Abstract-Smart household appliances, ranging from lightbulbs and door-locks to power switches and smoke-alarms, are rapidly emerging in the marketplace, with predictions that over 2 billion devices will be installed within the next four years. However, security implementations vary widely across these devices, while privacy implications are unclear to users. In this paper we dissect the behavior of a few household devices, specifically the Phillips Hue light-bulb, the Belkin WeMo power switch, and the Nest smoke-alarm, and highlight the ease with which security and privacy can be compromised. We then propose a new solution to protect such devices by restricting access at the network-level. Our solution does not require changes from device manufacturers, reduces burden on the end-users, and allows security to be offered as an overlay service by the ISP or from a specialist provider in the cloud.
After dissecting the behavior of three IoT devices including the Phillips Hue light-bulb, the Belkin WeMo power switch, and the Nest smoke-alarm, Notra et al. REF revealed that basic security mechanisms such as encryption, authentication, and integrity checking are absent in these devices.
