GS-III QUANTUM KEY DISTRIBUTION S&T

GS-III : S&T


QUANTUM KEY DISTRIBUTION (QKD):

  • The Defence Research and Development Organisation (DRDO) successfully demonstrated communication between its two labs using Quantum Key Distribution technology.
  • The Defence Research and Development Laboratory (DRDL) and The Research Centre Imarat (RCI) were the two labs that participated in this demonstration.

About this technology:

  • Quantum computing refers to a new era of faster and more powerful computers, and the theory goes that they would be able to break current levels of encryption.
  • QKD works by using photons — the particles which transmit light — to transfer data.
  • QKD allows two distant users, who do not share a long secret key initially, to produce a common, random string of secret bits, called a secret key.

Significance of this technology:

  • The encryption is “unbreakable” and that’s mainly because of the way data is carried via the photon.
  • A photon cannot be perfectly copied and any attempt to measure it will disturb it.
  • This means that a person trying to intercept the data will leave a trace.
