CODING METHOD IN GIGABIT ETHERNET-PASSIVE OPTICAL NETWORK

摘要

PURPOSE: A coding method in a gigabit ethernet-passive optical network is provided to improve the efficiency of encryption by including the exchange and manage of an encryption key into a scheduling procedure of the gigabit ethernet-passive optical network. CONSTITUTION: An optical line terminal(100) of an optical network unit(120) is registered(801,803,805). The optical line terminal(100) of optical network unit(120) is authenticated(807,809,811). The optical line terminal(100) generates a session key using an obtained public key of the optical network unit(120) in the authentication process, and the pseudo-random values. The optical line terminal(100) transmits the pseudo-random values to the optical network unit(120). The optical network unit(120), which receives the pseudo-random values, generates a session key using the received pseudo-random values and the public key of the optical line terminal(100).
