Overview

  • The joint CERT-In and SISA report 'Transitioning to Quantum Cyber Readiness' confirms quantum computers have moved from research labs into practical applications and highlights urgent cybersecurity risks.
  • The report warns that quantum machines could break widely used encryption algorithms like RSA and ECC, enabling attackers to launch "harvest now, decrypt later" data breaches.
  • IT Secretary S Krishnan recommended that organizations allocate 15–20% of software and IT spending to cybersecurity to build resilience against quantum threats.
  • Officials acknowledged that India’s cybersecurity ecosystem is not yet mature enough for mandatory sourcing of homegrown tools and requires stronger market demand first.
  • CERT-In Director General Sanjay Bahl urged immediate updates to security frameworks and adoption of quantum-resistant cryptography to safeguard digital infrastructure.
