Abstract
The present invention provides a method for detecting a security module for link protection in an EPON, wherein an OLT and an ONU in the EPON can check whether or not an encryption module is present in each other and check the configuration of each other in order to avoid loss of a message when the message is encrypted for link protection between the OLT and the ONU in the EPON.
