1. A device for communicating data over a power line, the device comprising:
- a first modem communicatively coupled to the power line; and
a second modem communicatively coupled to the power line and said first modem, wherein said first modem is configured to decrypt data received from the power line using a first encryption key and to communicate the data decrypted with the first encryption key to said second modem, and wherein said second modem is configured to decrypt data received from the power line using a second encryption key and to communicate the data decrypted with the second encryption key to said first modem.

Abstract
The repeater of the present invention communicates data signals over power lines. The repeater of one embodiment includes at least one modem that receives a data packet and attempts to decrypt the data packet with a first and/or second encryption key. If the packet is successfully decrypted using the first encryption key, the packet is encrypted using the second encryption and transmitted over the power line. If the packet is successfully decrypted using the second encryption key, the packet is encrypted using the first encryption and transmitted over the power line.
