Additionally, VANETs facilitate efficient emergency response, prompt incident documentation, and coordinated evacuation plans during critical situations. Utilizing VANET scalability and adaptability provides numerous benefits that can enhance \"the security and effectiveness of transportation networks\". Nevertheless, due to the open nature of VANETs, high node mobility, instability, and constantly changing network topology, security becomes a major concern when implementing VANETs. Within VANETs, vehicles demonstrate high velocities and recurrent disconnections, rendering them particularly vulnerable to potential attacks from adversaries seeking to acquire or manipulate valuable data within the network [4]. As shown in Figure 1, the attacker can send deceptive messages to the network or ask for the credential data of other users from the network. The blue lines indicate communication between vehicles or between RSUs, the dotted lines show vehicle-to-infrastructure communication and the red lines indicate dangerous information sent or received from a malicious node. To guarantee the security of Vehicular Ad-Hoc Networks (VANETs) and its various applications, particularly those related to safety, it is essential to verify the legitimacy of transmitted messages and the identities of their sources. Failure to do so could allow unauthorized vehicles to spread false information or engage in nefarious activities undetected, posing serious risks to transportation infrastructures and the safety of individuals using the roads. Consequently, the implementation of an authentication protocol in VANETs is imperative to thwart malevolent message transmission by adversaries and safeguard crucial network information [5]. The efficiency of message authentication in VANETs is crucial for maintaining safety. Any delay in authentication could lead to outdated or unreliable information being used to make driving decisions, potentially causing accidents. Quick authentication ensures that messages are verified rapidly, allowing for immediate action based on accurate and timely information. Delays in authentication can lead to a lag in the dissemination of critical safety information, increasing the risk of accidents due to delayed driver reaction times. Ensuring that authentication processes are efficient and meet the low latency requirements of VANET safety applications is essential to maintain the effectiveness and reliability of these systems in enhancing road safety. Most of the safety applications in VANETs exhibit low latency, typically around 100 ms. Consequently, there is a need for a proficient mechanism to validate incoming messages within a brief timeframe of 100 ms, prior to transmitting a fresh safety notification [6]. Figure 1: The vulnerability of VANET. Traditional methodologies for ensuring secure and authenticated message propagation, primarily relying on message encryption and key administration, are restricted to ensure secure message interchange solely among identified source and destination pairs. Due to the dynamic topology of VANETs, these methods cannot be directly implemented in these vehicular networks. The dissemination of messages within VANETs is also susceptible to insider assaults (i.e., assaults originating from authenticated VANET participants) that have the potential to breach the confidentiality of disseminated messages or disseminate malevolent messages. Consequently, the preservation of message integrity and authenticity during transmission within VANETs has emerged as a critical concern [7]. The Kerberos protocol functions as a robust authentication mechanism specifically crafted to enhance security within networks that are susceptible to breaches, utilizing session keys for transmitting data during the signaling phase as opposed to the principal key [8].
