DRDO tests quantum key distribution platform
खबर में क्यों?
Eavesdropping leaves a trace: the quantum principle behind DRDO's QKD test that GS-III Science and Technology tests
The Defence Research and Development Organisation configured and tested its Quantum Key Distribution platform on 14 October 2026. Quantum key distribution uses the laws of quantum mechanics to share encryption keys, and any attempt to eavesdrop disturbs the quantum state and can therefore be detected.

मुख्य तथ्य
Remember these
- DRDO configured and tested its Quantum Key Distribution (QKD) platform on 14 October 2026.
- QKD uses the laws of quantum mechanics to share encryption keys between two parties.
- Any attempt to eavesdrop disturbs the quantum state, so the interception can be detected.
- QKD secures the key exchange; the data itself is then encrypted with the shared key.
- DRDO is the Defence Ministry's research body for defence technologies.

How the exam will ask it
प्रीलिम्स
- Quantum Key Distribution uses principles of quantum mechanics to share encryption keys between two parties.
- In QKD, an attempt to eavesdrop on the quantum channel disturbs the quantum state and can be detected.
- DRDO functions under the Ministry of Defence and develops defence technologies.
मेन्स
GS-III (Science and Technology; Internal Security): Growing quantum computing capability threatens conventional public-key encryption, making secure communication a strategic concern. QKD offers detectable-eavesdropping key exchange, and DRDO's platform test supports indigenous secure military and government links under the National Quantum Mission. The way forward lies in scaling fibre and satellite QKD, setting standards, and building domestic hardware to reduce import dependence.
Quick recall
Answer before you reveal
With reference to Quantum Key Distribution (QKD), consider the following statements:
- It uses principles of quantum mechanics to share encryption keys between two parties.
- An attempt to eavesdrop on the quantum channel disturbs the quantum state and can be detected.
Which of the statements given above is/are correct?
- 1 only
- 2 only
- Both 1 and 2
- Neither 1 nor 2
उत्तर देखें
उत्तर: C — Both 1 and 2 is correct. Both statements are correct. QKD relies on quantum mechanics, and eavesdropping alters the quantum state, which reveals the interception.
