Abstract
A system and a method for providing a secured transmission through an authenticated encryption for each ONU in downlink transmission of an OLT in GPON are provided. The GPON system includes an OLT for generating a GTC downlink frame by receiving data from an external service provider and ONUs for receiving the GTC downlink frame from the OLT and processing the received GTC downlink frame. The OLT performs the authenticated encryption for the generated GTC downlink frame according to the ONU by including an authentication generator and the ONU determines whether the GTC downlink frame is allowed to be processed or not by checking the authentication of the received GTC downlink frame through an authentication checker.
