US Patent 9603012 Secure wireless device connection using power line messages

Technologies are generally provided to establish a secure connection between a wireless network access point and a wireless enabled device by sharing a secret key synthesized from one or more messages exchanged over power lines. Messages exchanged between devices within a location such as a household over power lines and/or with a power utility control center may be collected, for example, communication messages between a wireless enabled device and a smart meter or any other device. The wireless enabled device and a wireless network access point may synthesize a secret key from the collected messages and share the secret key to establish a secure wireless connection over a channel that is not secure.
