Description:Quantum-Resistant Keyless Entry System Utilizing Secure Cryptographic Protocols
TECHNICAL FIELD
[0001] The present innovation relates to the field of keyless entry systems utilizing quantum-resistant cryptographic protocols for secure authentication in vehicles and access control systems.

BACKGROUND

[0002] Keyless entry systems have become a standard feature in modern vehicles, offering user convenience by enabling contactless access and ignition. However, these systems are increasingly vulnerable to security threats such as relay attacks, key cloning, and cryptographic weaknesses. Relay attacks exploit the proximity-based authentication mechanism by extending the communication signal between the key fob and the vehicle, allowing unauthorized access even when the key fob is far from the car. Similarly, key cloning enables attackers to replicate a legitimate key signal if the cryptographic protocol is weak, bypassing security measures. Furthermore, advancements in quantum computing pose a significant threat to traditional encryption methods like RSA and ECC, which could eventually be broken using quantum algorithms.

[0003] To mitigate these security risks, users currently rely on alternative solutions such as signal-blocking pouches, two-factor authentication, or encrypted key fobs. While these methods provide temporary protection, they come with notable drawbacks. Signal-blocking pouches are inconvenient and not foolproof, two-factor authentication introduces delays in user experience, and current encryption methods remain vulnerable to emerging quantum threats.

[0004] The present invention, a Quantum-Resistant Keyless Entry System Utilizing Secure Cryptographic Protocols, overcomes these limitations by integrating post-quantum cryptographic (PQC) algorithms that are resilient to quantum attacks. Unlike conventional keyless entry systems, it employs lattice-based cryptography, hash-based signatures, and code-based encryption to prevent unauthorized access, even against advanced computational threats. Additionally, the invention features dynamic key rotation, challenge-response authentication, ultra-wideband (UWB)-based distance verification, and AI-driven anomaly detection to counter relay attacks and key cloning. This approach ensures tamper-proof, future-proof security without compromising user convenience. By leveraging quantum-resistant encryption and adaptive security mechanisms, the invention provides a robust, scalable, and long-term cyber security system for automotive, IoT, and access control systems, setting it apart from existing technologies.
