KT Develops Integrated and Automated Management Solution for Quantum Cryptography Network

[Asia Economy Reporter Eunmo Koo] KT announced on the 22nd that it has completed the development of a software-defined automation solution (Q-SDN, Quantum-Software Defined Network) that can centrally monitor and control quantum encryption networks.

The Q-SDN developed by KT is characterized by its ability to centrally monitor and control quantum encryption communication networks, enabling optimal management of quantum encryption key resources and control of quantum encryption key delivery paths. This is significant as it applies the network operation automation technology and know-how accumulated by KT since 2010 to quantum encryption network control.

KT also enhanced service stability and security by applying 12 patented technologies it developed in-house, including artificial intelligence (AI) hacking detection, automatic recovery, bypass switching, and physical security technologies. It can reset quantum key routes in real-time in sections lacking quantum encryption keys or quickly identify causes when hacking occurs to perform security measures such as key deletion and bypass control of hacked sections.

In particular, Q-SDN applied the open interface standard of the Korea Information and Communications Technology Association (TTA), established by KT as a domestic unique standard, to improve compatibility between heterogeneous devices. Along with this, it also reflected the 'open layered architecture standard' completed as an ITU international standard led by KT and the European Telecommunications Standards Institute (ETSI) standard. Through this, it is expected that when quantum encryption networks expand nationwide in the future, equipment from various manufacturers can be more easily interconnected. KT plans to apply the technology developed this time to the 2021 Digital New Deal quantum encryption network pilot project.

Lee Jong-sik, Head of KT Infrastructure Research Institute (Executive Director), said, “We applied the technology and experience accumulated in network automation to quantum encryption networks to make quantum encryption communication services more convenient and secure,” adding, “We will strive not to fall behind in the development of quantum encryption communication technology being promoted mainly by major advanced countries.”
