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.
