Summary:
Because a variety of smart home devices have been deployed in today’s homes, their security against threats from the Internet is an important issue. This paper reports an analysis of communication protocols between four types of such devices, i.e., smart remote controllers for appliances, smart plugs, smart LED bulbs and network cameras. Consumers use these devices through smartphone apps or smart speakers to control their appliances remotely or on site, to condition lights, and to monitor their homes when absent. Communication between the devices and their apps is typically provided through cloud servers over the Internet, where various threats such as malwares and sophisticated attacks are observed every day. We have monitored packet traffic between about 10 or more devices of each type with corresponding servers. We found plain and encrypted HTTP and MQTT along with UDP in the captured traffic. Observed combinations of these protocols and parameters implied use of the same platforms among different types of devices.
