Research On Securing Intelligent Platoon Management And Authentication For Vehicle

With the vehicle mobile terminal applications enriching and increasing, we demandhigher security of the vehicle networks. At present, the main type of vehiclecommunications are depend on the base stations and the roadside facilities. Informationexchange is not easily secured in emergency cases where normal telecommunicationsinfrastructure might have been collapsed. When vehicles are moving on a highway,communications between vehicles and base stations always result in high delay thatcauses a vehicle fails to verify all the messages received from its neighbors in real time.These situations may cause message losses and even security risks. To address theseissues, we propose a scheme that combines the technologies of Trusted NetworkConnect (TNC) and multi-secret sharing to Securing Authentication and Verificationfor Ad-hoc Vehicles (SAV4AV), in which a new vehicle is permitted to flexibly join ina platoon through collaborating with existing vehicles and thereby to accomplishidentity authentication and integrity verification. SAV4AV takes advantage of TPMhardware and the inherent encryption components to provide essential security services.Solving integrity verification problem with a (t, n) threshold-shared process. We listseveral possible attacks and provide a detailed security analysis on how to avoid thesethreatens in SAV4AV. Moreover, we perform extensive simulations to investigate theperformance of SAV4AV against various network scenarios.Many agencies are keep researching on platoon. Platoon itself is significant forenergy-saving emission reduction and driving safety. Due to development of automaticdriving derived and anti-collision applications, research gradually extended to the fieldof vehicle network. The vehicular communication system enables a dynamicconstruction of a platoon of the moving vehicles, resulting an increased trafficefficiency and safety. Meanwhile, this procedure could not leave the protection ofintegrate secure scheme. To deal with these issues, we propose a self-organized secureplatoon (SOSP) scheme. By extending Shamir’s threshold idea, we divide securityrequirements into different degree. During the distribution and recombination on SIQ, SOSP achieve to manage joining and canceling vehicles. To take advantage of secretdistribute and recombine procedures, SOSP could manage the vehicles in the platoonand avoid security risks effectively. Our scheme takes leader vehicle as the center whichmaintains a shared information queue (SIQ). In help of maintaining stability of platoon,authority management can choose most qualified successor. The other vehicles obtaininformation from SIQ and achieve a series of actions. Extensive simulations areconducted to verify the proposed scheme, which demonstrates that SOSP could solvemany problems including vehicles’ join and quit management, interaction managementand leader vehicles changing.
