Hybrid Post-Quantum TLS 1.3 for ISO 15118-20 Communications
Combining classic ECDH with ML-KEM key exchange to achieve defense-in-depth during the transition period without breaking protocol compliance.
Packet Fragmentation Handling
Lattice keys are larger than ECC keys. Optimized HomePlug Green PHY link adapters prevent packet drops during fragmented TLS ClientHello exchanges.
- Hybrid X25519 + ML-KEM-768 key exchange.
- Handshake latency kept below 250 milliseconds over PLC lines.
- Automated fallback to classic suites if EVSE lacks PQC support.
- Zero unauthenticated cleartext transmission of grid telemetry.
