In recent years, the Internet usage environment has been shifting from wired communications to wireless LANs. In order to connect to the Internet using a wireless LAN, it is necessary to connect to the access point. However, since wireless communication can be used by anyone who can receive its radio waves, there is a risk that the access point owner may allow unintentional connections unless measures are taken, such as setting user privileges using authentication functions such as passwords, etc. This paper focuses on the interpretation of “secret communication” and examines whether the current law can regulate such unauthorized access to a wireless LAN access point from a technical perspective.
