摘要： Provided are a method for passive radio frequency identification (RFID) security according to a security mode. An RFID tag transmits its own current security mode to a reader and the reader drives a security protocol depending on the current security mode of the RFID tag. Also, the reader grasps the ability of the tag and then the reader drive a protocol suitable for the ability through the security mode.

摘要： Provided is an apparatus for implementing an electro-optical cable distribution network in which a coaxial cable is replaced with an optical cable in order to provide a service integrating broadcast data and communication data by solving a frequency constraint problem in a cable television (CATV) network employing a conventional hybrid-fiber coaxial (HFC) network architecture. The apparatus includes an optical network unit (ONU) which converts a downstream signal received from a system operator (SO) into an optical signal and transmits the optical signal to an optical cable; and an optical cable modem which receives the optical downstream signal from the ONU and converts the received signal into an electrical signal. In addition, the ONU and the optical cable modem control signal quality of an optical path.
