DRDO tests quantum-secured communication system on live defence network

The Defence Research and Development Organisation (DRDO) has successfully tested a quantum-secured communication system on a live network used for artillery and armoured weapons testing, marking a step towards strengthening the security of sensitive military information.

The Quantum Key Distribution (QKD) platform was configured and tested on the live network of dynamic test ranges at the Proof and Experimental Establishment (PXE) in Chandipur, Odisha, DRDO said.

The system is designed to protect critical information, including real-time observations and telemetry collected during weapons trials. Telemetry refers to data automatically collected and transmitted from equipment to help scientists and engineers monitor its performance.

Unlike conventional encryption systems that rely on mathematical techniques, QKD uses principles of quantum physics to help two parties establish secure encryption keys. These keys are then used to encrypt and decrypt messages.

The technology can detect attempts to intercept quantum signals during key exchange. Such interference can alert the communicating parties to potential eavesdropping.

DRDO said the platform is designed to provide unconditional security for key distribution while incorporating eavesdropping detection. However, the security of the overall communication system also depends on its implementation and the protection of connected devices and networks.

The platform was developed under DRDO's Microelectronic Devices, Computational Systems and Cyber Security (MCC) cluster, in collaboration with its production partner, Taqbit Labs.
