Secure communication method based on intelligent vehicle

Abstract

The invention discloses a secure communication method based on an intelligent vehicle. The secure communication method comprises the steps: an intelligent vehicle client randomly generates a number which is used as the secret key for a communication symmetric encryption algorithm and verifies a server, and generates a symmetric secret key by using an asymmetric encryption algorithm and sends the symmetric secret key to the server; the server uses a private key to decrypt messages, and uses the symmetric encryption algorithm to encrypt a handshake text 'hello, zjuroboy !' and replies the encrypted handshake text 'hello, zjuroboy !' to the client; the client uses the symmetric encryption algorithm to decrypt the handshake text; the client uses the symmetric encryption algorithm to encrypt an intelligent vehicle serial number and MASK if verification is successfully; the server decrypts the verification information to obtain the serial number and the MASK so as to verify the identity of the intelligent vehicle; and based on the established connection, the intelligent vehicle and the server use the symmetric encryption algorithm to perform bidirectional communication. The secure communication method based on an intelligent vehicle can remove three hidden dangers that the communication content is eavesdropped; the communication identity is camouflaged; and the communication content is tampered during the communication process between the intelligent vehicle and the server.

Description

technical field [0001] The invention relates to a safe communication method for an intelligent vehicle. Background technique [0002] Communication between the smart car and the server in the form of plain text has great security risks. Specifically, there are three security risks as follows: the communication content is eavesdropped, the communication identity is disguised, and the communication content is tampered with. [0003] Since the above information is transmitted in the Internet, and the so-called Internet is composed of networks that can connect to the whole world, no matter where the server and client are in communication, the routers and switches on the entire communication line Network equipment such as bridges and bridges cannot all be the private property of a certain person, so there is no guarantee that these links will not be eavesdropped, and the identity will be disguised and tampered with. Once a message transmitted in plaintext is stolen, the stealin...

AI Technical Summary

Problems solved by technology

The server does not refuse any request to establish a connection, so there is a situation where someone pretends to be a smart car and sends false smart car information to the server, while the real smart car is at risk of being stolen

It is also possible that someone pretends to be the server and sends false control commands to the smart car, which poses a great security risk

Since the integrity of the message cannot be verified during the communication between the smart car and the server in the form of plain text, that is, whether it has been tampered with, there may be a security risk that the message is modified by a hacker in the middle
