Towards Quantum-Resilient Log Integrity in 5G/6G Mobile Network Protocol Analysis

As 5G networks mature and 6G technologies emerge, the integrity of log data becomes increasingly critical for network security, forensic analysis, and regulatory compliance. The advent of quantum computing poses unprecedented threats to current cryptographic mechanisms protecting log integrity in mobile network infrastructures. This paper presents a comprehensive analysis of quantum threats to existing log integrity systems and proposes a novel quantum-resilient framework for maintaining tamper-evident logging in 5G/6G networks. We examine post-quantum cryptographic solutions, including lattice-based algorithms, blockchain integration, and hybrid approaches combining traditional and quantum-safe mechanisms. Our framework addresses key challenges including forward security, crash recovery, and real-time performance requirements while maintaining compatibility with existing 5G/6G protocol stacks. Through theoretical analysis and performance evaluation, we demonstrate that quantum-resilient log integrity can be achieved without compromising network performance, providing a foundation for secure next-generation mobile communications.
