Security Methods in Internet of vehicles

The emerging wireless communication technology known as vehicle ad hoc networks (VANETs) has the potential to both lower the risk of auto accidents caused by drivers and offer a wide range of entertainment amenities. The messages broadcast by a vehicle may be impacted by security threats due to the open-access nature of VANETs. Because of this, VANET is susceptible to security and privacy problems. In order to go beyond the obstacle, we investigate and review some existing researches to secure communication in VANET. Additionally, we provide overview, components in VANET in details

Conditional privacy-preserving authentication using registration list in vehicular ad hoc networks.

Vehicular ad hoc networks (VANETs) have increased in popularity in recent years and play an extremely important role in the intelligent transportation field. However, the demands of larger communication networks and the integrated message verification process for ensuring security incur more communication and computation overheads, and directly affect the efficiency of existing VANET schemes. To address this issue, this paper proposes a novel and practical conditional privacy-preserving authentication (CPPA) scheme, which uses the registration list instead of the revocation list to reduce the communication overhead. Specifically, our scheme can prevent malicious vehicles from disrupting the security features of VANETs. Moreover, we do not use the bilinear pairing operation, which is the most complicated operation in modern cryptography, thus significantly reducing the computation overhead and communication overhead. Security and performance analyses demonstrate that our proposed scheme is more secure and efficient than current schemes, and that the proposed scheme is more suitable for VANET deployments.N/

Review of Prevention Schemes for Modification Attack in Vehicular Ad hoc Networks

Vehicular Ad-hoc Network (VANET) technology is the basis of Intelligent Transportation System (ITS) connectivity that enables the delivery of useful information to and fro between vehicles in vehicle-to-vehicle communication mode; or between vehicle and infrastructure in vehicle-to-infrastructure mode for safety and comfort. However, due to the openness of the wireless medium used by VANET, the technology is vulnerable to security threats in both communication modes. In this study, the essential background of VANET from architectural point of view and communication types are discussed. Then, the overview of modification attack in VANET is presented. In addition, this paper thoroughly reviews the existing prevention schemes for modification attack in VANET. This review paper reveals that there is still a need for a better and more efficient preventive scheme to address the modification attack in VANET

Secure Location-Aided Routing Protocols With Wi-Fi Direct For Vehicular Ad Hoc Networks

Secure routing protocols are proposed for the vehicular ad hoc networks. The protocolsintegrate the security authentication process with the Location-Aided Routing (LAR) protocol to supportWi-Fi Direct communications between the vehicles. The methods are robust against various security threats.The security authentication process adopts a modified Diffie-Hellman key agreement protocol. The Diffie-Hellman protocol is used with a short authentication string (SAS)-based key agreement over Wi-Fi Directout-of-band communication channels. It protects the communication from any man-in-the-middle securitythreats. In particular, the security process is integrated into two LAR routing schemes, i.e., the request-zoneLAR scheme and the distance-based LAR scheme.We conduct extensive simulations with different networkparameters such as the vehicular node density, the number of the malicious nodes, and the speed of thenodes. Simulation results show that the proposed routing protocols provide superior performance in securedata delivery and average total packet delay. Also, the secure distance-based LAR protocol outperforms thesecure request-zone LAR protocol

A Conditional Privacy Preserving Authentication and Multi Party Group Key Establishment Scheme for Real-Time Application in VANETs

Vehicular Ad-hoc Networks (VANETs) are a cardinal part of intelligent transportation system (ITS) which render various services in terms of traffic and transport management. The VANET is used to manage growing traffic and manage data about traffic conditions, weather, road conditions, speed of the vehicle, etc. Even though, VANETs are self-sufficient and effective networks but they still suffer from various security and privacy issues. VANETs need to ensure that an adversary should not be able to breach user associated data and delete or modify the exchanged messages for its gains, as these messages comprise of sensitive data. In this paper, we have proposed an authentication and key-agreement protocol based on cryptographic hash functions which makes it lightweight in nature and also suitable for VANET environment. Moreover, to enhance the security and reliability of the entire system, the proposed key-agreement protocol makes use of random session modulus to compute a dynamic session key i.e. for every session, vehicles generate their session specific secret modulus which are then converged to form a common group session key. The formal verification of the proposed work is done using Real - or - Random oracle model, AVISPA and BAN Logic while informal security analysis shows that the proposed protocol can withstand various attacks. The simulation results and analysis prove that the proposed work is efficient and has a real-time application in VANET environment

Security Analysis of Efficient Anonymous Authentication With Conditional Privacy Preserving Scheme for Vehicular Ad Hoc Networks

Protecting a driver’s privacy is one of the major concerns in vehicular ad hoc networks (VANETs). Currently, Azees et al. has proposed an efficient anonymous authentication protocol (EAAP) for VANETs. The authors claim that their scheme can implement conditional privacy, and that it can provide resistance against impersonation attack and bogus message attack from an external attacker. In this paper, we show that their scheme fails to resist these two types of attack as well as forgery attack. By these attacks, an attacker can broadcast any messages successfully. Further, the attacker cannot be traced by a trusted authority, which means their scheme does not satisfy the requirement of conditional privacy. The results of this article clearly show that the scheme of Azees et al. is insecure

Review of Prevention Schemes for Man-In-The-Middle (MITM) Attack in Vehicular Ad hoc Networks

Vehicular Ad-Hoc Network (VANET) is an indispensable part of the Intelligent Transportation System (ITS) due to its abilities to enhance traffic management and safety. Many researchers have been focused on specific areas involving management and storage data, protocols standardization, network fragmentation, monitoring, and quality of service.  The benchmarks of security of VANET are studied and figured out in this paper. VANET provides the driver and passenger with the safety application as well as entertainment service. However, the communication between nodes in VANET is susceptible to security threats in both communication modes, which indicates the main hazard. In this paper, we identified different Man-In-The-Middle (MITM) attacks with various behaviors such as message tampering, message delaying, and message dropping, according to the literature. In this study, the essential background of VANET from architectural point of view and communication types are discussed. Then, the overview of MITM attack in VANET is presented. In addition, this paper thoroughly reviews the existing prevention schemes for MITM attack in VANET. This review paper reveals that there is still a need for a better and more efficient preventive scheme to address the MITM attack in VANET. This review paper could serve as evidence and reference in the development of any new security schemes for VANETs

A cost-effective identity-based signature scheme for vehicular ad hoc network using hyperelliptic curve cryptography

A Vehicular Ad Hoc Network (VANET) is a subset of the Mobile Ad Hoc Network (MANET) that allows vehicles to communicate with each other and with roadside stations to offer efficient and safe transportation. Furthermore, when VANET is used in connection with the Internet of Things (IoT) devices and sensors, it can help with traffic management and road safety by allowing vehicles to interact with one another at any time and from any location. Since VANET's event-driven communications are carried out via an open wireless channel, there are significant security concerns. In this paper, we use Hyperelliptic Curve Cryptography (HECC) to offer a cost-effective identity-based signature for secure communication over VANET. The proposed scheme does not need certificate management, and we found that it is more secure against a variety of cryptographic threats after conducting a thorough security analysis. In addition, comparisons of communication and computational costs are made, demonstrating that the proposed scheme is more efficient in both respects than existing schemes
