“…Communication among vehicles, and between an RSU and an OBU is referred to as vehicle‐to‐vehicle (V2V) and is achieved using a dedicated short‐range communication (DSRC) protocol; while the TA, RSUs, and an application server (AS) communicate using a secure wired channel such as the Internet . According to VANET requirements, by using the DSRC protocol, each OBU frequently broadcasts traffic‐related information every 100‐300 ms . RSUs can collect traffic‐related data from OBUs, verify their authenticity and integrity, and then transmit the valid data to the AS for analysis.…”

Certificateless aggregate signature (CLAS) scheme is a very important cryptographic technique used in many internet of things (IoT) applications like healthcare wireless sensor networks, industrial IoT, smart agriculture, and smart transportation to achieve privacy and integrity of transmitted information, and improved efficiency. Recently, a privacy-preserving authentication scheme based on CLAS scheme for secure communication in vehicular ad hoc network (VANET) which can achieve complete aggregation was proposed. The authors demonstrated that their scheme is semantically secure in the random oracle model based on the intractability of the computational Diffie-Hellman (CDH) problem under the consideration of type I and II attacks. However, by giving two concrete attacks, we show that the scheme is insecure in the standard security model. Consequently, we propose a fix by modifying the sign, verify, and aggregate-verify algorithms of the scheme. Afterwards, we demonstrate that with this modification, the improved scheme is semantically secure against forgery attacks in the random oracle model under the intractability of the CDH problem. An analysis of the performance of the proposed scheme and the related schemes shows the former is much more efficient and suitable for practical application.

In recent times, vehicles equipped with communication devices known as on-board units (OBUs) are emerging. Furthermore, roadside units (RSUs) are also being deployed along the roadside and at intersections to allow communication between vehicles and infrastructure. This new paradigm has innovated a self-organizing network known as vehicular ad hoc network (VANET). In general, as shown in Figure 1, a VANET consists of a trusted authority (TA), OBU-installed vehicles, and RSUs. Communication among vehicles, and between an RSU and an OBU is referred to as vehicle-to-vehicle (V2V) and is achieved using a dedicated short-range communication (DSRC) protocol 1 ; while the TA, RSUs, and an application server (AS) communicate using a secure wired channel such as the Internet. 2 According Security Privacy. 2020;3:e104. wileyonlinelibrary.com/journal/spy2

Summary Recently, Maria Azees et al proposed an “EAAP: efficient anonymous authentication with conditional privacy‐preserving scheme for Vehicular Ad Hoc Networks.” Their scheme is mainly to solve the problem of high computation time of anonymous certificate and signature authentication, as well as the tracking problem of malicious vehicles. However, some improvements are needed in the protection of anonymous identity and the effective tracking of malicious vehicles. In this paper, our scheme realizes mutual authentication between OBU and RSU, and the RSU is authenticated without using certificate. In order to prevent the anonymous identity of the vehicles from being monitored and tracked, we use the negotiated short‐time key to encrypt the anonymous identity in the vehicle certificates. In addition, our scheme uses a new tracking method for malicious vehicles. Then, we prove the scheme through BAN logic, and it has the properties of authentication, anonymity, unlinkability, privacy protection, and traceability. Finally, we compare the computation cost and communication cost with other schemes, and the scheme has been greatly improved.

Summary In the traffic monitoring system, the transportation department generates the traffic map to report the real‐time traffic conditions, so as to provide more efficient service for drivers. However, if the vehicle obtains the local traffic conditions that the driver is more concerned about from the remote server, it will consume a heavy bandwidth and incurs an increased response delay. Generating and broadcasting local traffic conditions through fog computation is a feasible method to reduce communication costs, and most existing traffic monitoring systems based on fog computation are implemented using Bilinear Pairing operations. In this paper, we propose Lightweight and Privacy‐preserving Traffic Monitoring (LPTM) scheme with Elliptic Curve Cryptosystem, an optimized Timed Efficient Stream Loss‐tolerant Authentication protocol is adopted to achieve efficient and secure communication, and we also use an identity‐based signature scheme with partial message recovery to effectively shorten the length of the fog node broadcast message. Detailed security proofs show that the requirements of security and privacy are all achieved, and better simulation performance is presented in both computation and communication overhead.
