The MAS and BDF experimented with post-quantum email security as a first step in securing payment networks.
The Singapore Monetary Authority (MAS) and Banque de France (BDF) have completed an experiment with post-quantum computing (PQC) to address the “looming threat” quantum computing poses to payment networks. They looked at securing emails on Microsoft Outlook as a first step in integrating PQC into the international banking system.
The BDF and MAS exchanged digitally signed and encrypted emails using a PQC email plugin, the BDF said in a statement. The exchanges succeeded using existing internet infrastructure and post-quantum encryption standards established by the United States Department of Commerce National Institute of Standards and Technology in August.
The MAS released a technical report on the experiment. The research is timely for future-proofing the financial system, it said:
