The RFID system based on the chaotic encryption technology is characterized in that the background computer, the control unit, the chaotic sequencer, the wireless transceiving module and the first coupling element are sequentially connected, and the second coupling element is connected with the electronic label.
Description
Technical field
the invention belongs to rfid system technical field, particularly relate to a kind of rfid system based on Chaos Encryption Technology.
Background technology
rFID is the abbreviation of Radio Frequency Identification, i.e. radio frequency identification, be commonly called as electronic tag, it is a kind of non-contact automatic identification technology from the rise of the 90's of eighties of last century, its ultimate principle is the transport property utilizing radiofrequency signal and Space Coupling (inductance and electromagnetic coupled) or radar reflection, realizes the automatic identification treating recognition object.Rfid system mainly comprises backstage computer (back end computer), radio frequency reader (read write line, Reader) and electronic tag (Tag) three part.The application process etc. of data that backstage computer primary responsibility will write Tag and read back from Tag, RFID radio frequency reader (read write line) carries out radio communication by antenna and RFID electronic tag, the reading to label data or write operation can be realized, typical radio frequency reader comprises radio receiving transmitting module (transmitter and receiver), control module and reader antenna, electronic tag is the data carrier of radio-frequency recognition system, the data being made up of RFID label antenna and label special chip are very easy to be attacked, mainly because RFID chip itself, and to be all easy in the process read and write data utilize by hacker, show according to some data of industry member, these weakness of RFID are found there is the time of one longer.Although all done improvement to a certain degree to international RFID standardization body for the privacy of RFID system and security from chip, tag manufacturer; but these improvement have obvious limitation; not be exactly the improvement of RFID system for certain frequency range for the application (the HF label that such as Texas Instruments develops band cryptoguard is applied to field of medicaments etc.) in certain class field, do not have and the perfect of essence is carried out to the security of RFID system completely.
Summary of the invention
the present invention is exactly for the problems referred to above, provides the rfid system based on Chaos Encryption Technology that a kind of security is high.
to achieve these goals, the present invention adopts following technical scheme, the present invention includes backstage computer, control module, chaos sequence generator, radio receiving transmitting module, the first coupling element, the second coupling element and electronic tag, its structural feature backstage computer, control module, chaos sequence generator, radio receiving transmitting module, the first coupling element are connected successively, and the second coupling element is connected with electronic tag.
as a kind of preferred version, the first coupling element of the present invention and the second coupling element adopt coil or microwave antenna.
as another kind of preferred version, described chaos sequence generator of the present invention comprises initial parameter values calculating section, Discrete Chaotic Map part, thresholding calculating section, chaos sequence part, initial parameter values calculating section, Discrete Chaotic Map part, chaos sequence part are connected successively, and thresholding calculating section is connected with Discrete Chaotic Map part, chaos sequence part respectively.
beneficial effect of the present invention.
the present invention proposes each electronic tag carries out data encrypting and deciphering method by unique scattered date sequence corresponding with it, the scattered date sequence produced due to Discrete Chaotic Map have pseudo-randomness, can not
predictability, to starting condition and systematic parameter extreme sensitivity, be applicable to very much doing ciphering sequence, the rfid system based on chaos encryption has higher security, has a good application prospect.
Accompanying drawing explanation
in order to make technical matters solved by the invention, technical scheme and beneficial effect clearly understand, below in conjunction with the drawings and the specific embodiments, the present invention is further elaborated.Should be appreciated that embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
