Quantum-Safe Security for 5G Networks

Abstract

This research investigates post-quantum cryptography's implementation and performance impact in 5G networks using the free5GC platform. Developed a comprehensive framework incorporating CRYSTALS-Kyber algorithms through Docker-containerized network functions and OpenSSL integration. Testing with two virtualized servers (2 vCPU, 4 GB RAM) demonstrated that quantum-resistant security can be achieved without compromising network performance requirements. Results show Kyber variants maintain latency well below 1ms (Kyber512: 0.059702s, Kyber1024: 0.051873s), with manageable bandwidth requirements (Kyber512: 682.99 bytes/packet, Kyber1024: 775.79 bytes/packet). Kyber1024 achieved superior throughput (14,958.19 bytes/second) compared to traditional X25519 (10,496.87 bytes/second. A practical implementation framework through Docker containers with custom Python scripts for performance analysis enables organizations to merge quantum-resistant security with operational network efficiency. This research has developed structures that secure telecommunications frameworks from threats caused by advanced quantum computing techniques.
