Patent ID: 7529372

Claim:
A method for adding a remote device to a logical network on a network medium, the method comprising: transmitting a first broadcast message over the network medium, the first broadcast message having a first Set Network Encryption Key (SetNEK) request with a unique, temporary network encryption key (NEK) and being encrypted with a device encryption key (DEK) of the remote device; transmitting a second broadcast message over the network medium, the second broadcast message requiring a first response from the remote device and being encrypted with the unique, temporary NEK; determining a media access control (MAC) address of the remote device by receiving the first response and extracting the MAC address; transmitting a second SetNEK request with a local NEK for the logical network to the remote device; transmitting a unicast message directly to the remote device using the MAC address, the unicast message requiring a second response from the remote device and being encrypted with the local NEK; and confirming that the remote device has been added to the logical network based on receipt of the second response; wherein the network is a powerline network.
