ABSTRACT:
A method of data communication between power line communication (PLC) stations belonging to different PLC cells includes transmitting a station ID of a PLC reception station to a PLC cell bridge (CB) of a first PLC cell to which a PLC transmission station belongs, receiving a group identification (GID) and an encryption key of a second PLC cell to which the PLC reception station belongs from the PLC CB of the first PLC cell, encrypting data to be transmitted using the encryption key of the second PLC cell, and transmitting the station ID of the PLC reception station, the GID of the second PLC cell, and the encrypted data, to the PLC CB of the first PLC cell, and an apparatus to perform the method.
