Vehicle in vehicular ad hoc networks (VANETs) broadcasts beacons about their traffic status wirelessly for improving traffic safety and efficiency. Before deployment of the VANET system, problems related to security and privacy should be carefully addressed. In this paper, we propose a lightweight authentication with conditional privacy-preserving scheme for guaranteeing secure communication in VANET. The proposed scheme is suitable for addressing issues related to security and privacy because it combines the tamper-proof device (TPD) based schemes with the roadside unit (RSU) based schemes. Based on elliptic curve cryptography, the proposed scheme preloads the initial public parameters and keys of the system in each TPD of RSU instead of the TPD of the on-border unit (OBU). Furthermore, the proposed scheme not only achieve security and privacy requirements but also resists common security attacks. The performance evaluation shows that the proposed scheme has a lower cost compared with other existing schemes in terms of computation cost and communication cost. INDEX TERMS Authentication, tamper proof device (TPD), privacy-preserving, vehicular ad-hoc networks (VANETs). I. INTRODUCTION Recently, the intelligent transportation system (ITS) has attracted more deliberate attention from the motor industry, academia, and even government in recent years since it is reducing traffic congestion, enhancing driving efficiency, improving traffic safety, minimizing environmental pollution and providing convenience [1], [2]. Vehicular ad hoc networks (VANETs) are an entity of ITS with a fully a selforganizing wireless ad hoc communication system containing vehicles equipped with onboard unit (OBU), a trusted authority (TA) which preloads the initial public parameters of the VANET, and a road side unit (RSU) deployed at intersections in country, as presented in Figure 1. The communications types in VANETs contain two main modes: vehicle-tovehicle (V2V) communication and vehicle-to-infrastructure (V2I) communication [3], [4]. Dedicated short-range communication (DSRC) protocol is an open wireless technology which allows the vehicle for FIGURE 1: A typical VANET scenario. processing, receiving, broadcasting and communicating with each other or nearby RSU and exchanging messages such as

“…In the following, we briefly analyze current authentication protocols for WBANs and IoT. Some proposed authentication protocols are based on PKI, including [12], [13], [31]. PKI systems require a certificate authority (CA) to generate a certificate that binds the user's identity with his/her public key.…”

Lightweight Authentication Protocol Using Self-Certified Public Keys for Wireless Body Area Networks in Health-Care Applications

Health-care centers have been meeting challenges due to the increase in the aging population and chronic diseases that need continuous medical monitoring. Wireless body area network (WBAN) is a non-invasive technology consisting of diverse connected bio-medical sensors placed in the human body, which measure physiological parameters and make the information accessible to health-care professionals ubiquitously. However, a major problem in WBAN is the security and privacy of the patient's medical information. An essential security method to protect the physiological data is authentication. Several authentication protocols have been proposed for WBANs; however, some require many computing resources, and some have security vulnerabilities. In this article, the Two-Party Lightweight Authentication Protocol (TLAP) for WBANs is proposed. It uses self-certified public keys based on Elliptic Curve Cryptography (ECC), scalar point multiplication, symmetric key encryption, and the lightweight operations xor and conventional hash function to reduce the computational cost of the protocol. Formal and informal analyses were made to demonstrate that TLAP provides mutual authentication and resists potential attacks in WBANs. The security and performance of TLAP and similar existing protocols were analyzed and compared. The analyzes showed TLAP supports more security features and has lower execution time and communication cost than the other protocols, which is significant to decrease the energy consumption in WBANs.

“…Many PKI-based [7], [8], [9], [10], [11], [12] schemes have been proposed. The major shortfall of these approaches is that a large number of anonymous certificates and their respective public-private keys are placed in the OBU of the vehicle, which causes a massive certificate management burden for the TA.…”

LSWBVM: A Lightweight Security Without Using Batch Verification Method Scheme for a Vehicle Ad Hoc Network

et al. 2020

Recently, Vehicle Ad Hoc Networks (VANETs) have been increasingly developed in Intelligent Transportation Systems (ITSs). However, VANETs are vulnerable to security issues because of the open-medium nature of Vehicle-To-Vehicle (V2V) and Vehicle-To-Infrastructure (V2I) communication. Recently, many studies have proposed security schemes to address these issues. However, many of these schemes have massive computational overheads, especially in the process of batch verification method, which verifies multiple messages simultaneously. In this paper, a Lightweight Security Without Using Batch Verification Method (LSWBVM) scheme is proposed based on Elliptic Curve Cryptography (ECC). The proposed LSWBVM scheme uses the XOR operation and general hash function during mutual authentication. Meanwhile, to verify a large number of messages, the proposed scheme uses an efficient single verification instead of batch verification in a high traffic density-area. BAN logic proves that the LSWBVM achieves the security goals to mutually authenticate between the nodes. The security analysis indicates that the LSWBVM satisfies the security requirements, such as: identity privacy preserving, tractability and revocability; and secure non-forgery under the random oracle model in an adaptively chosen message attack. The preference evaluation shows that the single verification of proposed LSWBVM is more efficient when compared with batch verification of the related works. INDEX TERMS vehicular ad-hoc network (VANET); batch verification; authentication; random oracle model; BAN logic.
