Smart Internet of Things (“IoT”) web of trust

This invention describes a system to secure networks of smart devices (IoT). It works by having a central control unit, called a network gateway, constantly watch the communication patterns of devices already deemed trustworthy. If a trusted device starts acting strangely, the gateway can isolate it, either by cutting off its communication with other trusted devices or by forcing its messages through a monitored channel, all while keeping track of when that device first joined the trusted network.
