Power line based theft protection of electronic devices

摘要

Technologies for establishing and managing a connection with a power line communication network include establishing a communication connection between an electronic device and a security server. A default device encryption key associated with the electronic device is changed to correspond with a new device encryption key of the security server. Thereafter, the electronic device may only join a power line communication network of a particular security server using a network membership key, which is encrypted with the device encryption key that the particular security server associates to the electronic device. The electronic device contains a circuit interrupt to interrupt a circuit of the electronic device if the electronic device is not able to successfully decrypt the network membership key.

主权项

1. 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.
