摘要： A relaying method of an optical signal of a hybrid relaying apparatus in a gigabit passive optical element includes: selecting and receiving any one of a first serial electrical signal corresponding to a downlink wavelength division multiplexing-passive optical line terminal (WDM-PON OLT) optical signal and a second serial electrical signal corresponding to a downlink gigabit passive optical network optical line terminal (GPON OLT) optical signal; modulating the downlink serial electrical signal to a downlink GPON transmission convergence (GTC) frame; extracting control information for uplink transmission from the downlink GTC frame; converting the downlink GTC frame into the downlink serial electrical signal; and converting the converted serial electrical signal into an optical signal and transmitting the converted optical signal in a GPON OLT optical transceiver.

摘要： 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.

摘要： A high-speed Galois Counter Mode-Advanced Encryption Standard (GCM-AES) block cipher apparatus and method is provided. The apparatus can operate at a low clock frequency of 125 MHz and provide a 2 Gbps link encryption function in an Optical Line Termination (OLT) and an Optical Network Unit (ONU) of an Ethernet Passive Optical Network (EPON). 11-round block cipher of 128- bit input data is implemented using an 8-round Counter-AES (CTR-AES) block cipher module and a 3-round CTR-AES block cipher module, so that it is possible to provide a 1 Gbps link security function for an input frequency of 62.5 MHz and a 2 Gbps link security function for an input frequency of 125 MHz.

摘要： An apparatus and method for providing a security function of frames transmitted between optical network terminals (OLTs) and optical network units (ONUs) in an Ethernet passive optical network (EPON) providing media access control (MAC) services are provided. The apparatus includes: a frame classifier distinguishing the type of a frame, and based on the logical link identifier (LLID) of the distinguished frame, determining whether or not the frame is a security link to which a security function is to be applied; a bypass unit delaying a no-security-function frame so that a processing time for converting the security-function-applied frame classified in the frame classifier into an encrypted frame is the same as a time for processing the no-security-function frame; and a parameter generation unit transmitting in relation to each of the LLIDs, a parameter set value including a security-function-application setting signal used in the encryption, decryption and authentication of the frame, a frame decryption signal, an encryption mode selection signal, and an authentication intensity adjustment signal.

摘要： The present invention discloses methods for manufacturing a metal line of a semiconductor device that can prevent undesirable etching of an edge of an interlayer insulating film. In accordance with the method, a lower metal line exposed by a via contact hole is covered by a photoresist film pattern which is formed via an exposure and development process using an upper metal line mask. An etching process is performed using the photoresist film pattern as a mask to form the upper metal line region that is then filled to form an upper metal line after removing the photoresist film pattern.
