Research On Anonymous Authentication Scheme Of Internet Of Vehicles

With the rapid development of Internet of Things(Io T)technology,the self-organizing network of vehicles(also known as Internet of Vehicles)in intelligent transportation has attracted widespread attention due to its own uniqueness and beautiful development prospects.The way in which information is exchanged greatly improves the safety of traffic on the road.Vehicular Ad-hoc Network(VANETs)can connect the vehicle to the Internet or other vehicles in real time,and obtain various information required by the vehicle from the network in a wireless network.However,because the data transmission and management of the Internet of Vehicles rely heavily on wireless channels,the openness of the vehicle’s self-organizing network determines that the Internet of Vehicles will be vulnerable to potential threats such as information leakage and data attacks.It is necessary to further solve the problem of building a safe and reliable system that does not compromise the privacy of VANETs.This article does the following research on anonymous authentication related to Internet of Vehicles:(1)In order to protect the privacy of vehicles,some designers of Internet of Vehicles technology adopt anonymous authentication schemes.However,in these anonymity schemes,an abuse of anonymity is inevitable.In order to protect the privacy of vehicle users and prevent anonymous abuse,many conditional anonymous authentication schemes based on the principles of cryptography have been used in the use of Internet of Vehicles.However,most of these methods have complicated calculations and large communication overhead,which makes it difficult to meet the actual situation of VANETs network under the premise of high-speed driving.In order to solve this problem,this paper proposes a novel conditional anonymity scheme VKPCA(VANETs Kernel Principal component analysis).In the VKPCA scheme,the improved KPCA technology is used to reduce the dimensionality and encryption of vehicle feature information to achieve lightweight information.Interactive,the program can protect vehicle privacy and avoid anonymous abuse.Through simulation experiments,the results show that,compared with the traditional anonymous authentication scheme,the proposed VKPCA scheme has certain advantages in terms of computational complexity and communication overhead.(2)Different from the VKPCA scheme,in order to improve the requirements of the roadside unit(RSU)storage and computing capabilities in the VKPCA scheme,to ensure the safety of user information and improve the real-time nature of the information exchange of the vehicle linkage,this paper proposes a novel edge-based vehicle networking Calculated anonymous authentication scheme.In this scheme,the concept of edge computing is introduced into the Internet of Vehicles,and edge vehicle nodes are determined by a simple algorithm that defines distance and resources,and then the traditional RSA encryption algorithm is improved to encrypt user identity information,thereby ensuring the Internet of Vehicles users’ information security.This solution can reduce the burden of the roadside unit(RSU),effectively use the idle resources of edge vehicles to form an edge computing vehicle group,and improve the efficiency of vehicle authentication for the entire system while ensuring computing performance.It can not only protect the privacy of the vehicle,but also avoid anonymous abuse.Through experimental simulation,compared with the traditional anonymous authentication scheme,the scheme proposed in this paper not only ensures the security of user information,but also reduces the system’s computational and communication costs to a certain extent,and reduces the burden of RSU.
