IDENTITY AUTHENTICATION METHOD, DEVICE, AND SYSTEM FOR OPTICAL TRANSPORT NETWORK

摘要

Disclosed is an identity authentication method for an optical transport network. The method comprises: when identity authentication is started, acquiring a random number to construct an identity authentication request message, and sending the identity authentication request message to a slave side; receiving an identity authentication reply message fed back by the slave side; and parsing the identity authentication reply message, acquiring first slave side identity information, and judging whether identity authentication succeeds or not according to the first slave side identity information and saved second slave side identity information. Also disclosed are an identity authentication device and system for the optical transport network. The present invention increases security and reliability of identity authentication in the optical transport network.
