1. INTRODUCTION

Vehicle theft has emerged as a significant concern in urban areas, with traditional security mechanisms failing to provide adequate protection against sophisticated theft techniques. Ex- isting vehicle security systems often rely on mechanical locks, alarms, and GPS tracking, which are either easily bypassed or reactive rather than preventive Jones et al. (2017).

This research focuses on the design and implementation of a radio-controlled car locking system that addresses these vul- nerabilities. The proposed solution integrates radio-frequency identification (RFID), rolling code encryption, and real-time monitoring to provide a robust security mechanism. By em- ploying encrypted signal transmission and real-time alerts, the system ensures that unauthorized access is promptly detected and prevented.

 

2. BACKGROUND

The rise in vehicle theft cases has prompted the development of advanced security systems. Traditional methods such as me- chanical locks and basic alarm systems are no longer sufficient due to advancements in theft techniques. Modern vehicles require security solutions that are proactive and capable of thwarting sophisticated attacks Wang et al. (2015) Huang and Xu (2017).

Radio-controlled car locking systems have gained attention due to their convenience and effectiveness. These systems use radio frequency (RF) signals to remotely lock and unlock vehicles. However, the security of these systems is often compromised by signal interception and replay attacks. To address these issues, rolling code encryption and real-time monitoring have been proposed as effective countermeasures Smith and Patel (2019).

 

3. SYSTEM COMPONENTS

The proposed system consists of several key components:

·        Central Control Unit: A microcontroller-based unit that processes incoming signals and controls the locking mechanism.

·        RF Communication Module: Handles the transmission and reception of encrypted RF signals.

·        Power Management Unit: Ensures uninterrupted opera- tion with a battery backup system.

·        Mobile Application Interface: Allows users to monitor and control the system in real-time.

·        Sensors and Actuators: Detects unauthorized access attempts and operates the locking mechanism Kumar and Jain (2020) Brown and Davis (2019).

 

4. METHODOLOGY

The proposed system follows an agile development ap- proach, incorporating iterative design, testing, and validation. The core components of the system include:

·        Radio-Controlled Locking Mechanism: Uses encrypted RF signals to operate the vehicle lock remotely.

Results demonstrated a significant improvement in security, with en- crypted communication preventing unauthorized access at- tempts. Comparative analysis with traditional security systems highlighted the advantages of integrating rolling code encryp- tion and real-time monitoring.

1)    Performance Evaluation

The system’s performance was evaluated based on several criteria, including response time, reliability, and security. The response time of the system was measured from the moment a signal was sent to the time the locking mechanism was activated. The system demonstrated a quick response time, ensuring timely locking and unlocking of the vehicle.

The reliability of the system was tested by subjecting it to various environmental conditions, including high RF interference and power outages. The system maintained con- sistent performance, with the backup power solutions ensuring uninterrupted operation during power failures.

2)    Security Analysis

The security analysis involved testing the system against various attack vectors, including signal hijacking, relay at- tacks, and brute force attempts. The rolling code encryption effectively mitigated replay attacks, while the encrypted RF communication ensured that signals could not be easily inter- cepted or duplicated. Real-time alerts provided an additional layer of security by notifying the vehicle owner of any unauthorized access attempts.

3)    User Experience

User feedback was collected to evaluate the usability and convenience of the system. The mobile application interface was rated highly for its intuitive design and ease of use. Users appreciated the real-time alerts and the ability to control the locking mechanism remotely. The backup power solutions were also well-received, as they ensured uninterrupted opera- tion of the system.

4)    Limitations and Future Work

While the proposed system offers significant improvements in vehicle security, there are some limitations that need to be addressed. The reliance on RF communication makes the system vulnerable to jamming attacks, which can disrupt the signal transmission. Additionally, the cost of implementing the system may be a barrier for widespread adoption.

Future work will focus on enhancing the system’s resilience to jamming attacks by incorporating alternative communica- tion channels such as Bluetooth and Wi-Fi. Further research will also explore the integration of artificial intelligence (AI) for threat detection and blockchain technology for secure access control. These enhancements aim to provide a more robust and comprehensive security solution.

 

6. CONCLUSION

The proposed solution not only prevents unauthorized access but also reduces reliance on traditional security measures that are easily compromised. Future work will explore fur- ther enhancements, including AI-based threat detection and blockchain-based access control for improved security mea- sures.
