Neural-Plasma Waveform Purification and Physical-Layer Resilience for Post-Quantum Cryptography in 10 Gbps+ Space-Terrestrial Links

This preprint presents a dual-layer physical-layer hardening framework for NIST post-quantum cryptography (ML-KEM/Kyber and ML-DSA/Dilithium) in 10 Gbps+ space-terrestrial links. The Neural-Plasma Algorithm (NPAP) acts as a physics-informed neural operator that pre-heals waveform shredding and neural erosion caused by orbital jitter, Gaussian noise, and radiation-induced errors before signals reach the decryption gate. Topological Silence Zones are established at the 1.022 MeV electron-positron pair-production resonance using distributed sub-wavelength plasmonic meta-atoms (10¹⁰ yr lifetime). Monte-Carlo simulations demonstrate more than 10¹³× BER improvement under GEO-typical conditions. The architecture directly addresses U.S. Department of Energy Genesis Mission Challenges #23 (Safeguarding Nuclear Materials from Proliferation Threats) and #24 (Nuclear Enterprise Streamlining & Safety) by delivering information-theoretic, distortion-resistant security for nuclear command-and-control and grid telemetry in contested LEO/GEO environments. All components are compatible with 2026-era COTS and space-qualified hardware. This work expands the TINA (Truth-Invariant Neural Architecture) blueprint from theoretical foundations into deployable orbital security systems.
