Embodiment
Below in conjunction with most preferred embodiment shown in the accompanying drawing, be that example is further described as the application scenarios of fake certification equipment with mobile phone.
The present invention's intelligent anti-counterfeiting label as shown in Figure 1, is to connect microprocessor unit 101 and cassette plug 103 by flexible PCB 102.Microprocessor unit 101 adopts 8 chip microcontroller of built-in EEPROM, data such as the unique number of EEPROM preservation antifalsification label and password, and single-chip microcomputer uses naked brilliant unit and flexible glue nation to be encapsulated in surely on the flexible PCB 102.Cassette plug 103 is microSD plugs, and flexible PCB 102 is connected the corresponding pin of single-chip microcomputer 101 and cassette plug 103 according to microSD standard and single-chip microcomputer pinout.
Be connected to the microSD extension storage card of mobile phone when the microSD of described intelligent anti-counterfeiting label cassette plug 103 after, microprocessor unit 101 obtains power supply and starts working.Microprocessor unit 101 receive by its I/O pin and response by the initialization command that the extension storage card administrative unit of mobile phone sends, simulate a microSD storage card by handset identity with FAT16 file system.Described intelligent anti-counterfeiting label is simulated a file simultaneously as carrying out mutual media with mobile phone in the FAT16 of its simulation file system, mobile phone is to the input that will be interpreted as the intelligent anti-counterfeiting label that writes of this document, and the content that the output of intelligent anti-counterfeiting label also will be modeled as this document reads for mobile phone.
Because this document system is simulated, described intelligent anti-counterfeiting label does not need to have actual memory space with its correspondence, only need return satisfactory particular value by the reading order to key position in the program of its operation.Corresponding, the intelligent anti-counterfeiting label only need be mapped as the write command of key position writing its internal non-volatile data storage.Adopt this mode can reduce data memory space demand, reduce cost the intelligent anti-counterfeiting label.

The mode that mutual employing in the described interactive anti-counterfeit authentication method between antifalsification label 202 and the anti-counterfeit server 204 is addressed inquires to-replied, address inquires to sign indicating number and produce, comprise and adopt random number as addressing inquires to sign indicating number by described antifalsification label 202 and 204 modes of arranging in advance of described anti-counterfeit server.Crucial interactive information needs thereafter additional by addressing inquires to check code that sign indicating number and password calculate through One-way encryption algorithm as the legitimacy voucher, and verifies in mutual opposite end.For illegal request, mutual opposite end still can echo reply, and just identifying code legitimacy voucher is calculated by the password (WK) of a mistake and produces, with this further antagonism malice crack.
The critical workflow of described interactive anti-counterfeit authentication method is as follows:
1) antifalsification label 202 sends to anti-counterfeit server 204 with its unique number (ID);
2) the last hyposynchronous password (SK1) of the antifalsification label correspondence of this numbering (ID) of the local storage of anti-counterfeit server 204 inquiries, password (SK2) and One-way encryption algorithm (ENC) to be confirmed, select at random or former original inquiryed yard (C), and anti-counterfeit server 204 end passwords (SK) are set to SK1;
3) anti-counterfeit server 204 based on C and SK calculation check sign indicating number SP=ENC (C, SK), will (C SP) sends to antifalsification label 202;
4) antifalsification label 202 is based on self password (TK) and One-way encryption algorithm (ENC), and calculation check sign indicating number TP=ENC (C, TK);
5) if TP equals SP, then represent both sides' cryptosync, antifalsification label 202 calculate TP=ENC (TP, TK) and send to anti-counterfeit server 204; If TP is not equal to SP, represent that then both sides' password is asynchronous, certain wrong password (WK) of antifalsification label 202 usefulness calculate TP=ENC (TP, WK) and send to anti-counterfeit server 204; This step is carried out the ENC computing with TP as the inquiry sign indicating number of giving tacit consent to;
6) (SP SK), if SP equals TP, then confirms both sides' cryptosync to anti-counterfeit server 204 calculating SP=ENC; If SP is not equal to TP, represent that then both sides' password is asynchronous, anti-counterfeit server 204 SK are set to SK2, and repeating step 3-6.As still can not confirm in step 6 both sides' cryptosync then fake certification finish with failure; This step is carried out the ENC computing with SP as the inquiry sign indicating number of giving tacit consent to;
7) (SP SK), sends SP to antifalsification label 202 to anti-counterfeit server 204 calculating SP=ENC; This step is carried out the ENC computing with SP as the inquiry sign indicating number of giving tacit consent to;
8) antifalsification label 202 calculate TP=ENC (TP, TK), if TP equals SP, (TP TK) finishes the password update of antifalsification label then to carry out TK=ENC; This step is carried out the ENC computing with TP as the inquiry sign indicating number of giving tacit consent to;
9) antifalsification label 202 calculate TP=ENC (TP, TK) and send to anti-counterfeit server; This step is carried out the ENC computing with TP as the inquiry sign indicating number of giving tacit consent to;
10) (if SP equals TP, (SP SK) finishes anti-counterfeit server end password update to anti-counterfeit server 204 calculating SP=ENC then to carry out SK=ENC for SP, ENC (SP, SK)); So far anti-counterfeit server 204 is confirmed identity mutually and is finished password update with antifalsification label 202, and fake certification is successfully to finish; If SP is not equal to TP, then fake certification finishes with failure; This step is carried out the ENC computing with SP as the inquiry sign indicating number of giving tacit consent to;
Interactive anti-counterfeit authentication method of the present invention also can adopt the RFID label as antifalsification label, and this moment, the antifalsification label 202 among Fig. 2 no longer comprised flexible attachment components and cassette plug, but realizes mutual with mobile phone 203 by the RFID wave point.Accordingly, the program on the mobile phone 203 does not re-use the FileConnection of JSR75 programming standard yet, but adopts corresponding RFID DLL (dynamic link library).
Above-mentioned implementation procedure is a preferential implementation procedure of the present invention, and common variation and replacement that those skilled in the art carries out on basis of the present invention are included within protection scope of the present invention.
