Smart homes are a special use-case of the Internet-of-Things (IoT) paradigm.
Security and privacy are two prime concern in smart home networks. A
threat-prone smart home can reveal lifestyle and behavior of the occupants,
which may be a significant concern. This article shows security requirements
and threats to a smart home and focuses on a privacy-preserving security model.
We classify smart home services based on the spatial and temporal properties of
the underlying device-to-device and owner-to-cloud interaction. We present ways
to adapt existing security solutions such as distance-bounding protocols,
ISO-KE, SIGMA, TLS, Schnorr, Okamoto Identification Scheme (IS), Pedersen
commitment scheme for achieving security and privacy in a cloud-assisted home
area network.
