5GAA, Next-Generation Standards and System Architecture Research… Participation of Korean Institutions Required
RSU, easy physical access… “Real-time response with security control system” The activities of the 5G Automotive Association (5GAA) and the importance of infrastructure security in the development of autonomous cooperative driving were mentioned.
At the 'Autonomous Cooperative Driving Industry Development Council Technology Seminar' held at the Automotive World Korea event venue on the 12th, various presentations were made by experts on autonomous cooperative driving-related technologies and security.
As the crisis of autonomous driving grows, the importance of autonomous cooperative driving that can overcome the limitations of autonomous vehicle sensors is expected to increase.
Autonomous cooperative driving based on communication technologies such as C-V2X enables safer driving by allowing vehicles and infrastructure to share traffic information.
At the SIRIUS demonstration of Etifos’ 5G-V2X platform on the 31st of last month, Lim Ki-taek, head of the Mobility Platform Research Center at the Electronics and Telecommunications Research Institute, said, “V2X communication technology must be applied for autonomous driving at Level 4 or higher,” and “there is no other V2X technology that can transmit sensors, surrounding vehicles, and infrastructure information in real time to cars driving at high speeds.”
Automotive related The group that drives things related to 5G is 5GAA. 5GAA presents a roadmap, studies use cases and system architectures through working groups, and writes technical documents.
Hong Seung-soo, Managing Director of Etiforce, emphasized that since 5GAA also works on next-generation standards, Korea Expressway Corporation or other organizations must participate in 5GAA to prepare for the 5G era.
He continued, “Telecommunications does not exist for technology, but for services and benefits,” and added, “It is meaningful only when we can save as many lives as possible and provide comfort, but we are caught up in the debate between WAVE and 5G and are not doing anything.” He also mentioned the importance of policy.
An Ho-geun, a professional at Samsung SDS, said that while security requirements for vehicles and communication networks are well-organized, security requirements for roadside base stations (Road Side Units, RSUs) are insufficient.

From the perspective of a hacker trying to threaten the V2X system, hacking an RSU can pose a greater threat than hacking a single car, and it is likely to be a target because the physically exposed location is easy to access.
Ahn also stressed the importance of physical protection of V2X infrastructure, saying that security requirements similar to those for national critical infrastructure will be required. When the era of autonomous driving is fully realized, the V2X system will become a key national transportation infrastructure.
However, since physical access or manipulation cannot be blocked at the source, a security control system must be established to remotely monitor and respond in real time.
He said, “The basic premise of technical security is that the device is physically protected,” and “To this end, it is important to have a system that can identify and respond to threats in real time from the central control center.”
He added that the Ministry of Land, Infrastructure and Transport, road construction companies and local governments should consider establishing standard specifications for security when building systems so that companies can create products that take security into account from the design stage.
