The advancement of technology and the expansion of IoT have reduced the gap between humans and machines in recent years. IoT systems are always vulnerable to attacks from devilish minds on Earth, and these might be sufficient to bring down a whole company in the marketplace. There are incidents of smart car thefts that occur covertly due to a well-known exploit called the relay attack. It's crucial to properly neutralise the relay attack since there are situations where multiple users are operating an automobile at once. By leveraging the current innovation, we aim to mitigate the method that cybercriminals use to easily break into vehicles. The most serious issue is the 'Relay Attack', which could use a latent keyless entry system weakness to start a Passive Keyless Entry System vehicle. An adversarial attacker gains entry to a mechanised vehicle by intercepting radio messages and relaying them back to the vehicle. The effect of this assault and the misfortune is huge. In this work, an amalgamation of network security, the Internet of Things and machine intelligence is considered to formulate a countermeasure for relay attacks. The proposed system ensures the security of vehicles that work on a passive keyless entry system by authenticating multiple drivers through the CART algorithm.
