The fields to which IoT applies are widely found in domestic, industrial, national, and other facilities, where it serves various functions depending on the environment. However, most IoT systems communicate with servers and control IoT devices to function according to the server's requests and in this process, there is the threat of an IoT attack. Studies on security such as authentication systems as communication security techniques are undertaken to cope with it. However, systems with limited resources, such as IoT, require overhead to perform encryption operations for authentication. To solve this problem, the mechanism proposed in this paper performs authentication through subchannels and injects specific patterns into time stamps and time intervals to authenticate them. The mechanism does not use additional authentication solutions in limited hardware resource environments and performs authentication with physical timers and interval operations inside the system.
