Quantum Key Distribution Technology

Quantum Key Distribution Technology

By releasing a commercial Request for Proposal, the Indian Army has begun the process of acquiring Quantum Key Distribution (QKD) technology created by a cybersecurity firm based in Bengaluru (RFP).

About QKD:

It is a secure communication technique that makes use of a cryptographic protocol involving a number of quantum mechanical elements.

Process:

  • The technique enables two communicating sides to generate random secret keys that are known only to them and shared by the two of them.
  • This ensures that only the communicating sides can use the keys to encrypt and decode messages, resulting in very highly secure communication.
  • Critical data, sound, or video between the endpoints is encrypted using unhackable encryption keys created using QKD to help construct a non-hackable quantum channel.

Key exchange:

  • The fundamental element in this is how encryption keys are distributed. Sharing keys across wireless or wired connections necessitates encryption, which in turn necessitates pre-sharing of encryption keys.

Agencies in India dealing with QKD:

  • The DRDO has launched numerous efforts to advance this technology.
  • India is prepared to join the league of world leaders with its own, more sophisticated quantum communication technology to provide its armed forces with high-end defence as the nation celebrates "Azadi Ka Amrit Mahotsav”.

Significance

  • Security agencies will be able to design an appropriate quantum communication network with an indigenous technology backbone thanks to this technology.
  • Currently, highly secure military grade communications are possible.

Secure communications are essential for several civilian applications as well as for global defence and strategic organizations.
