Abstract
The utility model discloses a secret key display electronic label which comprises a label body. A chip, an antenna, an encryption module, a storage module, a control module and a power source are disposed inside the label body. A display window is arranged on the label body. A display module is arranged inside the display window. The antenna, the encryption module, the storage module, the control module and the display module are respectively in electric connection with a chip. The power source is electrically connected with the display module. An authentication process is added during interaction between a reader and the electronic label, thereby preventing information of the electronic label from being obtained by an invalid reader and helping a card-holder to avoid losses caused by leakage of the information. The electronic label is provided with a display used for displaying authentication information, so that the card-holder can easily identify the invalid reader and security of the information of the electronic label is guaranteed.
Description
Technical field
The utility model belongs to information security technology and Internet of Things field, and a kind of key of specific design shows electronic tag, is used for preventing from information leakage and be replicated usurping.
Background technology
Electronic tag is a kind of communication technology, can identify specific objective and read and write related data by radio signals, and need not to set up machinery between recognition system and the specific objective or optics contacts, it is a kind of non-contacting automatic identification technology, identify destination object and obtain related data by radiofrequency signal, identification work need not manual intervention.Compared to bar code, the RFID technology has the not available waterproof of bar code, antimagnetic, high temperature resistant, long service life, read that distance is large, data can encrypt, store that data capacity is larger, the storage information change waits advantage freely on the label.
Therefore, the range of application of electronic tag is also more and more extensive.But electronic tag also has its natural defective: electronic tag has unique address, and this address information is easy to be read out, and the information of its storage inside still might and be usurped by bootlegging, causes damage to the holder.
Traditional rfid system comprises electronic tag and reader two parts at least.Electronic tag is the data carrier of radio-frequency recognition system, and electronic tag is comprised of label antenna and label special chip.RFID reader (read write line) carries out radio communication by antenna and RFID electronic tag, can realize reading or write operation tag recognition code and internal storage data.
This mode of operation responds advantage fast, easy to use so that electronic tag has had, but caused hidden danger also for simultaneously the information security of electronic tag: the information of electronic tag is passive to be read, and can't verify by reader, thereby so that being illegally accessed, the information in the electronic tag becomes possibility.
Therefore, a kind of can ensuring information security to the electronic tag that reader authenticates of research extremely has meaning.
The utility model content
The problem of mentioning in order to solve above-mentioned prior art the utility model proposes a kind of key and shows electronic tag, and this electronic tag can prevent that canned data is by bootlegging in the label.
For achieving the above object, the utility model is taked following technical scheme:
A kind of key shows electronic tag, comprise label body, label body inside is provided with chip, antenna, encrypting module, memory module, control module and power supply, label body is provided with a display window, display module is set in the display window, antenna, encrypting module, memory module, control module and display module are electrically connected with chip respectively, and power supply is electrically connected with display module.
Described memory module is ROM.
Described control module is provided with control knob.
Described display module is LED, LCD or Electronic Paper.
Principle of work of the present utility model is: reader sends communication signal and one group of random digit, electronic tag with the random digit that receives be stored in secret key encryption in the electronic tag and generate new key and be presented on the display, electronic tag sends to reader with the address information of electronic tag simultaneously, reader is searched corresponding key according to this information in terminal, the key that searches is encrypted according to identical algorithm with random digit, and the result sent to electronic tag, be presented on the display and compare, whether legal be judged as reader, thereby take the operation that continues or interrupt.Just prevented that so electronic labeling information is illegally accessed.
The beneficial effects of the utility model are: add verification process in the reciprocal process of reader and electronic tag, prevent that illegal reader from obtaining the information of electronic tag, make the holder avoid the loss that information leakage causes; Being provided with display at electronic tag and being used for showing authentication information, is that the holder recognizes illegal reader easily, has guaranteed the safety of electronic labeling information.
Description of drawings
Fig. 1 is the structural representation that the utility model key shows electronic tag.
Embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is done more clearly explanation.
Embodiment 1:
Key of the present utility model as shown in Figure 1 shows electronic tag, comprise label body 100, label body inside is provided with chip 101, antenna 102, encrypting module 103, memory module 104, control module 105 and power supply 106, memory module is ROM, control module is provided with control knob 1051, label body 100 is provided with a display window 107, the display window 107 interior display modules 108 that arrange, antenna 102, encrypting module 103, memory module 104, control module 105 and display module 108 are electrically connected with chip 101 respectively, power supply 106 is electrically connected with display module 108, and display module is Electronic Paper.
Reader sends communication signal and one group of random digit, in the electronic tag receive signal after, chip sends instruction to encrypting module, with this group random digit be stored in key k1 in the ROM and encrypt to generate show key k2 and be presented on the display, electronic tag sends to reader with the address information of electronic tag simultaneously, reader is searched key k1 according to the electronic tag address information that receives in terminal, the k1 that searches is calculated to get k2 ' with the random digit that sends according to identical cryptographic algorithm, and k2 ' sent to electronic tag, be presented on the display, relatively if k2 and the k2 ' on the display consistent, thinks that then reader is the reader through authentication, press the button of controller, communication continues, otherwise interrupt operation prevents that electronic labeling information is illegally accessed.
Embodiment 2:
The difference of present embodiment and embodiment 1 is that display module is LED.
Embodiment 3:
The difference of present embodiment and embodiment 1 is that display module is LCD.
Embodiment 4:
The difference of present embodiment and embodiment 1 is that power supply is provided with switch.
The above is preferred embodiment of the present utility model, but the utility model should not be confined to the disclosed content of this embodiment and accompanying drawing.So everyly do not break away from the equivalence of finishing under the spirit disclosed in the utility model or revise, all fall into the scope of the utility model protection.
