Telecoms equipment provider Nokia and Korean operator SK Broadband have deployed a quantum secure network for Korea Hydro and Nuclear Plant (KHNP) to protect its IT infrastructure, including data security.
Completed in August 2024, the deployment is designed to enable KHNP to protect its IP MPLS leased line network against existing and emerging cyber threats, including quantum computing-based cyberattacks.
Nokia’s Quantum-Safe Network solution uses a defence-in-depth approach with advanced network cryptography for protection against sophisticated cyber threats.
The key technologies used in the project include Nokia's transmission equipment, interconnect routers, and service access systems, as well as Nokia’s Network Services Platform (NSP).

“The integration of Nokia Quantum-Safe MACsec cryptographic technologies with KHNP’s network will significantly enhance the security and reliability of South Korea’s critical energy infrastructure," said Kim Gooyoung, Head of Enterprise Sales Division at SK Broadband.
"Advanced technologies, like quantum-safe networks, are becoming pivotal in safeguarding essential systems today and in the forthcoming quantum era.
"Collaborating with Nokia allows us to stay ahead of the constantly shifting cybersecurity environment and help our customers access the latest quantum-safe technology advancements for secure growth.”
Jay Han, Head of Network Infrastructure business at Nokia Korea, said protecting critical infrastructure is a hallmark of quantum-safe technology, and an area that Nokia understands well.
"Our industry-leading quantum-safe network solutions and proven expertise in delivering high-performance, secure technologies for critical infrastructure operators are helping companies like KHNP safeguard their essential systems to protect against disruptions and attacks caused by cyber threats," Han said.
"We look forward to working with SK Broadband to expand the use of our quantum-safe MACsec cryptographic technology throughout Korea.”
