Solutions to strengthen the security of smart home networks with a combination of private block chain technology through three layers based on the received signal strength indicator

Internet of Things (IoT)-based smart home applications are rising in popularity. However, this trend attracts malicious activity, which causes cost-efficient security to be in high demand. This letter proposes a low-end design that reinforces the security of a home network. It uses private block chain technology and localization via RSSI-based trilateration. We investigated the benefits of private block chains over their public counterpart, and we improve the precision of the localization algorithm by testing it against different wireless technologies. The results conclude that using a private block chain with a WiFi based communication system produces the most efficient iteration of the proposed design.
