(ComputerWeekly) A group of researchers from Singtel and the National University of Singapore (NUS) has demonstrated a new technique to advance quantum key distribution (QKD) that can be used to secure communications between parties.
QKD is resistant to all types of computational hacks, including next-generation quantum computing threats. Any attempt to eavesdrop will increase the error rate of the photon sequence. This alerts the two communicating parties to an intrusion, so they can abort the session and start a new one.
“The breakthrough achieved by the NUS-Singtel Cyber Security R&D Lab not only strengthens our defences in a new cyber reality where threats are becoming more sophisticated, but it also positions Singapore as a hub for global QKD research,” said Bill Chang, CEO of Singtel’s group enterprise business.
