Design And Implementation Of Intelligent Connected Vehicle Information Security Detection System

Vehicle terminal is the core link to ensure the overall information security of the vehicle,and it is also the most vulnerable part to external attacks.At the same time,the mandatory implementation of GB17691-2018 standard(CN6 standards)makes more and more vehicle terminals need to pass information security detection,but the penetration test scheme required in the standard is not clear.Therefore,it is necessary to develop a communication simulation system between vehicle terminal and telematics service provider(TSP)according to GB17691-2018 standard to lay a platform foundation for studying more effective penetration test schemes.Based on the above background,this thesis analyzes the security status of Internet of Vehicles,and analyzes in detail GB17691-2018 standard protocol for vehicle terminal transmission and the key technologies required for man-in-the-middle attack test.Then according to the requirements of the project book,the functional,extended functional and non-functional requirements of the project are analyzed.In order to realize the simulation of vehicle-TSP communication system,this thesis designs a vehicle-TSP communication simulation system based on GB17691-2018 standard according to the basic functions of real vehicle terminal and TSP management server.Firstly,the technical scheme of vehicle-TSP communication simulation system is studied,and the communication technology under the architecture of vehicle terminal and TSP management server is analyzed.The simulation platform of vehicle terminal and TSP management server is built.Then the overall design of the system,and completed the system architecture and modular design and detailed design and implementation of each functional module.In order to verify the effectiveness of the vehicle-TSP communication simulation system for the study of penetration testing,this thesis also designs a man-in-the-middle attack verification platform.The platform carries out effective data intrusion in the vehicle-TSP communication simulation system,and realizes the functions of the verification system such as hijacking and tampering of protocol data in transmission.In order to better carry out the research on the penetration test scheme on the built vehicle-TSP communication simulation system in the future,the classification and identification module of the unknown protocol is pre-researched,which lays the foundation for the reverse analysis of the protocol and the penetration test for the unknown protocol.Finally,according to the project design requirements,the test environment is built,and the vehicle-TSP communication simulation system is combined with the man-inthe-middle attack verification platform to complete the functional test,and the extended module of the pre-research is evaluated experimentally.The test results show that all the functional indexes of the vehicle-TSP communication simulation system meet the requirements of the project.The vehicle-TSP communication simulation system designed and implemented in this thesis can better study the penetration test scheme,and the pre-developed expansion module can also better meet the requirements of the penetration test in the later projects.
