Smart homes, equipped with various home automation systems, have gained popularity but also face significant cybersecurity challenges. To address these concerns, the Internet Engineering Task Force (IETF) introduced a new stan- dard, Manufacturer Usage Description (MUD), which employs a white-list ap- proach to enhance IoT security. This standard requires IoT device manufac- turers to provide MUD files specifying the allowed communication endpoints, effectively mitigating the risk of unauthorized access and distributed denial of service (DDoS) attacks. One critical aspect of ensuring the security of smart home environments lies in the authentication of plug-ins and the associated MUD files. The authen- tication process plays a pivotal role in verifying the legitimacy of the plug-ins and the communication endpoints specified within the MUD files.
