A team of researchers from Oak Ridge National Laboratory, Ohio State University, and Duke University has successfully developed a system that relays quantum encryption five to ten times faster than present methods, offering a secure solution to key exchange problem --  a method in cryptography.

The researchers applied quantum key distribution that designs and distributes encryption codes in megabit-per-second rates. They claimed that if cybersecurity measures before were inadequate with breaches and hacks, the new system will improve the future of cybersecurity.

In the principle of quantum cryptography, it allows one to encrypt a message in a way that is not easily read by just anyone and if correctly built, no hacker can easily hack a system. The QKD that researchers built is a group of encryption keys sent individually from the encrypted message. It also allows the information to be hack-proof.

Research member Nurul Taimur Islam from Duke University said: “We wanted to identify every experimental flaw in the system, and include these flaws in the theory so that we could ensure our system is secure and there is no potential side-channel attack.”

The team explains that if the message or the encryption keys tamper, it would alert both the sender and the receiver.

The research has been published in the peer-reviewed multidisciplinary open-access journal, Science Advances.
