Description
Technical field
The present invention relates to radio frequency processing technology, particularly relate to a kind of at WSN(Wireless Sensor Network) the secret system and method for dynamic anti-fake mutually between less radio-frequency equipment in wireless sense network.
Background technology
Fake and inferior commodities flood market, consumer's interests have seriously been damaged, the enterprise of Ye Gei commodity production has simultaneously brought huge economic loss, there is very large social harm, although enterprise and country are all taking various false proof measures to take precautions against fake and inferior commodities, but owing to copying best brand of product (wrist-watch, case and bag, clothes, name cigarette, famous brand of wine, household electrical appliances, furniture) there is very high profit margin, fraud enterprise is also that level is not poor in anti-anti-counterfeiting technology, traditional anti-counterfeiting technology is as bar code, laser anti-counterfeit label, Quick Response Code, the false proof modes such as famous brand of wine machinery tamper are because technology is simple, can copy etc., be difficult to play anti-fake effect truly.
Along with wireless sense network, the particularly development of radio-frequency (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 adopt passive electronic label or limited electronic tag to carry out false proof, adopt the advantage of electronic tag maximum to be that coding (label signature and read write line signature) the Shi You enterprise oneself of commodity works out, the whole world that is coded in of every commodity has unique coding, by network technology, can the information of commodity be inquired about and be told truth from falsehood, there is very high antifalse effect.
As shown in Figure 1, existing electronic tag identifier comprises commodity number and label signature.Commodity number is the code name that represents commodity, and read write line can be found the information of commodity by this number.In most existing label identifier, only include commodity number, have 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 that represents commodity, and read write line label reading identifier is also identified its true and false.
The problem of prior art is if fake producer has obtained the content of the identifier of less radio-frequency equipment in wireless transmission process, as obtain the content of label identifier, and manufacture false label by this content, because identifier contents is genuine, false label likely can be by the authentication of read write line; And, steal printed label or passive RFID tags identifier is fairly simple, therefore manufacture false label ratio and be easier to; Although steal active RFID tag identifier difficulty relatively, any radiofrequency signal all can be stolen by wireless capture technique.Once an identifier is stolen, fake producer can manufacture a plurality of false labels with this identifier, and when false label is found, false label likely causes damage to commodity reputation and the benefit of client.
And similarly, in existing tag system, label cannot be identified the true and false of read write line.
That is to say, in the false proof authentication process of existing WSN wireless sense network, fake producer can steal less radio-frequency device subscription in wireless transmission process, with this, signs and makes false less radio-frequency equipment.Because signature is genuine, this type of false less radio-frequency equipment likely can pass through the evaluation of other less radio-frequency equipment.
