Abstract
The invention discloses an NFC tag data encryption method based on an AES128 encryption technology, which comprises the steps of acquiring identification information of an NFC tag; and performing encryption on multiple pieces of information inputted in multiple links according to the identification information of the NFC tag. The NFC tag data encryption method has the following advantages: encryption is performed by using the identification information of the NFC tag when each sector of NFC is encrypted, data stored in same areas of similar product tags is enabled to be different, and the encryption effect is improved.
Description
Technical field
The present invention relates to NFC label technical field, and in particular to a kind of NFC label data based on AES128 encryption technologies
Encryption method.
Background technology
Carrying out using NFC label during fresh agricultural products review, although NFC label with card reader communication process
In carry out mutual authentication, but the data being stored in each sector are consistent, and data are plaintexts, and bad businessman can be using reading
The data for going out carry out the batch duplicating of NFC label, cause traceability system to lose meaning, so must be encrypted to label.
In correlation technique, to the side that NFC label is encrypted it is：16 sectors of MIFARE storage cards point, each sector point 4
Block, wherein totally 64 blocks, the block 3 of each sector are control block, comprising key A, access control, key B.Wherein absolute address 0
Block deposits vendor code.Line access data can be entered separately through checking password A or password B in each sector.But correlation technique is deposited
In following problem：
If adopting similar sofware and NFC label, with regard to the data of the regular interiors of products of reproducible；
Although there is cryptoguard each sector, data are stored with plaintext version, and the data of like product are complete
Unanimously, label is made easily to replicate；
The true and false of label can not be judged rapidly.
The content of the invention
It is contemplated that at least solving one of above-mentioned technical problem.
For this purpose, it is an object of the invention to propose a kind of NFC label data ciphering method based on AES128 encryption technologies,
Lift encryption.
To achieve these goals, embodiment of the invention discloses that a kind of NFC label based on AES128 encryption technologies
Data ciphering method,
The NFC label data ciphering method based on 128 encryption technologies of AES according to embodiments of the present invention, to NFC each
Identification information when sector is encrypted using NFC label is encrypted, and deposits same area between like product label
The data of storage are different from, and lift cipher round results.
In addition, the NFC label data ciphering method based on 128 encryption technologies of AES according to the above embodiment of the present invention,
There can also be following additional technical characteristic：
Further, the identification information length of the NFC label is 4 bytes.
Further, multiple information of the plurality of link typing include：The production base information of production link typing, plus
The sales section information of the machining information, the dispensing link information of dispensing link typing and sales section typing of work link typing.
The additional aspect and advantage of the present invention will be set forth in part in the description, and partly will become from the following description
Obtain substantially, or recognized by the practice of the present invention.
Description of the drawings

It is substantially and easy to understand, wherein：
Fig. 1 is the flow chart of the NFC label data ciphering method based on AES128 encryption technologies of the embodiment of the present invention；
Fig. 2 is the NFC label data encryption process schematic diagram based on AES128 encryption technologies of one embodiment of the invention.
Specific embodiment
Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings, wherein from start to finish
Same or similar label represents same or similar element or the element with same or like function.Below with reference to attached
The embodiment of figure description is exemplary, is only used for explaining the present invention, and is not considered as limiting the invention.
In describing the invention, it is to be understood that term " first ", " second " are only used for describing purpose, and can not
It is interpreted as indicating or implies relative importance.
With reference to explained below and accompanying drawing, it will be clear that in terms of these and other of embodiments of the invention.In these descriptions
In accompanying drawing, some particular implementations in embodiments of the invention are specifically disclosed, represent the enforcement for implementing the present invention
Some modes of the principle of example, but it is to be understood that the scope of embodiments of the invention is not limited.Conversely, the present invention
Embodiment includes all changes, modification and the equivalent fallen in the range of the spirit and intension of attached claims.
Below in conjunction with the Description of Drawings present invention.
Fig. 1 is the flow process of the NFC label data ciphering method based on 128 encryption technologies of AES of one embodiment of the invention
Figure.A kind of NFC label data ciphering method based on 128 encryption technologies of AES, comprises the following steps：
S1：Obtain the identification information of NFC label.Different NFC labels has different identification informations.
In one embodiment of the invention, the identification information length of NFC label is 4 bytes.
S2：It is encrypted in multiple information of multiple link typings according to the identification information of the NFC label respectively.
In one embodiment of the invention, multiple information of multiple link typings include：The production of production link typing
The pin of base information, the machining information of processing link typing, the dispensing link information of dispensing link typing and sales section typing
Sell link information.
Specifically, based on AES128 encryption technologies NFC label data encryption process is as shown in Fig. 2 fresh agricultural products
Production base producer is believed to write production base in 0-3 sectors in NFC label using AES128 encryption technologies at production base
Breath.Process unit is using AES128 encryption technologies to write processing link information in 4-7 sectors in NFC label.Dispensing unit is used
AES128 encryption technologies are to write dispensing link information in 8-11 sectors in NFC label.Retailer uses AES128 encryption technologies pair
Write sales section information in 12-15 sectors in NFC label.When information is write due to the NFC label to fresh agricultural products use NFC
The identification information of label（I.e. 4 UID of oneself）It is encrypted so that make same area storage between like product label
Data are different from, and lift cipher round results.
In addition, other compositions of the NFC label data ciphering method based on 128 encryption technologies of AES of the embodiment of the present invention
And effect is all known for a person skilled in the art, in order to reduce redundancy, is not repeated.
