(AjuDaily) Korea Hydro & Nuclear Power (KHNP), the state-run operator of nuclear power plants is applying a secure communications system for quantum-safe data protection developed by SK Telecom, to address concerns about hacking and security threats
SK Telecom (SKT) said that its quantum key distributor (QKD) was applied to a communications network between KHNP’s head office in Gyeongju, some 270 kilometers (167 miles) southeast of Seoul, and the KHNP office of pumped-storage hydroelectricity in Samryangjin, about 62 km away.
The commercial application of quantum cryptography communication for KHNP was the first of its kind in South Korea and was pushed to strengthen the security of power generation facilities. SKT offers specialized 5G services with ultra-low latency while addressing potential security threats with a quantum cryptographic communication solution.
The two companies have laid the foundation for smart plant construction by establishing a private 5G base to prevent the leakage of business data in power generation facilities, establishing a private IoT for the real-time transmission of data, and applying the real-time video monitoring of field conditions.
SKT said it would use advanced technologies for mobile infrastructure, QKD-based transmission technology, real-time data collection, automatic control, image analysis technology and a quantum random number cryptography generator for on-site mobile access.
