Overview
- DRDO said on Wednesday that it configured and tested a Quantum Key Distribution platform on the live operational network at the Proof & Experimental Establishment (PXE) in Chandipur to protect telemetry and observation data from artillery and armoured-weapon trials.
- The system was developed under DRDO’s MCC cluster with production partner Taqbit Labs, and DRDO described the test as demonstrating eavesdropping detection and providing 'unconditional security' for key distribution.
- Quantum Key Distribution uses quantum properties to create and share encryption keys so any interception disturbs the quantum signals and can be detected, a feature DRDO says makes the link resilient even if adversaries try to tap transmissions.
- Practical implications include nearer-term protection for engineers and range officers who send real-time sensor and performance data during weapons tests, and reduced risk of leaking sensitive technical information that could compromise evaluations.
- The live-range test follows July’s fibre-based field trials and earlier DIA‑CoE demonstrations; DRDO frames the work as foundational for scaled, multi‑hop indigenous quantum networks, but the agency’s security claims are reported statements and not independently verified in the coverage.
