A Radio Frequency Identification (RFID) tag and an interrogator that support a normal mode and a secure mode, and operating methods thereof are provided. The RFID tag may notify the interrogator of whether a current operating mode of the RFID tag is the normal mode or the secure mode, may perform different inventory processes based on the current operating mode, and may perform an authentication of the interrogator. Here, the RFID tag and the interrogator may also perform a mutual authentication.

Radio frequency identification (RFID) tag and interrogator for supporting normal mode and secure mode, and operation method thereof

In relation to a security function of a radio frequency identification (RFID) tag, an RFID tag and a method of updating a key of the RFID tag that may manage a key to be used for an access to a reader by storing the key in a memory having a duplex structure, thereby minimizing an update error occurring during a process of updating the key are provided.

Radio frequency identification (RFID) tag and method of updating key of RFID tag

In a radio frequency identification (RFID) security reader, by integrating an encryption module that encrypts transmission data and a decryption module that decrypts reception data from an RFID security tag to restore the reception data to original data to a modem, an input/output time period of a processor module that processes a communication protocol in an RFID security system is minimized.
