Woori Technology Achieves Localization of Security Encryption Module Applicable to Nuclear Power and Offshore Wind Power

[Asia Economy Reporter Hyunseok Yoo] Woori Technology announced on the 14th that its self-developed nuclear power plant control system encryption module ‘WRALib’ has passed verification by the National Intelligence Service (NIS) and obtained the ‘Korea Cryptographic Module Validation Program (KCMVP)’ certification. The control system encryption module will be primarily applied to nuclear power plant facilities and is planned to be applied in the future to control and monitoring systems of power generation facilities such as offshore wind power.

Woori Technology is the only company in Korea to have successfully developed a control system encryption module that meets both the ‘Korean-type nuclear power plant design (ARP1400)’ standards and the ‘cybersecurity regulation’ standards. By obtaining the NIS’s KCMVP certification, it has verified excellent stability and implementation suitability.

Measures to strengthen cybersecurity for nuclear power plants have been actively promoted since 2013, marked by the Korea Institute of Nuclear Nonproliferation and Control’s establishment of the regulatory guideline ‘RS-015’. In 2016, Woori Technology led the Ministry of Trade, Industry and Energy’s project ‘Development of Cyberattack Prevention and Detection Technology for Non-Safety Grade Nuclear Power Plant Controllers’ and, together with Professor Changhoon Lee’s team from the Department of Computer Engineering at Seoul National University of Science and Technology, focused on technology development, resulting in the successful development of this nuclear power plant control system encryption module.

A Woori Technology official stated, “The encryption module verified by the NIS will be primarily applied to Woori Technology’s nuclear power plant control systems,” adding, “It will not only replace existing control systems used in domestic nuclear power plants but also be applied to Korean-type nuclear power plants exported overseas.”

He continued, “The encryption module is planned to be applied to offshore wind power following nuclear power plants,” and added, “If combined with the ‘accident and fault prediction system’ and ‘digital twin system,’ for which Woori Technology holds core technologies, the encryption module can be expanded to AI-based control monitoring systems for various power generation facilities beyond nuclear power plants and offshore wind power, indicating significant growth potential.”
