“…VANETs offers many types of applications such as effective management applications [9][10][11] (route planning and urban traffic monitoring), cost-effective applications 12,13 (vehicle location-based services, shortest route planning, and so on), entertainment applications (audio and video sharing, Internet facility, social networking, and so on) and security applications [14][15][16][17] (rear vehicle warning, road status information, road ice testing, and so on). Moreover, the communications among vehicles in the wireless environment are simply targeted when they are sharing sensitive information with other vehicles in that group.…”

The advent of group‐oriented communication applications in Vehicular Ad Hoc Networks (VANETs) has trigger research on lightweight privacy‐preserving Secure Group Communication (SGC) in VANETs. In view of this, many researchers proposed privacy‐preserving, authentication, and key agreements schemes. However, these schemes need to address the dynamic nature, heavier processing loads, massive storage, and higher communication. In this direction, we proposed a framework for lightweight dynamic SGC with privacy‐preserving and authentication in VANETs, encompassing (i) A lightweight Elliptic Curve Cryptography (ECC)‐based two‐party key agreement and its extension to a Dynamic Group Key Agreement, in which fixed Road Side Unit (RSU) acts as Group Controller (GC) with superior computational ability than the On‐Board Unit equipped on the vehicles. (ii) An identify‐based authentication and privacy‐preserving schemes using only two lightweight operations XOR and hashing. (iii) A lightweight encryption and decryption with Exclusive Or (XOR) and hashing only. And (iv) a formal security model for SGC in VANETs. The security analysis shows that the proposed system provides confidentiality of session key, anonymity, secure session key enhancement, and immune to password guessing attack, replay attack, insider attack based on an assumption of the computational G‐ECDDH problem. The experimentation is done for authentication, group key agreement, encryption, and decryption times by a varying number of vehicles in the group to 10, 20, 40, 60, 80, and 100 and shown that the proposed technique is taking considerably less computation than other techniques. So the proposed technique is highly desirable in VANETs.

A vehicular ad hoc network (VANET) is a special mobile ad hoc network that provides vehicle collaborative security applications using intervehicle communication technology. The method enables vehicles to exchange information (e.g., emergency brake). In VANET, there are many vehicle platoon driving scenes, where vehicles with identical attributes (location, organization, etc.) are organized as a group. However, this organization causes the issue of security threats (message confidentiality, identity privacy, etc.) because of an unsafe wireless communication channel. To protect the security and privacy of group communication, it is necessary to design an effective group key agreement scheme. By negotiating a dynamic session secret key using a fixed roadside unit (RSU), which has stronger computational ability than the on-board unit (OBU) equipped on the vehicle, the designed scheme can help to provide more stable communication performance and speed up the encryption and decryption processes. To effectively implement the anonymous authentication mechanism and authentication efficiency, we use a batch authentication scheme and a shared secret key mechanism among the vehicles, RSUs and trusted authority (TA). We design an efficient group secret key agreement scheme, which satisfies the above communication and security requirements, protects the privacy of vehicles, and traces the real identity of the vehicle at a time when it is necessary. Computational analysis shows that the proposed scheme is secure and more efficient than existing schemes.

“…In order to increase the realism of the scenario under investigation, combining multiple simulation platforms is a route often taken. Mylonas [10] and Bhakthavathsalam [11] evaluated inter-vehicle communication protocols and applications through the integration of microscopic simulation programs (VISSIM, SUMO) and discrete event communication simulation engines (OPNET, NS-2). They demonstrated that the approach was valid when developing such applications however as they focused on inter-vehicle communication, they were not concerned by car-following models.…”

Abstract-While vehicle automation has the potential to significantly improve safety and traffic efficiency, the full potential will only be realised when vehicles start exploiting wireless communication to cooperate with each other and coordinate their interactions in advance. Ensuring that vehicles coordinate safely while improving efficiency is, however, a very challenging problem as it depends on (i) the characteristics of individual vehicles (vehicle physics, sensors), (ii) unreliable wireless communication, and (iii) driving behaviour at a microscopic level, and their compounded effects at scale. The presence of non-communicative, non-automated vehicles must also be considered.Designing and evaluating coordination protocols requires a scalable simulation framework that is accurate both microscopically (to assess safety) and macroscopically (to evaluate efficiency). Standard car-following models, where position and velocity are dictated by local input stimuli, produce sometimes unrealistic behaviour when laterally changing position, and lack support for additional inputs. Furthermore, conventional environments used to model traffic flow are either too fine-grained to scale or too coarse to appropriately simulate control logic. This paper introduces RoundaSim consisting of (i) a traffic simulator using a novel approach of mixed discrete-continuous modes of time, and (ii) a framework for implementing carfollowing models that supports lane-changing and coordination protocols, with additional inputs from advanced sensors and wireless communications. We show how our framework can be used to implement and evaluate a car-following model with lane changes and validate that the traffic flow achieved approximates that of real-world highways. This allows our platform to be used as a baseline for evaluating the safety and efficiency of coordination protocols.
