METHOD FOR INCREASING SECURITY IN A PASSIVE OPTICAL NETWORK

摘要

It is disclosed a method for increasing security in a passive optical network. The method comprises, at an OLT: detecting an optical termination device and establishing a connection with it; generating a first PLOAM message comprising a first random number; and transmitting the first PLOAM message through the established connection. The method further comprises, at the optical termination device: receiving the first PLOAM message; calculating a first authentication code by using the first random number and a secret code stored at the optical termination device; and generating and transmitting to the OLT a second PLOAM message comprising the first authentication code. The method further comprises, at the OLT: receiving the second PLOAM message; calculating a second authentication code by using the first random number and a secret code stored at the optical line termination; and authenticating the optical termination device if the first authentication code matches the second authentication code.
