Encryption method and system for communication between mobile terminal and vehicle

Abstract

The invention discloses an encryption method and system for communication between a mobile terminal and a vehicle. The encryption method comprises the following steps that the mobile terminal initiates an identity recognition request; after the identity recognition is successful, the public network cloud platform processes an authentication code ciphertext generated by the whole vehicle computer and then sends the authentication code ciphertext to the mobile terminal, and the mobile terminal sends an analyzed vehicle authentication code to the whole vehicle computer through the public network cloud platform; after receiving the vehicle authentication code, the whole vehicle computer performs matching, after matching succeeds, the public network cloud platform issues a vehicle control request key rule, the mobile terminal encrypts a control request signal through a key and then sends the control request signal to the whole vehicle computer, the whole vehicle computer decrypts the control request signal through the key, after decryption succeeds, the public network cloud platform issues a vehicle control information key rule, and the vehicle control information key rule is sent to the whole vehicle computer. The mobile terminal encrypts the control instruction signal through the new secret key and then sends the control instruction signal to the whole vehicle computer, and the whole vehicle computer analyzes the control instruction signal through the new secret key and processes related operation. The problem of data information security of current vehicle communication is solved.

Description

technical field [0001] The invention relates to the field of vehicle communication, in particular to an encryption method and system for communication between a mobile terminal and a vehicle. Background technique [0002] Against the background of scientific and technological progress and huge market demand, automobiles are no longer simple means of transportation, but electronic vehicles integrating safety, environmental protection, comfort, entertainment, office and service. With the rapid development of modern electronic technology, computer technology and communication technology, remote communication and information systems have gradually entered the car, and car functions have begun to develop toward diversification and integration, which further increases the requirements for in-car information transmission and communication. . However, the current traditional network construction method of forming physical connections through wire harnesses can no longer meet the ne...
