Abstract: A tag reading system and a method using self re-encrypting protocol are provided to prevent the information exposure and position tracking by transmitting transformed messages to all inquiries of reader. A tag reading system and method using self re-encrypting protocol includes a plurality of member tags(100), a reader(111~113), a gateway(120), and a plurality of group data bases(131~139). The plurality of member tags is included in one group among groups, generates a first cryptogram re-encrypted from the identical information encrypted regarding the received inquiry, and encrypting the first cryptogram with a gateway symmetry key for the group. The reader transmits an inquiry to the member tag, receives the second cryptogram from the member tag, and outputs the received second cryptogram. The gateway generates group messages by using the second cryptogram and each gateway symmetry key corresponding to the plurality of groups. The plurality of group data bases is included in one among the plurality of groups, and obtains the identical information by encrypting the group messages into the private key of the group which includes the member tag.

Abstract: PURPOSE: A transportation pass implementing method using a MAC(Message Authentication Code) function is provided to authenticate a transportation pass using a general memory and an OTPROM(One Time Programmable ROM), thereby preventing the forgery of the transportation pass. CONSTITUTION: A transportation pass(100) includes an OTPROM(110) and a storage unit(120). The storage unit includes pass terminal data(121) and a MAC(122). The OTPROM stores an OTP value. The storage unit stores the pass terminal data and the MAC. The MAC is a result value of a MAC function calculated from the OTP value and pass terminal data. The MAC function is used for authenticating the transportation pass. The MAC is calculated from a terminal(200) and the pass terminal data is data which is stored in the terminal. The transportation pass receives the pass terminal data and MAC from the terminal and stores the pass terminal data and MAC. The terminal includes a processing unit(210) and a storing unit(220). The processing unit authenticates the transportation pass by receiving the OTP value, the pass terminal data, and the MAC from the transportation pass. [Reference numerals] (100) Transportation pass; (120,220) Storage unit; (121) Pass terminal data; (122) Message authentication code; (200) Terminal; (210) Processing unit
