Abstract:
Embodiments of the invention provide systems and methods for a cipher then segment approach in a Power Line Communication (PLC). A node or device generates frames to be transmitted to a destination node in the PLC network. A processor in the node is configured to generate a data payload comprising data to be sent to the destination node. The processor divides the data payload into two or more payload segments and encrypts the payload segments. The processor creates a frame for each of the encrypted payload segments, wherein each frame comprises a message integrity code. The processor creates a segment identifier for each frame using the message integrity code and an authentication key that is shared with the destination PLC node. The segment identifier is added to each frame.
