The Ministry of Defense (MOD) will step up measures to enhance the security of telecommunication equipment in preparation for the introduction of 5G technology from 2020. It will develop a system that can detect and deactivate heat emission and other unusual symptoms if harmful components are embedded into wireless LAN and routers used in telecommunication devices. It will stem the leakage of military intelligence with an eye on a possible cyberattack by countries such as China.
The 5G technology enables the simultaneous transfer of multiple data at a higher frequency. Because of this, transmission speed also increases. The MOD plans to modernize mobile communication equipment and wireless devices that the Self-Defense Forces use for training to make them compatible with 5G. The necessary devices will be sourced from the private sector. The vulnerability to cyberattacks will rise as the volume of data transmission goes up. Thus the risk of unauthorized data access by outsiders and intelligence tapping may also increase.
To eliminate these risks, the MOD will build a system that can detect in advance harmful chips and software programs embedded in telecommunication devices and remove them. It will also use hard-to-decipher technology for encryption. It will launch R&D this autumn for the completion within fiscal 2019. (Abridged)
