News: Defence Research and Development Organisation(DRDO) has successfully demonstrated communication between its two labs using Quantum Key Distribution(QKD) technology.


  • Quantum Key Distribution(QKD): It is primarily a mechanism to undertake secure communication which utilises a cryptographic protocol involving various components of quantum mechanics.
  • Process: The technology enables two communicating sides to come up with random secret keys shared by both of them and known exclusively to them so only they can use it to encrypt and decrypt messages, thus achieving highly-secure communication.
  • Developed by: The technology has been developed by two DRDO facilities, Centre for Artificial Intelligence and Robotics (CAIR), Bengaluru and DRDO Young Scientists’ Laboratory – Quantum Technology (DYSL-QT),Mumbai.
