“…We compare our proposed scheme with seven existing similar authentication schemes [9,[22][23][24][25][26][27], including a pairing-free authentication scheme [9] for VANETs and six key-insulated authentication schemes [22][23][24][25][26][27]. Note that in our comparison, only consumption of signing phase and verification phase is put into consideration.…”

“…Based on this defect, another secure authentication scheme was introduced by Bayat et al [8] to improve it. Wang and Yao [9] proposed the LIAP scheme, in which the vehicle and RSU are assigned with a long-term certification from the certificate authority (CA). If the vehicle is compromised, CA could easily revoke the vehicle's long-term certificate to terminate its behavior in the network.…”

“…To show the advantage clearly, the improved ratio of our scheme against other seven schemes is defined as (T [num] − T [ours] )/T [num] , where T [num] refers to time costs of the scheme with the reference number "num" and T [ours] refers to time costs of our scheme. In terms of the verification stage, the improved ratios of our scheme against the schemes [9,[22][23][24][25][26][27] Figures 3 and 4, the computation costs of singing phase of our proposed scheme are lightly higher than some schemes, because indispensable operations in this phase are needed to achieve key insulation and to provide better security. Even that our promotion comes at a little price of efficiency of signing, the gain of keyinsulated secrecy deserves it, and on the whole, the proposed scheme achieves a better trade-off between security and efficiency than the compared schemes.…”

“…In terms of the verification phase, according to Table 3, in the scheme of Wang and Yao [9], RSU needs to run two hash operations, three bilinear pairing operations, and one multiplication operation.

e advent of intelligent transportation system has a crucial impact on the traffic safety and efficiency. To cope with security issues such as spoofing attack and forgery attack, many authentication schemes for vehicular ad hoc networks (VANETs) have been developed, which are based on the hypothesis that secret keys are kept perfectly secure. However, key exposure is inevitable on account of the openness of VANET environment. To address this problem, key insulation is introduced in our proposed scheme. With a helper device, vehicles could periodically update their own secret keys. In this way, the forward and backward secrecy has been achieved. In addition, the elliptic curve operations have been integrated to improve the performance. e random oracle model is adopted to prove the security of the proposed scheme, and the experiment has been conducted to demonstrate the comparison between our scheme and the existing similar schemes.

With the development of the vehicular ad hoc network, the security and privacy are now becoming vital concerns, especially when the attacker owns more and more resources. In order to address these concerns, a dynamic anonymous identity authentication scheme is proposed using Elliptic Curve Discrete Logarithm Problem and blockchain method, which guarantees the security and fast off-line authentication for vehicle-to-infrastructure. Specifically, a dynamic pseudonym key is generated using tamper proof device (TPD) for off-line authentication and anonymity when a vehicle roams among different roadside units' (RSUs) communication ranges. Even if all RSUs are compromised, vehicle's identity is still privacy. Moreover, two additional design goals are more suitable for the practical environment: (1) the reduced assumption of TPD;(2) certification authority can trace vehicle under the authorization by law. KEYWORDSblockchain, dynamic anonymous authentication, ECDLP, VANET | INTRODUCTIONWith the development of the transportation industry, unmanned technology has received more and more attention from the academic and technical field; however, sometimes its safety is questioned. In particular, on 22 March 2018, a serious accident occurred that Uber's self-driving car crashing into a pedestrian in Tempe, Arizona. Especially, the most common accidents are due to that the in-vehicle sensors are not able to perfectly identify pedestrians, vehicles, and static obstacles and the low range of vehicle sensors cannot give the vehicle enough reaction time. For example, in May 2016, the Model S hits the truck that was turning in the auto-driving state. Because the truck body was reflective, the camera did not recognize the opposite truck. With the development of wireless technologies and the intelligent transportation systems, vehicular ad hoc network (VANET) is being gradually applied to the unmanned vehicle, the vehicle enters VANET as a single node to share data such as weather, traffic conditions, driving trajectory, etc. VANET shares the information for all vehicles, which can greatly reduce the traffic accidents caused by a sensor failure; therefore, VANET is a feasible solution to improve the road safety and reduce traffic accidents of the urban traffic.Vehicular ad hoc network mainly consists of certification authority (CA), roadside units (RSUs), and vehicles. CA is mainly responsible for the entire system. RSUs are placed on the roadside, broadcast the service information from CA to vehicles within the communication area, and accept the requesting messages or traffic condition from vehicles. Usually, the communication in VANET can be divided into two types: vehicle-to-vehicle and vehicle-to-infrastructure (V2I), which are built according the basic standard, such as dedicated short range communication. Since these communications are over open channel, the security requirements play an important role. 1-3

Vehicular communication networks are traffic applications of the Internet of Things consisting of vehicle nodes, roadside units, service providers, and other components. To protect the vehicle privacy, some vehicular communication networks adopt anonymous schemes. However, in these anonymous schemes, anonymity abuse is inevitable. In order to protect vehicular privacy and prevent anonymity abuse, some conditional anonymous authentication schemes based on cryptography have been proposed. However, most of these methods have complex computation and large communication overhead, which makes them difficult to meet the actual requirement of high-speed traffic in vehicular communication networks. In this paper, a novel conditional anonymity scheme called VKPCA (vehicular communication network based on kernel principal component analysis [KPCA]) is proposed, which can protect vehicle privacy while avoid anonymity abuse. The simulation results show that this scheme has lower computational complexity and communication overhead than the conventional anonymous authentication scheme.
