Problems solved by technology

[0002] With the wide application of the network in daily life, the background server of the vehicle terminal often faces malicious attacks from hackers, causing the server to be paralyzed and unable to work normally.
For example, a hacker can capture the interaction data packets between the vehicle terminal and the server, and imitate the interaction data packets of the vehicle terminal, and maliciously send a large amount of high-load data to the server. Since the server does not identify whether the data is the interaction data sent by the vehicle terminal, Make the server high load to process interactive data, which can cause the server to be paralyzed
[0003] In order to prevent hackers from sending a large amount of data to the server by imitating the data of the vehicle terminal, the current solution is to encrypt and decrypt the vehicle terminal and the server through a preset password, so that the hacker cannot decode and imitate the interactive data
However, since both parties have the same password and only use the same password for encryption and decryption, the risk of password leakage is very high. When the password is leaked, hackers can still attack the server by imitating the interactive data of the vehicle terminal, causing the server to be paralyzed

Abstract

The embodiment of the invention discloses a data transmission method, comprising: when a vehicle terminal is required to send data to be sent to a server in connection with the vehicle terminal, the vehicle terminal generating a private key according to a preset rule; the vehicle terminal encrypting the data to be sent according to the private key to obtain a signature; and the vehicle terminal deleting the private key, and sending the signature and the data to be sent to the server in connection with the vehicle terminal. The embodiment of the invention also discloses a device and a system. According to the invention, the data transmission security of the vehicle terminal can be improved.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a data transmission method, device and system. Background technique [0002] With the wide application of the network in daily life, the background server of the vehicle terminal often faces malicious attacks from hackers, causing the server to be paralyzed and unable to work normally. For example, a hacker can capture the interaction data packets between the vehicle terminal and the server, and imitate the interaction data packets of the vehicle terminal, and maliciously send a large amount of high-load data to the server. Since the server does not identify whether the data is the interaction data sent by the vehicle terminal, The server is heavily loaded to process interactive data, which can cause the server to be paralyzed. [0003] In order to prevent hackers from sending a large amount of data to the server by imitating the data of the vehicle terminal, t...
