Singapore’s Cyber Security Agency (CSA) has set a 2031 deadline for owners of Critical Information Infrastructure (CII) systems to fully migrate to quantum-safe cryptography. This aggressive timeline reflects the nation’s proactive approach to a future threat posed by advances in quantum computing, which could undermine current digital security methods.
Organizations handling long-term sensitive data or providing essential services like communications and digital transactions are encouraged to complete their migration by 2035. CSA stated that organizations need to begin preparing for the transition, although it remains uncertain when quantum computers will become capable of breaking current methods.
This targeted approach acknowledges the heightened risk profile of CII entities and the need for accelerated migration efforts within these sectors. A grant, open from November 1, 2026, to October 31, 2027, will provide seed funding for pilot projects lasting up to six months, allowing organizations to test quantum-safe solutions in real-world scenarios. Funded pilots can be conducted internally or in collaboration with external solution providers, offering flexibility to suit varying organizational capabilities.
CSA’s guidance extends beyond CII, however, recommending that all organizations exposed to quantum-related cybersecurity risks establish a migration plan by 2027 and aim for completion by 2035. Organizations should begin assessing their risk exposure and identifying key systems requiring immediate attention, as cryptography is deeply embedded within applications, networks and infrastructure, often involving multiple technology vendors, creating a complex migration undertaking.
Organizations will need to dedicate time to identifying cryptographic dependencies, assessing associated risks and testing suitable solutions without disrupting ongoing operations. This is especially critical for legacy systems and critical infrastructure, where technology changes require careful management and validation. The CSA’s updated Quantum Readiness Index and Quantum-Safe Handbook aim to assist organizations in navigating this process, incorporating feedback from public consultation and the latest developments in quantum-safe cryptography standards.
These resources are available on the CSA website and are designed to help organizations assess their preparedness and plan their transition. Advances in quantum computing could eventually undermine widely used cryptographic methods that protect digital communications, transactions and sensitive information. Singapore’s decision to prioritize CII systems with a 2031 deadline reflects a risk-based approach, acknowledging that these entities face the most immediate and severe threats.
By preparing early, organizations can manage the transition in a planned and orderly manner, rather than reacting to an imminent crisis. The Quantum-Safe Kickstarter Grant will prioritize use cases addressing common migration challenges, including end-to-end migration of an application or system, cryptographic discovery and inventory and the migration of Operational Technology (OT), legacy, and infrastructure-heavy systems. Participants will be required to submit a report detailing their learnings and demonstrated impact, contributing to a collective understanding of best practices and potential roadblocks.
Applications will be evaluated based on project eligibility, scope, alignment with strategic goals and potential impact on Singapore’s cybersecurity ecosystem. Mrs. Josephine Teo, Minister for Digital Development and Information and Minister-in-charge of Cybersecurity and Smart Nation Group, announced these initiatives at Singapore International Cyber Week 2026, highlighting the nation’s commitment to quantum-safe security. The CSA reserves the right to prioritize applications demonstrating significant impact, signaling a commitment to supporting innovation and strengthening the nation’s overall cybersecurity posture.
