The Solution
One network, keys guaranteed by physics
A proposed sovereign quantum key fabric: a space segment, a ground segment, and the architecture that ties them together.
Solution
One network, keys guaranteed by physics
A proposed sovereign space-to-ground quantum key fabric, built in two segments.
Defence in depth: QKD where quantum links exist, post-quantum crypto everywhere else. One auditable key fabric, quantum-safe from day one.
Payload-class hardware, not lab benches: compact optical terminals sized for small LEO satellites.
Architecture
Space-to-ground key delivery, end to end
As you scroll, follow a quantum key from orbit to the endpoints that consume it.
Stage 01
Satellite
A compact LEO payload generates entangled photon pairs. It never holds the key, so it never has to be trusted.
Stage 02
Quantum photon
Single photons carry the key downward. Any interception disturbs them and is detected, so eavesdropping announces itself.
Stage 03
Optical ground station
AI-driven pointing, pass scheduling and cloud-cover prediction maximise key yield through the atmosphere.
Stage 04
Fiber backbone
Metro fibre QKD rings on MDI-QKD links distribute keys across cities, closing detector side-channels.
Stage 05
End users
Defence, finance, grid and government endpoints draw keys from one auditable fabric.
No trusted satellite
Entanglement-based links mean the satellite never holds the key, so there is nothing on board to steal.
Graceful degradation
Clouds or jamming never break security, because post-quantum cryptography carries the fabric when quantum links drop.
Every key audited
QBER, origin link and consumption are logged end-to-end for certification and accountability.
Pillars
Built to leapfrog, not to copy
Entanglement-based QKD
Keys born from entangled photon pairs. The satellite never knows the key, so there is nothing on board to steal.
MDI-QKD ground links
Measurement-device-independent protocol closes detector side-channels and slashes the trusted-relay count.
AI-run operations
Our AI heritage applied to optics: cloud-cover prediction, pass scheduling and beacon pointing maximise key yield.
Hybrid PQC fallback
NIST post-quantum algorithms (ML-KEM, ML-DSA) keep every endpoint quantum-safe even where no quantum link exists yet.
Indigenous & auditable
Protocols, firmware and key management designed and reviewed in India, with no imported black boxes in the trust chain.
Audit-ready telemetry
Per-key provenance, with QBER, source link and consumption logged for certification and accountability.
Physics-guaranteed keys · quantum-safe from day one · sovereign by design.
