Post-Quantum Cryptography
Essential infrastructure, not theory. The quantum computing timeline is accelerating. The threat is already active.
The Threat: Harvest Now, Decrypt Later (HNDL)
You do not need a fully fault-tolerant quantum computer today to compromise today's data. The primary threat vector is "Harvest Now, Decrypt Later" (HNDL). Adversaries — ranging from state actors to advanced persistent threats — are actively scraping and storing encrypted communications, health records, and legal data. The encryption holding that data is classical. When quantum hardware matures, that stored data will be decrypted retroactively.
If your sensitive data is transmitted today using legacy encryption, it is already compromised on a time delay.
The Hardware Timeline
We are exiting the NISQ (Noisy Intermediate-Scale Quantum) era and entering the era of logical error correction.
- ● Google Willow: Reached 105 qubits, demonstrating exponential error suppression — the first below-threshold error correction on a superconducting processor.
- ● IBM Starling: Targeted for 200 logical qubits by 2028.
Shor's algorithm is no longer just mathematical theory; the hardware required to execute it against RSA and ECC encryption is on a definitive roadmap. Scientists are calling this quantum technology's "transistor moment" — the transition from laboratory curiosity to engineered infrastructure.
The Regulatory Reality
The global infrastructure is already being forced to adapt. The European Union is mandating quantum-safe encryption standards by the end of 2026. This isn't a suggestion — it is a hard deadline for foundational digital infrastructure. Systems that fail to migrate will be fundamentally obsolete and legally non-compliant.
NIST has finalized Post-Quantum Cryptography standards: CRYSTALS-Kyber (ML-KEM, FIPS 203) for key encapsulation and CRYSTALS-Dilithium (ML-DSA, FIPS 204) for digital signatures. The migration path exists. The question is whether organizations will walk it before or after their data is compromised.
The P31 Labs Position: Sovereignty and Topology
Data Sovereignty
At P31 Labs, we build assistive technology and cognitive dashboards for neurodivergent individuals. The data these systems handle — real-time self-regulation metrics, internal state logs, medical timelines — is highly sensitive. We cannot rely on centralized, legacy security models to protect it.
Delta Topology
Centralized systems rely on a Wye (Star) topology, presenting a single point of failure. We are engineering our tools — including the Node One mesh hardware and the BONDING relay infrastructure — toward a Delta (Mesh) topology.
Our approach:
- Ed25519 device identity via NXP SE050 hardware security module (current)
- Migration path to lattice-based algorithms (ML-KEM / ML-DSA) via firmware OTA
- LoRa mesh (Meshtastic on SX1262) for serverless device-to-device communication
- No certificate authority dependency — each node maintains sovereign key material
Data sovereignty requires structural rigidity. We are building ahead of the curve because waiting for the centralized systems to upgrade is a vulnerability we cannot afford.

Build Sovereign, Stay Secure
Every P31 Labs tool is designed with cryptographic agility and post-quantum readiness from the ground up. Because the tools protecting our most vulnerable users cannot be rendered transparent by tomorrow's hardware.
