Kuala Lumpur, 1 October 2025 – On the second day of CyberDSA 2025, discussions turned towards one of the most critical challenges shaping the future of cybersecurity: the rise of quantum computing. The Cryptography Development Department of CyberSecurity Malaysia emphasized that while quantum technology promises breakthroughs in speed and capability, it also poses significant risks to existing cryptographic systems.

For sectors that rely heavily on secure and uninterrupted digital networks such as the rail industry, where operations, ticketing, and signalling depend on encrypted data exchange the emergence of quantum computing could redefine security standards. This highlights the importance of early adoption of quantum-safe strategies to safeguard critical transport infrastructure and passenger information.

To address these evolving challenges, Malaysia has taken proactive steps through its post-quantum initiatives, demonstrating a strong commitment to ensuring the nation’s digital security in the face of transformative technological change.

Malaysia’s Leadership in Building a Quantum-Ready ASEAN

A highlight of Day 2 was the Quantum Safe Migration Event, which underscored the urgency of preparing for a future where traditional encryption may no longer be sufficient. The event aimed to raise awareness of the vulnerabilities posed by quantum computing and encourage the adoption of quantum-safe solutions. By facilitating high-level discussions among ASEAN member states, the program sought to develop actionable migration plans, promote interoperability, and build cryptographic agility that can adapt to evolving threats. More importantly, it reinforced the need for regional collaboration, ensuring that ASEAN countries move together in securing their digital infrastructure against the challenges posed by quantum advancements.

Day 2 made it clear that the conversation on cybersecurity can no longer remain focused on present-day threats alone. With the inevitability of quantum computing, the urgency of preparing for post-quantum security has become a shared responsibility. Malaysia’s leadership in this space, through initiatives such as MySEAL and its regional role in the Quantum Safe Migration program, positions the country as a frontrunner in shaping a secure quantum-ready future. By aligning national efforts with global and regional collaboration, CyberSecurity Malaysia is not only safeguarding the nation’s digital resilience but also contributing to a stronger, more secure ASEAN digital ecosystem.

 Security in the Rail Industry

In the context of the rail industry, the shift toward post-quantum security holds particular significance. Modern railway systems rely heavily on interconnected digital networks for operations ranging from ticketing platforms and passenger information systems to signaling and safety controls. A breach in these systems could lead not only to service disruptions but also to risks to public safety. By adopting post-quantum cryptography, the rail industry can future-proof its digital infrastructure, ensuring that sensitive data and operational networks remain secure even in the face of quantum-enabled cyber threats. This proactive step is crucial as rail transport becomes increasingly digitized, making cybersecurity a cornerstone of reliability and public trust.

Suresh Sankaran Srinivasan, Group Head of Cyber Security & Data Privacy at Axiata, emphasized that cybersecurity is a critical priority for the rail industry, given its role as an essential component of national infrastructure. He highlighted that rail networks not only ensure safe operations but also manage sensitive customer data, including payment and transaction details. With the increasing threat of scams and cyberattacks, he stressed that robust cybersecurity measures are vital to protect personal information, build digital trust, and deliver long-term value to passengers.

Looking Ahead

As Malaysia moves towards a quantum-ready future, the implications for the rail industry are significant. With modern rail systems increasingly dependent on interconnected digital platforms, adopting post-quantum cryptography is essential to prevent data breaches, operational disruptions, and security vulnerabilities. CyberDSA 2025 serves as a vital platform for the rail ecosystem to explore emerging cybersecurity solutions, reinforcing Malaysia’s position as a regional leader in securing critical infrastructure and ensuring the resilience of future smart mobility networks.
