Patent ID: 8874898

Claim:
An electronic device for establishing a connection with a power line communication network comprising: a memory; a power line communication module to (i) establish a communication connection with a security server over the power line communication network and (ii) receive a network membership key encrypted with a first device encryption key from the security server; a network admission control module to (i) decrypt the encrypted network membership key using a second device encryption key stored on the memory and (ii) determine whether the encrypted network membership key was successfully decrypted; and a circuit interrupter to interrupt a circuit of the electronic device in response to the network admission control module determining that the encrypted network membership key was not successfully decrypted; wherein the power line communication module is further to receive a change device encryption key command from the security server, the change device encryption key command including an encrypted new device encryption key; and wherein the network admission control module is further to (i) decrypt the encrypted new device encryption key using the second device encryption key stored on the memory and (ii) replace the second device encryption key with the decrypted new device encryption key.
