Abstract:
A system includes a medium access control (MAC) module and a precise time protocol (PTP) module. The MAC module is configured to generate an identifier for a PTP frame, generate an encrypted PTP frame by encrypting the PTP frame, and output the identifier. The PTP module is configured to receive the identifier, identify the encrypted PTP frame based on the identifier in response to the encrypted PTP frame being output from the MAC module, and time stamp the encrypted PTP frame prior to the encrypted PTP frame being transmitted.
