Post-Quantum Cryptography
Protecting family communications against tomorrow's quantum computers. Deploying ML-KEM and ML-DSA today for harvest-now-decrypt-later resilience.
The Quantum Threat
Quantum computers will eventually break the encryption protecting today's communications. When they do, every message you've ever sent could be decrypted retroactively. This is known as the "harvest now, decrypt later" threat.
For families navigating sensitive health information, legal proceedings, or simply valuing their privacy, this threat is existential. We cannot wait until quantum computers arrive to upgrade our security.
Timeline Concerns
- • NIST estimates cryptographically-relevant quantum computers within 10-20 years
- • Adversaries are already harvesting encrypted data for future decryption
- • Healthcare and legal data have decades-long sensitivity periods
Our PQC Implementation
P31 Labs has deployed NIST-approved post-quantum cryptography across our entire infrastructure. We're among the first production implementations for consumer-facing applications.
ML-KEM-768
Module Lattice-based KEM
Module Learning With Errors Key Encapsulation Mechanism. NIST FIPS 203 approved. Provides quantum-resistant key exchange for all family mesh communications.
- ✓ NIST FIPS 203 compliant
- ✓ 768-bit security parameter
- ✓ Hybrid with ECDH P-256
ML-DSA-65
Module Lattice-based Digital Signature
Module Learning With Errors Digital Signature Algorithm. NIST FIPS 204 approved. Quantum-resistant authentication for all mesh identity verification.
- ✓ NIST FIPS 204 compliant
- ✓ 65-bit security parameter
- ✓ Small signature sizes
Technical Specifications
Hybrid Key Exchange
We use a hybrid approach combining classical and post-quantum algorithms. This provides defense-in-depth: even if a vulnerability is found in one algorithm, the other protects the communication.
Shared Secret = KDF(ML-KEM-768(shared_secret) || ECDH-P256(shared_secret))
