0007] 3. The data transmission channel has been encrypted, and the data is...
