SPTel, together with partnerSpeQtral, has successfully completed a Quantum Key Distribution (QKD) Proof-of-Concept sandbox with theMonetary Authority of Singapore (MAS)and major banks in Singapore to conduct hands-on testing of Quantum Key Distribution (QKD)[1] in securing electronic communications for the financial services industry. SPTel delivers quantum-safe networking solutions as part of IMDA’s, National Quantum Safe Network Plus (NQSN+) initiative, of which SPTel is the appointed operator.
The PoC covered:
Testing the use of QKD to securely transfer sensitive data over quantum-safe channels.
Collaboration across organisations and industries to deepen understanding of quantum security technologies, such as QKD.
Benefits and limitations of QKD solutions that will guide FSIs in making informed decisions on quantum-safe strategies.
Highlights of the report include:
Potential use cases of QKD in financial services
The importance of tamper-resistant and auditable trusted nodes with multi-layer security measures
Success factors to facilitate wider adoption of QKD in the financial sector which has diverse IT environments and cross-border requirements.
The report also covers the importance of strong senior management support to prioritise quantum-safe initiatives within cybersecurity and broader technology budgets as well as R&D allocations. It also highlighted the need to equip staff with technical competencies to effectively evaluate and appropriately implement the QKD solutions, both at the level of individual FI and across the broader financial services ecosystem levels, in anticipation of quantum security threats.

[1] QKD is a secure communication method for exchanging cryptographic keys only known between shared parties.
[2] In QKD, a trusted node is a physically secure node that acts as a trusted intermediary to extend QKD network connections beyond direct links by performing key management and relay functions.
