Danish researchers have announced a significant advancement in IT security, successfully utilizing quantum communication to transfer data between computers at Danske Bank.
The research team from the Technical University of Denmark (DTU) collaborated with Danske Bank and KPMG on this notable project, achieving a successful data transfer between two of the bank’s computers designed to simulate data centers. This event represents the first instance of data transfer in the Nordic region secured by quantum keys over a network outside of a laboratory setting.
The transfer employed a technology developed at DTU called continuous variable quantum key distribution (CV-QKD). This innovative method facilitates the creation and sharing of secure encryption keys using standard telecommunications fiber optics. As a result, it can be integrated into the bank’s network, paving the way for enhanced data security in the ongoing battle against cybercrime.
Lance McGrath, chief security officer at Danske Bank, expressed pride in supporting the researchers in achieving this milestone, emphasizing the significance of gaining first-hand experience with quantum-safe data transfer for the future of digital communication security. He stated, “As a bank, we have a responsibility to continuously seek new ways to protect our customers’ data and ensure that we stay one step ahead of criminals in the tech arms race.”
