Post-Quantum
Engineering
We implement, audit, and deploy NIST FIPS 203 in production today — not on a roadmap. Hybrid handshake construction, side-channel hardening, KAT-gated CI across heterogeneous client platforms.
From paper to production
Translating NIST drafts into shippable code is non-trivial. We provide reference implementations, validate against the NIST KAT files, and integrate with existing TLS/Noise/Signal-style stacks.
- ML-KEM-1024, ML-DSA target (FIPS 204)
- Hybrid X25519/X448 combiners
- Constant-time verification on target CPUs
Hybrid handshake design
Pure PQ is risky if a primitive breaks; pure classical is doomed to harvest-now-decrypt-later. Hybrid construction combines both via HKDF, providing defense-in-depth with negligible overhead.
- HKDF combiner with domain-separated labels
- Forward secrecy under quantum and classical adversary
- Compatible with TLS 1.3 hybrid drafts
KAT-gated cross-platform CI
Whenever a new platform joins the stack, KAT vectors regenerated from BouncyCastle (or a reference implementation) gate the build. No platform divergence ever ships.
- BouncyCastle Java reference dumper
- Android, iOS, Desktop verify byte-equal
- Public KAT vector packs for client validation
