摘要： A method for mutual authentication between a tag and a reader includes operations (a) through (f).　 In operation (a), tag information including a unique identification EPC_ T , a first encryption key, and a second encryption key is stored by the tag and the reader. In operation (b), a reader random number N_ R is generated and transmitted to the tag by the reader. In operation (c), a tag response RESP_ T is generated by using a CRC calculation function and transmitted to the tag response RESP_ T to the reader by the tag receiving the reader random number N_ R . In operation (d), the tag response RESP_ T is verified by using the CRC calculation function, and a reader response RESP_ R to a result of the verification is generated and transmitted to the tag by the reader. In operation (e), the reader response RESP_ R to the result of the verification received from the reader is verified by using the CRC calculation function and the first encryption key and the second encryption key are updated by the tag. In operation (f), the first encryption key and the second encryption key are updated by the reader.
