| With the rapid development of automotive electronics,information technology and networks,the traditional information security problems that have arisen in the Internet and other fields have gradually threatened cyber-cars due to the openness of the Internet.it seriously hinders the direction of traditional networks to intelligent networks.A secure key management system is crucial for identification of vehicle,communication of vehicle,and the preservation of sensitive data in vehicles.The need for a key management system in the car-linked network has arisen.After studying the traditional key management system and software and hardware environment of the internet of vehicle,this thesis proposes a key management system suitable for the internet of vehicle.Compared with the traditional key management system,this system has added the terminal key management module and multitasking mechanisms.This system provides basic key management services for the entire vehicle network.The work of the thesis mainly includes the following points:(1)Implement a key management system which based on the AUTOSAR software architecture,the GP card specification and the PKI public key infrastructure specification.This system integrates the vehicle and ECU modules in the internet of vehicle with back-end application servers and crypto engines together,it provides key management functions to the car terminal application.(2)Analyze the application of white-box cryptography in the internet of vehicle,analyze the improvement of white-box cryptography for security of the key,and present the implementation of white-box for several asymmetric cryptographic algorithms.Also present the actual use scenario and method of the white box in the internet of vehicle. |
