Singapore

NIST bloc Standard-contextualiser

Singapore's transition is led by the Cyber Security Agency, which in October 2025 opened a public consultation, running to the end of December 2025, on a Quantum-Safe Handbook, a Quantum Readiness Index and a draft Quantum-Safe Migration Handbook, and which states through its Committee of Supply 2026 position that post-quantum cryptography will be the mainstream solution for quantum-safe migration. The Monetary Authority of Singapore drives financial-sector work through an advisory that references the NIST standardisation process, joint experiments, sandbox reports and quantum funding, while the Infocomm Media Development Authority runs the National Quantum-Safe Network, launched in 2023 as Southeast Asia's first quantum-safe network infrastructure, and is consulting on draft reference specifications that combine post-quantum cryptography with quantum key distribution. All of these instruments remain advisory or in draft, so no organisation in Singapore is yet legally required to migrate.

Regulatory basis

  • CSA Quantum-Safe Handbook and Quantum Readiness Index (draft, public consultation 23 Oct to 31 Dec 2025) national Guidance
  • CSA Quantum-Safe Migration Handbook (draft for public consultation, Oct 2025) national Guidance
  • MAS Advisory on Quantum Computing and Post-Quantum Cryptography national Guidance
  • IMDA Reference Specification: Secure Deployment of Quantum Key Distribution Networks (draft for public comment) national Soft law
  • IMDA Reference Specification: Quantum Key Distribution Networks (Issue 1, draft for public comment) national Soft law

Legal status: Soft law only

No organisation in Singapore is legally required to adopt post-quantum cryptography. The CSA Quantum-Safe Handbook advises critical information infrastructure owners and government agencies to inventory cryptographic assets and plan migration to the NIST post-quantum baseline, and the MAS advisory makes the same recommendations to financial institutions, but both are advisory only and carry no enforceable obligation.

Target completion: None stated

International standards processes

  • NIST PQC standardisation process referenced by the MAS quantum advisory and followed via Post-Quantum Cryptography Coalition roadmap categories in the CSA draft migration handbook

Governmental and standards bodies

  • CSA Cyber Security Agency of Singapore, national cyber authority leading the Quantum-Safe Handbook, Quantum Readiness Index and draft Quantum-Safe Migration Handbook and the position that PQC will be the mainstream quantum-safe solution
  • MAS Monetary Authority of Singapore, financial regulator issuing the quantum advisory referencing the NIST PQC process and running sandbox experiments and quantum funding for the financial sector
  • IMDA Infocomm Media Development Authority, operating the National Quantum-Safe Network Plus and issuing draft reference specifications combining post-quantum cryptography with quantum key distribution
