An Overview of Wireless IoT Protocol Security in the Smart Home Domain
This work addresses security deficiencies in IoT protocols for smart home consumers, but it is incremental as it offers a comparative overview without introducing new methods.
The paper provides an overview of wireless IoT protocols like KNX-RF, EnOcean, Zigbee, Z-Wave, and Thread in the smart home domain, analyzing their security features and comparing them to advise on more secure options.
While the application of IoT in smart technologies becomes more and more proliferated, the pandemonium of its protocols becomes increasingly confusing. More seriously, severe security deficiencies of these protocols become evident, as time-to- market is a key factor, which satisfaction comes at the price of a less thorough security design and testing. This applies especially to the smart home domain, where the consumer-driven market demands quick and cheap solutions. This paper presents an overview of IoT application domains and discusses the most important wireless IoT protocols for smart home, which are KNX-RF, EnOcean, Zigbee, Z-Wave and Thread. Finally, it describes the security features of said protocols and compares them with each other, giving advice on whose protocols are more suitable for a secure smart home.
