Dr. Pang Liang Teck’s Presentation on Quantum Computing Threats and Resilience at GovWare 2025
Dr. Pang Liang Teck, General Manager of Advanced Security Products for ST Engineering’s Cyber business, delivered a significant presentation at GovWare 2025, emphasizing the accelerating development of quantum computing and the urgent need for national-scale plans for quantum-safe security. Liang Teck highlighted that while large-scale quantum computers are not yet available, they are rapidly approaching the point where they could solve complex problems much faster than current supercomputers. This development poses a severe risk to existing encryption systems that protect sensitive information, as future quantum computers could break these cryptographic protections. Even today, attackers could collect encrypted data and wait for quantum capabilities to decrypt it later, putting future security at high risk. To address the impending threats from quantum computing, Liang Teck proposed the adoption of hybrid approaches using post-quantum cryptography (PQC) and quantum key distribution (QKD). Additionally, ST Engineering is supporting a national initiative, Singapore’s National Quantum Safe Network (NQSN), to develop and implement quantum-safe technologies at a national level for secure and critical data protection. The presentation underscored the necessity of starting the transition to quantum-safe systems now as part of a layered defense plan.
Key Points:
- Quantum computing poses a serious threat by providing the capability to solve problems that current supercomputers cannot, thereby risking current encryption methods.
- The Harvest Now, Decrypt Later (HNDL) threat underscores the risk of current quantum capabilities.
- Post-Quantum Cryptography (PQC) can be deployed through software upgrades and forms the most immediate path forward but faces adoption challenges.
- Quantum Key Distribution (QKD) uses the laws of quantum physics for secure encryption key exchange but lacks universal standards and scales differently compared to PQC.
- A hybrid approach combining PQC and QKD is essential to ensure robust quantum-safe security.
Through these measures and collaborations, ST Engineering is leading the effort to prepare for the quantum future, emphasizing the importance of starting the transition now to safeguard sensitive data.
