Design And Implementation Of Vehicle Time-Sharing Leasing System Based On Secure Interconnection

With the rapid development of mobile Internet and V2 X technology,networking has become the development trend of the automotive industry,and vehicle will be the next important mobile Internet entrance.And due to the popularity of shared economy,the vehicle time-sharing leasing service is rapidly rising and developing.The vehicle time-sharing leasing service is the combination of IoV and mobile Internet in the vehicle.It implements the transformation of vehicles from the tool to the service,and finally provides a new driving experience for the user.Currently,many domestic and foreign companies have also put forward the corresponding vehicle time-sharing leasing services.Such as GreenDogs vehicle rental,Car2 go,Evcard,Car2 Share and so on.However,according to research,development of China's vehicle intelligent networking service is not optimistic,most of the vehicle intelligent network service security is obviously inadequate,and there is a general lack of the protection of network information and related authentication function.In order to solve these problems,a vehicle time-sharing leasing system based on secure interconnection is proposed in this paper.It aims to provide the convenient communication between the vehicle,the mobile devices and the cloud service,and to strengthen the security of system,and to provide the secure and reliable vehicle time-sharing leasing service,The main work contains the following points:1)Studies the current terminal,cloud and vehicle architecture and analyzes its general problem of data transmission security and insufficient authentication function.2)Proposes a secure interconnection scheme based on the terminal,cloud and vehicle architecture,and design the overall architecture and divide common modules.Provides the corresponding short-range and remote network communication capabilities between people and vehicle.3)Design secure communication between roles in the secure interconnection scheme.Apply U2 F to achieve identity authentication between the mobile devices and the cloud service.Apply white-box cipher and HMAC to achieve the encrypted communication and identity authentication between the vehicle and the cloud service.And apply BLE to achieve the short-range encrypted communication and authentication between the mobile devices and the vehicle.4)Combined with the actual situation,achieve a vehicle time-sharing leasing system based on secure interconnection to implements and validates the design in this paper.
