Description
Technical field
The present invention relates to the radio frequency processing technology, particularly relate to a kind of system and method that mutual dynamic anti-fake is maintained secrecy between the less radio-frequency equipment in WSN (Wireless Sensor Network) wireless sense network.
Background technology
Fake and inferior commodities flood market; Consumer's interests have seriously been damaged; Brought enormous economic loss also for simultaneously commodity production enterprise; Have very big social harm,, have very high profit margin owing to copy best brand of product (wrist-watch, case and bag, clothes, name cigarette, famous brand of wine, household electrical appliances, furniture) although enterprise and country are all taking various false proof measures that fake and inferior commodities are taken precautions against; Fraud enterprise also is that level is not poor on anti-anti-counterfeiting technology; False proof modes such as traditional anti-counterfeiting technology such as bar code, laser anti-counterfeit label, two-dimension code, the tamper of famous brand of wine machinery can be duplicated etc. because technology is simple, are difficult to play anti-fake effect truly.
Along with wireless sense network; The particularly development of RF tag and technology of Internet of things; A lot of enterprises adopt the less radio-frequency equipment of wireless sense network to carry out commodity counterfeit prevention; As it is false proof to adopt passive electronic label or limited electronic tag to carry out, and adopts the electronic tag biggest advantage to be that the coding (label signature and read write line signature) of commodity worked out by enterprise oneself, and the whole world that is coded in of every commodity has unique encoding; Can inquire about the information of commodity through network technology and to tell truth from falsehood, have very high antifalse effect.
As shown in Figure 1, comprise commodity number and label signature in the existing electronic tag identifier.The commodity number is a code name of representing commodity, and read write line can be found the information of commodity through this number.Include only the commodity number in most existing label identifier, have in the identifier of minority to comprise a label signature.
The false proof method of existing goods is on commodity, to paste antifalsification label, and antifalsification label contains the identifier of representing commodity, and read write line label reading identifier is also identified its true and false.
Prior art problems is if the fake producer has obtained the content of less radio-frequency equipment mark symbol in the wireless transmission process; As obtain the content of label identifier; And make false label with this content, because identifier contents is genuine, false label might be through the authentication of read write line; And, steal printed label or the passive RFID tags identifier is fairly simple, therefore make false label ratio and be easier to; Though steal active RFID tag identifier difficulty relatively, any radiofrequency signal all can be stolen through wireless capture technique.In case an identifier is stolen, the fake producer can use this identifier to make a plurality of false labels, and when false label came to light, false label might cause damage to commodity reputation and client's interests.
And likewise, in existing tag system, label cannot be identified the true and false of read write line.
That is to say that in the false proof authentication process of existing WSN wireless sense network, the fake producer can steal the less radio-frequency device subscription in the wireless transmission process, then sign and make false less radio-frequency equipment with this.Because signature is genuine, this type of false less radio-frequency equipment might be through the evaluation of other less radio-frequency equipment.
