“…The scheme does not need to rely on TPD and has a significant improvement in security features. In [28], Mamun and Miyaji proposed a scheme based on bilinear pairings.This scheme improves batch authentication of identification-based Group Signature (IBGS). The scheme improves the original scheme by batch scheduling algorithm, which improves the performance of authentication.…”

“…The experiments run on an Intel i7-9750 3 GHZ machine. According to [28], The following parameters are obtained: T mul is 0.39 ms, T mtp is 0.09 ms and T par is 4.5 ms. TABLE 3 shows a comparison of three schemes for the computational overhead of an RSU signed for a single message and n messages. The time required for the ECDSA scheme to validate a message is 4T mul , and the time required for the validation of n messages is 4nT mul .…”

As a part of intelligent transportation, vehicle ad hoc networks (VANETs) have attracted the attention of industry and academia and have brought great convenience to drivers. As an open communication environment, any user can broadcast messages in the system. However, some of these users are malicious users and malicious users can broadcast false messages to interfere with the normal operation of the system. Therefore, we needed to authenticate the identity of the message sender. Currently, there are two main authentication methods in VANETs, one using public key infrastructure (PKI) to verify message integrity and sender identity, and the other using anonymous authentication schemes. Due to the high computational and transport overhead involved in validation, the certification efficiency of most existing schemes is not satisfactory. Therefore, these schemes are generally not applicable to real-world scenarios. In order to improve the efficiency of certification and satisfy the security requirements, in this paper, we proposed a hybrid proxy based authentication scheme (HPBS). In HPBS, by introducing the concept of agent vehicles and integrating identity-based and PKI-based hybrid authentication, we solved three problems in the VANETs environment: (1) improving the effectiveness of roadside units (RSUs) in terms of authenticating messages; (2) reducing the computational burden of RSUs; (3) protecting the privacy of users. The simulation results illustrate that the scheme not only ensures network security, but also greatly improves the efficiency of information verification.

“…OBUs together with RSUs help to broadcast messages to other vehicles or transport system terminals in their range. Like RSU, the computing device in OBU is used to verify signatures or other computations in response to the messages received from other communicating vehicles . Nonetheless, traditional VANET possesses two kinds of communication policy, namely vehicle to vehicle, and vehicle to RSU .…”

“…The pseudonymity approach focuses on how often a node should change a pseudonym and with whom it should communicate. Besides that, some other schemes adopt group‐signature‐based solution (e.g., ) and traceable ring‐signature‐based solution (e.g., ) for VANET security and privacy. Group signatures can be directly used to anonymously authenticate vehicular communications without additionally generating a pseudonym.…”

Vehicle ad hoc network (VANET) provides communication between vehicles and vehicle-to-infrastructure communication. High mobility, high speed of vehicles, fast topology changes, and sheer scale are some characteristics that establish VANET as an intensive research topic different from other types of mobile ad hoc network. In this paper, we improve an existing batch verification system on ID-based group signature and also compare the performance achieved. Then, we analyze the best possible value of the number of signatures to batch at a time for large-scale VANET. In addition, we introduce a scheduling algorithm for signature verification where batch verification cannot be implemented efficiently.
