Securing a wireless mesh network via a chain of trust

Securing a wireless mesh network via a chain of trust

A master beacon device emits a data packet that is received and retransmitted by servant beacon devices in a wireless mesh network that enables the beacon devices to detect the received signal strength indicator ("RSSI") of beacon devices in proximity. Each servant beacon device transmits...

description A master beacon device emits a data packet that is received and retransmitted by servant beacon devices in a wireless mesh network that enables the beacon devices to detect the received signal strength indicator ("RSSI") of beacon devices in proximity. Each servant beacon device transmits survey data packets comprising the RSSIs and hardware identifiers of proximate beacon devices to the master beacon device, which constructs a first virtual map of the mesh network. At a later time, each servant beacon device transmits authentication data packets, which are retransmitted, each retransmitting beacon inserting an RSSI and hardware identifier of the beacon device from which the authentication data packet was received, until they reach the master beacon device, which constructs a second virtual map of the mesh network. The master beacon device compares the first virtual map to the second virtual map to determine if the network is secure.
