“…Recently, many privacy-preserving authentication approaches have been proposed. These approaches can be broadly classified into group-based approaches [6] and pseudonymous-based approaches [7] and [8]. Alongside, there are Mix-zones, RSU-assisted [7], and a silent period [9].…”

The growth of the Internet has led to the increasing usage of smart infotainment applications on the vehicular ad-hoc network (VANET). Preserving privacy and security regarding the provision of smart infotainment applications while on the go is most desired. Thus, a secure authentication scheme is required. Many privacy-preserving security schemes have been developed in recent times using cryptography approaches. However, these incur key management and communication overhead. The usage of third-party servers incurs the overhead of key computation, storage and distribution. Post completion of the initialization phase, the message is secured using cryptography and is shared among vehicles. The design of the proposed secure enhanced non-cooperative cognitive division multiple access ( S − ENCCMA ) aims to eliminate the need for the local message available with the parties to be released for provisioning secure safety-related applications. To overcome the research challenges, this work presents a novel security scheme, namely secure non-cooperative cognitive medium access ( S − ENCCMA ). The experiment is conducted to evaluate the overhead incurred in provisioning security to ENCCMA . The outcome shows that the overhead incurred by S − ENCCMA over ENCCMA was negligible to provide the real-time security requirements of smart infotainment applications, which is experimentally shown in this paper in terms of throughput, collision and successful packet transmission considering varied environmental models such as cities, highways and rural areas.

“…Researchers have been devoted to resolve traffic problems and proposed various models. Existing techniques are based on group signature [7], pseudonymous [8], mix zones radio off [9], Efficient Conditional Privacy Preservation (ECPP) [10], AMOEBA [11], Communications Architecture for Reliable Adaptive Vehicular Ad Hoc Networks (CARAVAN) [12,13], and so on. These methods are an effort to resolve many issues associated with location privacy in VANETs, but every method has its own limitation.…”

.Vehicular ad hoc networks (VANETs) are the preferable choice for Intelligent Transportation Systems (ITS) because of its prevailing significance in both safety and nonsafety applications. Information dissemination in a multihop fashion along with privacy preservation of source node is a serious but challenging issue. We have used the idea of the phantom node as the next forwarder for data dissemination. The phantom node (vehicle) hides the identity of actual source node thus preserving the location privacy. The selection of the phantom node among the set of alternatives' candidate vehicles is considered as a multicriteria-based problem. The phantom node selection problem is solved by using an analytical network process (ANP) by considering different traffic scenarios. The selection is based on different parameters which are distance, speed, trust, acceleration, and direction. The best alternative (target phantom vehicle) is selected through an ANP where all the alternatives are ranked from best to worst. The vehicle having maximum weight is considered to be the best choice as a phantom node. In order to check the stability of the alternatives' ranking, sensitivity analysis is performed by taking into account different traffic scenarios and interest level of candidate vehicles.

“…However, due to the limited bandwidth of wireless communication and the high-speed mobility of vehicles, it is difficult to distribute a large CRL to all vehicles in a timely fashion. To decrease the CRL size, Bellur [11] suggests to segment a country into a number of geographic regions, and assign region-specific certificates with validity period to a vehicle. Lu et al [10] develop the efficient conditional privacy preservation protocol which is the first one to support legitimate vehicles updating short-time pseudonymous certificates from the RSUs frequently.…”

Group signature is one of the well-known cryptographic primitives for anonymous authentication which is the fundamental requirement for securing vehicular ad hoc networks (VANETs), but it is prone to cause huge revocation overhead in VANETs with millions of nodes and serious security risk. To solve this problem, we develop an efficient distributed key management scheme (DKM) where the whole domain of VANET is divided into several sub-regions, and any vehicle has to update its group secret key periodically from the regional group manager who manages the region where the vehicle stays. Unlike the previously reported works, DKM prevents vehicles from leaking the value of the updated group secret key to the regional group manager during the group key updating process. Subsequently, it is capable of identifying either the compromised regional authorities or the malicious vehicles. Moreover, performance analysis demonstrates that DKM can reduce the revocation cost significantly while the communication cost for key updating is small.In this part, we compare Hao's scheme with DKM in terms of communication cost for key updating, which is an important performance metric in wireless network. We consider the implementation of Tate pairing on an MNT curve [22] with embedding degree 6, where G is represented by 161 bits, and the order q is represented by 160 bits. The communication efficient short signature approach [20], is supposed to be used in Hao's scheme. Table IV show the communication results of Hao's scheme and DKM. Obviously, DKM performs better than Hao's scheme on both of communication turns and communication exchanged information. CONCLUSIONThe proposed DKM provides distributed key management for group-signature based authentication in VANET, which can decrease the revocation checking cost significantly. Security Comm.
