Written by: Susan Brown - Founder & CEO Zortrex - 18th January, 2025

As the advent of quantum computing accelerates, the need for post-quantum cryptographic (PQC) solutions has become an urgent priority. Traditional cryptographic systems, which rely on constructs like keys, salts, and hashes, are at significant risk of being compromised by quantum computers. Recognising this imminent challenge, our team has developed and tested a groundbreaking system for secure Vehicle-to-Everything (V2X) communication a cornerstone of modern and future connected vehicles.

Our Simulation of Quantum-Secured V2X Messaging demonstrates the feasibility of post-quantum cryptography in high-throughput environments and showcases a novel approach that fundamentally departs from traditional cryptographic techniques.

Simulation Overview and Results

The simulation evaluated the scalability and performance of our post-quantum cryptographic system under real-world-like conditions:

• Fleet Size: 1,000 simulated vehicles.
• Cryptographic Methodology: A proprietary post-quantum approach that avoids the use of keys, salts, or hashes, ensuring enhanced resilience against quantum attacks.
• Performance Highlights: Throughput: Successfully secured and broadcast 1,000 V2X messages in ~2 seconds (~500 messages per second). Daily Capacity: At this rate, the system could process approximately 43,200,000 messages per day, demonstrating exceptional scalability. Stability: The system handled all requests with zero errors or delays, validating its robustness. Efficiency: Cryptographic operations were completed within microsecond-scale, meeting real-time communication benchmarks.

What Sets This System Apart?

1. Non-Mathematical Cryptographic Approach: Our system bypasses vulnerabilities inherent in mathematical constructs like RSA and ECC, which quantum computers can efficiently break. By leveraging novel methodologies, this approach offers unmatched resilience to quantum threats.
2. Scalability and Performance:
3. Future-Ready Design: This system is built with forward compatibility in mind, addressing the imminent risks posed by quantum computing while maintaining compatibility with modern V2X infrastructure.
4. Potential for Drone Fleets: The system’s ability to process 43.2 million messages per day highlights its potential for use in drone fleet management. Real-time communication is critical for drone swarms, urban delivery systems, and surveillance networks, where secure, high-throughput messaging ensures safe and coordinated operations. The microsecond-level efficiency and high scalability make this system an ideal candidate for scaling drone operations in dense airspace or high-demand scenarios.
