Minimalistic, unfriendly user interfaces, if any; badly chosen security methods, most notably the defaults; lack of long term security; and bugs or misconfigurations are plentiful. As a result, an increasing number of owners operate unsecure devices. Our investigations into the root causes of the problems resulted in the development of Home Certificate Authority (HomeCA). HomeCAincludes a comprehensive set of secure, vendor-independent interoperable practices based on existing protocols and open standards. HomeCA avoids most of the current pitfalls in network integration by design. Long-term protocol security, permission management, and secure usage combined with simplified device integration and secure key updates on ownership acquisition pave the way toward scalable, federated IoT security.enHome Certificate Authority (HomeCA)Communications technologyInternet of Things (IoT)Network securityWireless communicationWireless Local Area Network (WLAN)Text/Conference Paper10.18420/inf2019_211617-5468
