  • •Quantum computers could break current encryption by 2029, posing risks to digital trust.
  • •Countries in Asia-Pacific show varying levels of readiness for post-quantum cryptography.
  • •Governments must take proactive measures to ensure the security of critical infrastructure.

As quantum computing advances, existing public-key cryptographic systems face imminent threats, potentially being compromised by 2029. The 'Harvest Now, Decrypt Later' strategy allows adversaries to collect encrypted data for future decryption. The CCAPAC Annual Report 2026 highlights varying levels of quantum readiness across Asia-Pacific countries, with Australia, China, and India making notable progress. Post-quantum cryptography (PQC) standards established by NIST in 2024 provide a framework for transitioning to more secure algorithms. However, many organizations remain unaware of vulnerable algorithms in use, and legacy systems may require replacement rather than simple updates. Governments must lead in setting expectations and facilitating industry transitions to ensure the security of critical infrastructure and digital services.

Common questions

What is post-quantum cryptography?
Post-quantum cryptography (PQC) refers to cryptographic algorithms designed to be secure against the capabilities of quantum computers.
Which countries are leading in quantum readiness?
Australia, China, and India are noted for their significant progress in quantum readiness according to the CCAPAC report.
What should organizations do to prepare?
Organizations should assess their current cryptographic systems and begin planning for the transition to post-quantum algorithms.
