| ETRI, Hyundai Motor Company, Kakao, SKT, etc. have pre-adopted four international standards, including ▲V2X communication environment security guidelines ▲Connected car security threat definition ▲Quantum noise random number generator structure ▲Smart metering service security guidelines.

Korean companies and organizations participated in establishing international standards for information security in the era of the Fourth Industrial Revolution, making their voices heard.

The National Radio Research Agency of the Ministry of Science and ICT announced that four recommendations on intelligent vehicle security, quantum cryptography, and smart grid, developed by Korea, were pre-adopted as international standards at the International Telecommunication Union Telecommunication Standardization Sector (ITU-T) SG17 (Security) international conference held in Geneva, Switzerland from August 27 to September 5.

The first recommendation, the international standard 'V2X Communication Environment Security Guidelines (X.1372)', defines security technology for vehicle communication, which is the most fundamental for autonomous vehicle services.

This standard has been developed since 2014 by the Electronics and Telecommunications Research Institute (ETRI), Hyundai Motor Company, and Kakao Mobility. V2X (Vehicle-to-Everything) communication refers to communication between vehicles (Vehicle to Vehicle; V2V), vehicles and transportation infrastructure (Vehicle to Infrastructure; V2I), vehicles and mobile devices (Vehicle to Device; V2D), and vehicles and pedestrians (Vehicle to Pedestrian; V2P).

By defining security threats, security requirements, and use cases for each communication channel, this document is expected to serve as useful data for domestic industries researching autonomous vehicles, helping them develop products, prevent duplicate investments, and ensure vehicle safety.

The second recommendation, the international standard 'Connected Car Security Threat Definition (X.1371)', defines use cases for providing intelligent vehicle security services and identifies and defines security threats that may arise in each case.

This standard, developed by ETRI, Hyundai Motor Company, and Kakao Mobility since 2018, identifies and defines security threats that consider external hacking, backend servers, communication channels, and update procedures for intelligent vehicle security.

It is expected to be applied as a basic standard to the international standard for intelligent vehicle security developed by ITU-T in the future, and it is also expected to be utilized in domestic vehicle security research, securing technological superiority and contributing to exports.

The third recommendation, 'Quantum Noise Random Number Generator Structure (X.1702)’ The international standard defines the world's first random number generation method that applies quantum technology from a security perspective.

This standard, which has been developed by SKT since 2018, is a quantum technology that generates unpredictable and patternless pure random numbers, and is expected to enhance the security of cutting-edge services such as the Internet of Things, autonomous vehicles, and smart cities.

The fourth recommendation, the international standard 'Smart Metering Service Security Guidelines (X.1332)', defines security measures to safely utilize data collected from users' smart meters in a smart grid environment.

Smart grid is a service that manages the effective supply of electricity by remotely automating the transmission of electricity usage and quality information from electricity suppliers to all electricity consumers.

This standard, developed under the leadership of the National Security Research Institute since 2016, defines how electricity usage and quality information collected from smart meters installed in consumer areas can be safely shared among power companies, value-added service providers, and consumers. Therefore, it is expected to be applied to the shared use of electric power and energy big data, which is expanding through the domestic new energy industry plan.

Meanwhile, at this meeting, our country proposed and passed four new standardization tasks, including the 'Definition of Distributed Ledger Technology Terminology' standard, which is the result of the recently concluded FG-DLT (ITU-T Focus Group on Application of Distributed Ledger Technology) meeting. It is expected that Korea's standardization position will further expand in the future research and development of security technologies, including blockchain technology.

Lee Kyung-hee, head of the International Cooperation Team at the National Radio Research Agency, said, “Based on the results of this international conference, we have confirmed Korea’s status in the field of information security within the ITU-T,” and “We expect this to greatly contribute to enhancing the international market competitiveness of the domestic information security industry.”
