Description:Encrypted V2X (Vehicle-to-Everything) Communication System
TECHNICAL FIELD
[0001] The present invention relates to an encrypted V2X communication system that ensures secure, authenticated, and privacy-preserving data exchange in intelligent transportation networks.

BACKGROUND

[0002] The rapid advancement of intelligent transportation systems (ITS) has led to widespread adoption of Vehicle-to-Everything (V2X) communication, enabling real-time data exchange between vehicles, infrastructure, networks, and pedestrians. V2X communication plays a crucial role in enhancing road safety, improving traffic efficiency, and supporting autonomous vehicle operations. However, the integration of wireless communication technologies in vehicular networks introduces significant security and privacy concerns. Cyber threats such as eavesdropping, message tampering, replay attacks, and spoofing pose risks to data integrity, confidentiality, and authenticity, potentially leading to traffic disruptions, safety hazards, and unauthorized surveillance of vehicle movements.

[0003] To address these challenges, existing security systems rely on Public Key Infrastructure (PKI), elliptic curve cryptography (ECC), and group-based authentication protocols to safeguard V2X communication. While these systesm provide a level of security, they suffer from high computational overhead, scalability issues, and privacy concerns due to the open nature of V2X communication. Centralized key management introduces single points of failure, making the system vulnerable to large-scale attacks. Additionally, traditional authentication methods lack efficient identity protection, exposing vehicles to tracking and profiling threats.

[0004] The present invention overcomes these limitations by introducing an encrypted V2X communication system that integrates hardware-based cryptographic processing, dynamic key management, AI-powered anomaly detection, and decentralized authentication mechanisms. Unlike conventional approaches, this system ensures end-to-end encryption, real-time threat detection, and low-latency message processing while maintaining scalability and efficiency. The system employs hybrid cryptographic techniques for secure key exchange, zero-knowledge proofs (ZKP) for authentication, and trust score-based access control to prevent unauthorized entities from accessing the network. Edge computing integration reduces reliance on cloud infrastructure, optimizing processing speed and minimizing delays.

[0005] The novelty of this invention lies in its multi-layered security architecture, which dynamically adjusts security measures based on real-time threat levels, ensuring seamless interoperability with existing V2X standards while providing enhanced privacy, security, and performance for next-generation vehicular communication networks
