The development of the Internet of Things (IoT) has made extraordinary
progress in recent years in both academic and industrial fields. There are
quite a few smart home systems that have been developed by major
companies to achieve home automation. However, the nature of smart
homes inevitably raises security and privacy concerns. In this paper, we
propose an improved energy-efficient, secure, and privacy-preserving
communication protocol for the smart home systems. In our proposed
scheme, data transmissions within the smart home system are secured by
a symmetric encryption scheme with secret keys being generated by
chaotic systems. Meanwhile, we incorporate Message Authentication
Codes (MAC) to our scheme to guarantee data integrity and authenticity.
We also provide detailed security analysis and performance evaluation in
comparison with our previous work in terms of computational complexity,
memory cost, and communication overhead.
