Vehicle-mounted safety communication method, system and device based on safety cloud public key protection

Abstract

The invention provides a vehicle-mounted security communication method, system and device based on security cloud public key protection. The intelligent networked automobile vehicle-mounted network communication comprises communication between a security cloud and a security TCU, communication between the security TCU and a security gateway, and communication between the security gateway and a security ECU, wherein the TCU is Telematics Control Unit; the security cloud and the security TCU communicate through a security wireless network communication technology, and bidirectional identity authenticity authentication is carried out between the security cloud and the TCU; and the security TCU and the security gateway are communicated by adopting a vehicle-mounted Ethernet security communication technology. The vehicle-mounted safety communication method, system and device based on the safety cloud public key protection have the beneficial effects that a whole set of safe, efficient and enforceable solution for network connection vehicle-mounted safety communication is provided, and the method comprises a public key data management and updating method based on the cloud safety protection; the invention discloses a challenge-response identity authentication method based on a public key cryptography technology, and a message encryption method based on a one-time session key.

Description

technical field [0001] The invention belongs to the field of intelligent networked automobile network security, and in particular relates to a method, system and device for vehicle safety communication based on safety cloud public key protection. Background technique [0002] With the rapid development of intelligent networked vehicles, vehicle network communication is facing more and more information security threats. Vehicle network communication lacks safe and efficient information security solutions. There are currently some solutions, most of which only solve the problem of vehicle communication message integrity. security problems, and most of them are based on the security schemes based on Ethernet networks, lack of research on the security schemes of the general vehicle communication network; and the existing schemes for identity authentication are only based on the public key pairs stored in the vehicle as The basis of identity verification is easy to be tampered wi...
