The Internet of Vehicular Things (IoVT) field is expanding rapidly through the application of advanced technologies that enable the connection of vehicles, infrastructure , and other entities to the Internet. In addition to generating valuable data-driven insights, this development offers many advantages, such as enhancing safety, efficiency, convenience, and delivering personalized services. IoVT data is sensitive and requires secure storage and transmission, and if this information falls into the wrong hands, it could be misused for malicious purposes such as theft, fraud, or stalking. An unauthorized access to IoVT data has the potential to jeopardize the safety and security of vehicles and their passengers. Therefore, it is vital to establish a robust security mechanism to guarantee secure communication, ensure vehicle safety and integrity, facilitate efficient traffic management, provide emergency services, protect privacy and data, prevent unauthorized access, and to ensure compliance with regulations. To address the security requirements of IoVT, this research presents an innovative group-based authentication & key agreement protocol designed explicitly for IoVT, and strives to achieve the core security objectives within the 5G networks. The proposed protocol successfully fulfills crucial security objectives in IoVT, including subscriber privacy, key confirmation , authentication & key agreement, perfect forward/backward key secrecy, and session unlinkability. The security claims of the protocol underwent thorough examination using the AVISPA tool and BAN logic, confirming its ability to withstand diverse cryptographic attacks. Additionally, a mathematical investigation has affirmed the protocol’s suitability for IoVT devices, as it successfully achieves its objectives while minimizing signaling overhead, bandwidth usage, and computational burden.

The vehicle ad-hoc network (VANET) is a crucial technology that will play a significant role in shaping the future of transition systems, which is widely used as a subset of ad-hoc networks. VANET aims to ensure driver safety by establishing independent communication with nearby vehicles. A key requirement for successful data transmission is cooperation among nodes, as factors such as high mobility, limited radio range, signal fading, and noise lead to packet loss. Security issues in vehicle ad-hoc networks have recently become a major concern. One factor that affects security is the presence of abusive nodes in the network. Like selfish nodes, they are reluctant to share their sources with their neighbors and try to keep their property. The misbehavior of malicious nodes includes dissemination of false traffic information, false location information, and redirection of packets to a wrong path, retransmission of packets, impersonation, so these nodes should be tracked down to ensure the operation of the network. This article provides a complete summary of various research works proposed to detect selfish and malicious nodes and isolate them from honest vehicles. This review article first describes the types of attacks. It then presents the methods proposed by researchers to deal with uncooperative nodes and compares their performance based on parameters such as the number of misbehaving nodes detected, overhead, throughput, layer involved in the attacks.

“…Authentication in large networks, however, requires key management. Managed environments are those where a common trusted center manages keys [ 17 – 25 ]. A network node that does not have impenetrable hardware and authentication infrastructure, such as in gaming environments without a trusted center to control the network, can compromise the credibility of the network.…”

SGHRP: Secure Greedy Highway Routing Protocol with authentication and increased privacy in vehicular ad hoc networks

VANETs are networks of connected intelligent vehicles that can communicate with each other, as well as with infrastructure and fixed roadside equipment. As a result of the lack of fixed infrastructure and open-access environment, security is crucial when sending packets. Secure routing protocols have been proposed for VANETs, but most are focused on authenticating nodes and creating a secure route, without considering confidentiality after the route is created. Using a chain of source keys validated by a one-way function, we have proposed a secure routing protocol called Secure Greedy Highway Routing Protocol (GHRP), which provides increased confidentiality over other protocols. As part of the proposed protocol, the source, destination, and intermediate nodes are authenticated using a hashing chain in the first stage, and in the second stage, one-way hashing has been used to increase data security. In order to resist routing attacks such as black hole attacks, the proposed protocol is based on the GHRP routing protocol. The proposed protocol is simulated using the NS2 simulator, and its performance is compared with that of the SAODV protocol. Based on the simulation results, the proposed protocol performs better than the mentioned protocol in terms of packet delivery rate, overhead, and average end-to-end delay.
