Quantum Communication using time-bin Quantum Key Distribution (QKD) scheme was performed under realistic conditions. The setup also demonstrated the validation of detection of a third party trying to gain knowledge of the communication.<\/p>\n\n\n\n
Quantum based security against eavesdropping was validated for the deployed system at over 12kms range and 10dB attenuation over fibre optic channel.<\/p>\n\n\n\n
Continuous wave laser source was used to generate photons without depolarization effect. The timing accuracy employed in the setup was of the order of picoseconds.<\/p>\n\n\n\n
The Single photon avalanche detector (SPAD) recorded arrival of photons and key rate was achieved in the range of kbps with low Quantum bit error rate.<\/p>\n\n\n\n
The work being done at DRDO will be used to enable start-ups and SMEs in the domain of Quantum information technologies.<\/p>\n\n\n\n
It will also serve to define standards and crypto policies that can leverage the QKD system in a unified Cipher Policy Committee (CPC) framework for more secure and pragmatic key management for current and future military cryptographic systems.<\/p>\n","protected":false},"excerpt":{"rendered":"
The Defence Research and Development Organisation (DRDO) successfully demonstrated communication between its two labs using Quantum Key Distribution (QKD) technology, which is a \u201crobust\u201d way to share encryption keys, said an official statement.
