ABSTRACT.

A quantum-resilient approach to multipath QUIC telemetry using adaptive Post-Quantum Cryptography (PQC). This work introduces dynamic key-encapsulation switching mechanisms based on network conditions and packet error rates. By combining Kyber key exchange with learning-based routing and adaptive forward error correction (FEC), the pipeline minimizes decryption latency overhead while ensuring absolute security against harvest-now-decrypt-later adversaries.

METHODOLOGY.

We implemented an adaptive cryptographic selector within the multipath QUIC handshake. As telemetry links change, the system shifts between different PQC parameter strengths (Kyber-512/768/1024) while dynamically adapting FEC code rates to maintain performance.
