    摘要: Provided are a tag signal receiving apparatus that can perform digital Amplitude Shift Keying (ASK) demodulation onto signals received in a tag, decode the demodulated tag signal in synchronization, and acquire tag data in a mobile RFID reader, and a method thereof. The tag signal receiving apparatus includes: a digital demodulating block for performing ASK demodulation onto a digital tag signal received through a reader antenna and converted into a digital tag signal in an analog-to-digital (AD) converter; and a decoding block for detecting edge position information of the demodulated tag signal by performing accumulation and decoding the demodulated tag signal by using the detected edge position information. The digital demodulating block includes a channel level comparator, a phase inverter, a signal converter; and an adder. The decoding block includes an edge information detector, a correlator, and a bit data decider.

    摘要: Provided is a method for securing information between a Radio Frequency Identification (RFID) reader and tag, and an RFID Reader and tag using the same. The method includes the steps of: a) requesting an access password of the RFID tag in the RFID reader; b) extracting a key value mapped to the access password transmitted from the RFID tag and transmitting the key value to the RFID tag in the RFID reader; c) outputting a hash function value from the key value transmitted from the RFID reader in the RFID tag; and d) determining whether to allow the RFID reader to access to an RFID tag memory based on whether the outputted hash function value is the same as the access password of the RFID tag.
