During the 2011 Great East Japan Earthquake, numerous medical facilities were destroyed and data servers containing years of patient records were washed away by the tsunami. Since then, Japanese medical professionals have recognized the importance of having remotely located, secret and secure data backup systems as contingency plans.

So much so, a group of researchers from The National Institute of Information and Communications Technology (NICT) and Kochi Health Science Center (KHSC) of Japan have now successfully created a data backup system which connects servers within an 800-kilometer network with a satellite link that transmits or retrieves data in nine seconds.

Known as H-LINCOS‘ the system is not only implemented with authentication functions but also quantum-safe public-key cryptography, to ensure its safety under next generation quantum computing attacks.

Researchers demonstrated H-LINCOS’ capability to recover important medical information such as prescription records and allergy information and have them displayed on screens for an average of 15 seconds. They are now planning to experiment the reliability and performance of H-LINCOS with increased storage size and numbers of connected terminals.
