    摘要: A method for security in a passive optical network is disclosed. The method includes, at an optical line termination (OLT): detecting an optical termination device and establishing a connection with the device; generating a first authentication message including a first random number; and transmitting the first authentication message through the established connection. At the optical termination device, the method may include: receiving the first authentication message; calculating a first authentication code by using the first random number and a secret code stored at the device; and generating and transmitting to the OLT a second authentication message including the first authentication code. The method may further include, at the OLT: receiving the second authentication message; calculating a second authentication code by using the first random number and a secret code stored at the OLT; and authenticating the optical termination device if the first authentication code matches the second authentication code.

    摘要: A method for localizing an optical network termination (ONT) of a passive optical network is disclosed. The passive optical network comprises an optical line terminal (OLT) and an optical distribution network (ODN) having a plurality of optical links. The ONT is connectable to the OLT by a given optical link of the optical distribution network. The method includes the steps of detecting that the ONT has been connected to the OLT by an optical link of the optical distribution network; determining length information indicative of a length of the optical link; comparing the length information with a reference length information indicative of a length of the given optical link; and if the length information matches the reference length information, localizing the ONT by confirming that it is connected to the OLT by the given optical link.
