Abstract

The invention provides a key generation method of a vehicle application program. According to the key generation method of the vehicle application program provided by the embodiment of the invention, after the vehicle is sold, the safety factor corresponding to the region is generated according to the region where the vehicle is sold, then the preset key generation algorithm is called from the basic algorithm; based on the key configuration file and the safety factor, automatically generating a key of the vehicle application program through a key generation algorithm. According to the technical scheme, the generated key is not exposed to developers, the key is generated in an ECU (Electronic Control Unit), when the vehicle application program starts the key, the key does not need to be transmitted through a bus, and the concealment and the safety of the key are improved.

Description

technical field [0001] The present application relates to the field of vehicle network security, in particular to a key generation method and system for vehicle application programs. Background technique [0002] With the rapid development of vehicle intelligence, the risk of external threats to vehicle electronic control units is increasing. In order to ensure the security of the transmission and storage of vehicle bus data and other sensitive information, keys need to be introduced to improve the safe operation of vehicle security business applications. [0003] Currently, the keys used in vehicle applications are distributed and applied in a variety of ways without unified management. Under certain circumstances, the keys will be exposed to key operators or the communication process of the vehicle bus, and the concealment is poor. Contents of the invention [0004] In view of this, an embodiment of the present invention provides a key generation method, device, electro...
