Research And Implementation Of IBC-based Security Authentication And Privacy Protection Of Internet Of Vehicles

The Internet of Vehicles(Io V)is a special self-organizing network.Its core concept is to improve the efficiency of traffic and the safety of vehicles through the interconnection and information sharing of information between people,vehicles,roads and clouds.In the Internet of Vehicles,secure message transmission between nodes needs to rely on the mobile cellular network 4G/5G or wireless WIFI network.Due to the open network environment,the Internet of Vehicles system faces many network security threats.In the Internet of Vehicles,security certification is required to ensure communication between nodes and privacy security.The high mobility of nodes in the Internet of Vehicles makes the Internet of Vehicles network links have the characteristics of weak stability and rapid network topology changes,which puts forward high requirements for the real-time nature of messages between nodes.At this stage,the safety certification scheme has problems such as complex design,difficult management,and difficult implementation,and it is difficult to meet the requirements for safety certification in the Internet of Vehicles.Therefore,it is very necessary to design and implement an efficient car networking safety certification scheme.Based on the in-depth study of the Internet of Vehicles network model,this paper analyzes the security threats and security requirements of different communication scenarios and business models in the Internet of Vehicles,and designs and implements an efficient authentication based on Identitybased Encryption(IBC)The plan,the main work and innovations of this article are as follows:1.Private key distribution in the IBC system generally adopts the offline distribution method of key fobs,which is difficult to meet the online needs of the Internet of Vehicles.This paper studies a combination of Public Key Infrastructure(PKI)and IBC for authentication.Nodes and Key Generator Center(KGC)in the Internet of Vehicles use certificates for security authentication,and IBC between nodes verification method.The node uses the certificate to apply for the private key from KGC,realizing the real-time and online private key application requirements.2.Aiming at the privacy and security issues of nodes in the Internet of Vehicles,this paper proposes a pseudonymous authentication mechanism based on IBC.KGC generates and distributes pseudonymous identification IDs for vehicles.Vehicles use pseudonymous identifications instead of real vehicle IDs for secure communication activities and regularly replace pseudonyms.The identification ID realizes the privacy and security of the vehicle in the Internet of Vehicles.When necessary,the KGC can be traced back to the true identity of the vehicle.This scheme KGC uses calculation to trace the true identity of the vehicle,which has high traceability and saves management costs.3.This paper designs the CA system and KGC system based on the B/S architecture.The CA system distributes the national secret SM2 certificate,and the KGC system is implemented based on the Gm SSL Chinese-made SM9 identification password.Finally,multiple PC virtual machines are used to simulate the on-board Linux system to realize the security authentication process between nodes with the help of socket communication.Experiments show that this scheme is an efficient security authentication scheme and has a huge advantage in the traceability of the true identity of the vehicle.
