Securing India’s Digital Future: DST Roadmap for Quantum-Safe Cryptography

The roadmap suggests a multi-layered approach: identifying vulnerable systems, developing indigenous PQC algorithms, and establishing a regulatory framework for migration. This is particularly crucial for India’s 'Digital India' initiative, where platforms like Aadhaar, UPI, and DigiLocker rely heavily on robust encryption. The report also aligns with the objectives of the National Quantum Mission (NQM), which seeks to make India a global leader in quantum technologies. However, the transition poses significant challenges, including the high cost of upgrading legacy hardware, the need for specialized talent, and the risk of 'harvest now, decrypt later' attacks, where adversaries steal encrypted data today to decrypt it once quantum computers become available. The DST task force advocates for 'crypto-agility'—the ability of a system to switch between different cryptographic algorithms without major infrastructure overhauls. UPSC Relevance: This development is highly relevant for GS Paper III under Science and Technology and Internal Security. It provides a concrete example of how emerging technologies necessitate policy shifts in cyber security and digital governance. Aspirants can use this roadmap to discuss India's preparedness for 'Industry 4.0' and the strategic importance of technological sovereignty in the quantum era.
