Abstract

The present application provides a data transmission method, device and system, the method comprising: generating an asymmetric key pair including a first public key and a first private key, and sending a data request carrying the first public key to a server; Receive the ciphertext and the second public key sent by the server, the second public key is the public key in the asymmetric key pair obtained by the server, and the asymmetric key pair obtained by the server also includes the first Two private keys, the ciphertext is information encrypted with the seed parameters used to generate offline payment codes using a shared key; the shared key is based on the second private key and the first public key, using a pre- The key generated by the set key agreement algorithm; according to the first private key and the second public key, use the key agreement algorithm to generate a shared key, and use the shared key to encrypt the ciphertext Decrypt to obtain the seed parameter. The application not only guarantees the security of data in the whole transmission process, but also improves the efficiency of encryption and decryption.

Description

technical field [0001] The present application relates to the technical field of network communication, in particular to a data transmission method, device and system. Background technique [0002] Nowadays, people pay more and more attention to the security of data, especially the security of data during transmission. Taking offline payment as an example, the server device can send a policy for generating a payment code to the client device, and the client device stores the policy. When the user needs to use the payment code, the client device can use the policy to generate the payment code. The merchant scans the payment code through the scanning device, and the scanning device transmits the scanned information to the server device for verification. After the verification is passed, the payment is deducted. It can be seen that in the process of transmitting policies from the server device to the client device, it is necessary to ensure the security of the channel between ...
