Abstract

The invention discloses a data transmission method and device. The data transmission method comprises the following steps: a server sends a first public key to a client; the server uses a first private key to decrypt a first message to obtain a target key, wherein the first public key and the first private key are a pair of keys, the first message is obtained through encrypting the target key withthe first public key by the client, and the target key is generated according to a random string sent by the server; the server receives a second message sent by the client, wherein the second message comprises the encrypted data obtained through encrypting first data with the target key by the client and second data, and the data to be transmitted includes the first data and the second data, wherein the first data is data that needs to be encrypted during the data transmission process, and the second data is data that does not need to be encrypted during the data transmission process; and the server uses the target key to decrypt the second message to obtain the data to be transmitted. The data transmission method and device solves the technical problem of low data transmission securityin the prior art.

Description

technical field [0001] The present invention relates to the field of data transmission, in particular to a data transmission method and device. Background technique [0002] At present, most websites and app interfaces use the http protocol to communicate, but the http protocol can easily monitor the content through the packet capture tool, and even tamper with the content. Even if the tampering of the content is prevented, the user in the network request packet is sensitive. Information is also easy to leak. In this case, a method of identity verification and content encryption with a high security factor is required to ensure the security of the http request process and ensure that the request received by the server is actually initiated by the user. And it has not been tampered with during transmission. [0003] In the prior art, there are mainly two data transmission methods for data transmission between the client and the server: [0004] The first data transfer metho...
