Post-quantum cryptography (PQC) has significant application prospects in intelligent transportation systems (ITS), as these systems increasingly rely on secure data transmission, real-time decision-making, and connectivity. Quantum computers pose a threat to traditional cryptographic algorithms, and PQC ensures long-term security against quantum attacks.
Secure Vehicle-to-Everything (V2X) Communication: ITS relies on V2X communication for safety and efficiency, such as vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) interactions. PQC can protect these communications from quantum threats, ensuring data integrity and confidentiality. For example, a self-driving car exchanging sensor data with traffic lights or other vehicles needs quantum-resistant encryption to prevent interception or tampering.
Protection of Critical Infrastructure: ITS infrastructure, including traffic management systems and toll collection networks, stores sensitive data. PQC can safeguard databases and communication channels from quantum-enabled attacks, preventing unauthorized access or data breaches. For instance, quantum-resistant algorithms can secure toll payment systems, ensuring transaction integrity.
Data Privacy in Autonomous Vehicles: Autonomous vehicles generate and process vast amounts of data, including location, speed, and passenger information. PQC ensures that this data remains private and secure, even against future quantum threats. For example, a ride-sharing service using AI-driven route optimization must protect user data with quantum-safe encryption.
Cloud-Based ITS Services: Many ITS solutions leverage cloud computing for data storage and analytics. Tencent Cloud offers quantum-resistant cryptographic solutions to protect cloud-hosted ITS data, ensuring compliance with future security standards. For example, a smart city’s traffic monitoring system hosted on Tencent Cloud can use PQC to secure video feeds and analytics data.
By integrating PQC into ITS, transportation networks can achieve robust security against emerging quantum threats, ensuring reliability and trust in smart mobility solutions.
