Abstract: A power line communications (PLC) system and method for providing broadband communications over a low voltage power line are disclosed. The system and method comprise a manager that controls access to a bridge for a client where the bridge communicates with the manager to provide the client Internet access. The bridge modulates Ethernet communications from the Internet access to the low voltage power line to provide the modulated Ethernet communications to the client and the client demodulates modulated Ethernet communications from the low voltage power line to yield Ethernet communications.

Abstract: A system and method for securing communications over a low voltage power line are disclosed. At both a client and a bridge, an encrypted Ethernet communication from the low voltage power line is received. The encrypted Ethernet communication comprises a) an encryption key unique to one low voltage client and b) an Ethernet communication. Based upon the unique encryption key, the bridge decrypts the encrypted Ethernet communication to yield the Ethernet communication. At both a client and a bridge, an Ethernet communication is received. The Ethernet communication is encrypted using an encryption key that is unique to the client and sent as an encrypted Ethernet communication to the low voltage power line.
