Mission Quantum-Secure India: Fortifying National Infrastructure Against the Quantum Threat

The Union Cabinet’s approval of the ₹4,500 crore 'Mission Quantum-Secure India' marks a significant milestone in India’s journey toward technological sovereignty and national security. The mission focuses on transitioning the country’s Critical Information Infrastructure (CII)—specifically banking, power grids, and strategic communication channels—to Post-Quantum Cryptography (PQC). This proactive measure is designed to counter the 'Quantum Apocalypse,' a theoretical point where quantum computers become powerful enough to break current encryption standards like RSA and ECC. At the heart of this mission is the recognition that while functional quantum computers are still years away, the threat is immediate. Adversaries may engage in 'Harvest Now, Decrypt Later' tactics, where encrypted sensitive data is stolen today to be decrypted once quantum technology matures. By migrating to PQC, India aims to implement mathematical algorithms that are resistant to quantum attacks, ensuring long-term data integrity. This mission complements the existing National Quantum Mission (NQM), shifting the focus from development to the practical application of security protocols.
