Method for achieving communication safety of vehicle-mounted electronic information system

Abstract

The invention discloses a method for achieving communication safety of a vehicle-mounted electronic information system. The method includes the steps that when vehicle-mounted information is output, a corresponding authentication and / or encryption algorithm is searched for in a security strategy library, and a data package is output after being authenticated and / or encrypted and packaged; when external data packages are input into the vehicle-mounted information system, the authentication and / or encryption algorithm used by the data package is searched for in a rule library according to a parameter index, and de-encapsulation is carried out on the data package by means of a found result to obtain a verification value or plaintext data package; the plaintext data package is searched for again in the security strategy library, if a specific security rule in the security strategy library corresponds to that obtained according to the parameter index of the data package, it means that the data package has no fake or deceptive behaviors and the data package passes verification, and the data package after de-encapsulation is input to an upper layer protocol and continues to be decrypted. By means of the method, safe, reliable and confidential communication of the vehicle-mounted information system can be guaranteed.

Description

technical field [0001] The invention relates to the field of vehicle-mounted electronic information security, in particular to a method for protecting data security during information exchange between a vehicle-mounted electronic information system and external equipment. Background technique [0002] In the era of connected cars in the future, cars have become a kind of "network terminal". In the process of more and more in-vehicle information being shared, they are faced with being hacked by cyber hackers and organized crime groups in a wider range through the in-vehicle network information system. The danger of attacking, and the power control in the vehicle information network is the guarantee of the safe driving of the car. Once it is broken, the personal safety of the driver will not be guaranteed. Due to the characteristics of embedded systems and previous vehicle networks, the security of vehicle network information has not attracted enough attention. As the types of...
