Intelligence at the edge
An on-device NPU runs anomaly detection, intrusion analytics and predictive maintenance without a cloud round-trip, keeping decisions fast and data sovereign.
Technology
The science behind quantum-safe security
QUANSHIELD combines quantum key distribution, post-quantum cryptography, edge analytics and audit logging in one gateway.
Quantum
Quantum computing & security
We use quantum physics for security and optimisation, distributing keys whose interception is physically detectable and solving problems classical systems cannot match.
- QKD: quantum key distribution over fibre & free-space.
- QRNG: true entropy from a quantum source.
- QML & VQC: quantum machine learning & variational circuits for forecasting and optimisation.
Information-theoretic security
QKD's security rests on the laws of physics, not on computational hardness. An eavesdropper necessarily disturbs the quantum state and is detected.
NIST-standardised
ML-KEM (key encapsulation) and ML-DSA (digital signatures) are the algorithms standardised for the post-quantum era, implemented here in a dedicated hardware accelerator.
Post-Quantum Cryptography
Cryptography that survives quantum
Where QKD links are not available, post-quantum cryptography keeps every channel protected and closes the harvest-now-decrypt-later window everywhere.
- ML-KEM: lattice-based key encapsulation.
- ML-DSA: lattice-based digital signatures.
- Hardware crypto accelerator, secure boot & TPM 2.0 root of trust.
Trust without intermediaries
Distributed ledger and smart contracts provide tamper-evident settlement for secure P2P energy trading and auditable transactions.
FAQ
Quantum security, explained
Adversaries record encrypted data today and store it to decrypt once a cryptographically relevant quantum computer exists. Long-lived defence, financial and infrastructure data is already at risk, so quantum-safe protection has to start before quantum computers mature.
QKD uses quantum physics to distribute keys and detect any eavesdropping. PQC uses mathematical algorithms believed to resist quantum attacks. QUANSHIELD uses both in a hybrid model so protection does not drop.
QUANSHIELD implements NIST-standard ML-KEM for key encapsulation and ML-DSA for digital signatures, accelerated in dedicated hardware alongside a TPM 2.0 root of trust.
Yes. The gateway speaks IEC-61850, Modbus, DNP3, CAN/CAN-FD, OPC-UA, MQTT and SNMPv3, with multi-network connectivity for existing industrial and utility environments.
