Abstract: A method for controlling a security channel for reducing system load by extending the use period of a security association key is provided. In this method, an upper bit initial value of an initialization vector of an encryption algorithm and a using range thereof are shared between a transmitting side and a receiving side when a security channel is created. Then, a secure association is created between a transmitting side and a receiving side by setting an association number, a next packet number which is a lower bit value of an initialization vector, and a secure association key. Afterward, a packet number is modified whenever a frame is transmitted until all of packet numbers are used. When all packet numbers are used, the upper bit value of the initialization vector changes.

Abstract: The invention provides a method and apparatus for allocating a dynamic band width of an EPON and an EPON master apparatus using the same. The bandwidth allocation is cycle based where every predetermined cycle, static gates are generated for all ONUs and dynamic gates are generated according to the reports using the remaining grant resource. The method for allocating an upstream bandwidth to transmit data from the ONUs to an OLT is as follows. A total allocatable grant length is calculated for the given cycle. A requested amount of grant length needed to transmit upstream data in each ONU is set based on report values collected from the report frames from all ONUs in the EPON. Then, distribution is made sequentially and repeatedly in a cycle by taking a basic unit from the total grant length and adding it to the grant length of the ONUs until the total allocatable grant length becomes 0 or the grant length allocated to all ONUs satisfy the requested amount of the grant length set in all ONUs.

Abstract: Provided is a method for setting a security channel between an OLT and at least one ONU in an EPON. In detail, a channel is generated by which the OLT makes a reciprocal security capability agreement with the ONU that wants to set a security channel in a discovery interval and then automatically registers the ONU with the security capability agreement. The security channel is set by which the OLT distributes an encryption key for the security with the ONU completed with the security capability agreement. A renewal point of the encryption key is shared by transmitting a message indicative of a time to change the encryption key between the OLT and the ONU both completed with the encryption key distribution.
