Title:
METHOD FOR MUTUAL AUTHENTICATION BETWEEN TAG AND READER IN RADIO FREQUENCY IDENTIFICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2011/078603
Kind Code:
A3
Abstract:
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.
