Abstract

The invention relates to a data transmission method, a first terminal and a second terminal, and the method for the first terminal comprises the steps: generating a first timestamp and a second timestamp according to a data package when the data package is received; generating a message header according to the first timestamp and preset verification information; generating an encryption key according to the second timestamp; encrypting the data packet by using the encryption key to obtain a first ciphertext; attaching the message header to the first ciphertext to obtain a second ciphertext; and sending the second ciphertext to the second terminal, so that the second terminal verifies the integrity of the second ciphertext according to the message header. The scheme can improve the integrity of data transmission.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a data transmission method, a first terminal and a second terminal. Background technique [0002] At present, when two remote computers transmit data, the data sent by the sender needs to go through various network media to reach the receiver. During data transmission, the maximum length of data packets is limited because the link layer has the characteristic of maximum transmission unit. If the length of the data packet exceeds the transmission capacity of the maximum transmission unit, it is often necessary to divide the data packet into multiple sub-packets to ensure the transmission of the data packet on the link. [0003] However, due to the time loss in the transmission process, the order of each sub-packet may be disordered or even lost during the transmission process, resulting in poor integrity of data transmission. [0004] Therefore, in view of the ...
