Quantum Key Distribution tech tested by DRDO successfully between Vindhyachal & Prayagraj

A team of scientists, for the first time in the country, from the Defence Research and Development Organisation (DRDO) and the Indian Institute of Technology (IIT) Delhi successfully demonstrated a Quantum Key Distribution link between Prayagraj and Vindhyachal in Uttar Pradesh, spanning over 100 kilometres.

KEY POINTS:

• This technological breakthrough was accomplished using a commercial-grade optical fibre that was already on the market. The country has shown domestic safe key transfer technology for bootstrapping military grade communication security key hierarchy, according to the DRDO.
• This technological advance was made possible by the use of a commercially available optical fibre. According to the DRDO, the country has shown a domestic secure key transfer technique for bootstrapping military grade communication security key hierarchy.
• G Satheesh Reddy, Secretary of Defense R&D and Chairman of DRDO, thanked the scientists and professors of DRDO and IIT Delhi for the successful demonstration of this technology. He noted this in his speech to the scientific community as one of the shining examples of synergistic research between the DRDO and the Indian Institute of Technology, Delhi.
• Professor Rangan Banerjee, Director of IIT Delhi, also commended the DRDO faculty and scientists involved in this breakthrough for their dedicated initiatives to strengthen the country’s technological capability.

 Quantum key distribution:

Quantum key distribution is a secure communication tech method that uses quantum physics to construct a cryptographic protocol. It allows two parties to generate a shared secret key that is only known to them and can be used to encrypt and decrypt messages.
