The design of 1 agricultural input product traceability code
Agricultural input product traceability code is to carry the electronics mark that product identification information is presented when agricultural input product sale for user
Know code.EPC (Electronic Product Code) i.e. product electronic code, the GS1 released for international article code tissue
Global identity system a new generation coded system.Information reference effect is served as when the single item object of EPC identification, using management domain
Name, object classification are main information-recording, replacement category, lot number, the numerous complicateds attribute information such as quantity, coded format is unified,
Structure is simplified, working service facilitates, and linear parity position is avoided to distinguish, and identification read or write speed is fast.EPC coded system passes through Internet of Things
FRID identifying system interconnects, Information share and exchange with internet platform, realize to supply chain production, service, position,
The automatic accurate recognition and tracking of assets improves trade transparency, visuality and operational paradigm.
1.1 coding method
EPC is made of binary segmentation code, is had 64,96,256 three kinds of structures, can be identified single-item object number
Up to 2nThe order of magnitude.The present invention uses EPC-64II coding structure, is designed with minimal information amount cryptoprinciple, by version number
+ supply trading company (management domain name)+product category number+sequence number constitutes (totally 64), can be 4.6 × 1018The single article of part provides
Retrospect mark, much meets current demand.In view of traceability code label (usually FRID label) physical memory space is limited, remove
Meet outside enough group/cording quantities, should also compression code length as far as possible, while being deposited convenient for code read-write, processing and network system
It takes.Agricultural input product traceability code initial code is with decimal representation, and to reduce code length, 64 codes are carried out code conversion,
Length is 21 (see Fig. 1, showing traceability code coding structure) after converting.In the coding, version number is 1 bit digital N1(N1=

1.2 encryption method
Traceability code is stored in EPC inside tags, and certain hidden function can be realized to traceability code.EPC label is to outgoing
When sending plain code information, coding rule and information are easy to be monitored, crack, or even are illegally usurped, copied, distorted, and exist higher
Security risk.For the safety for ensuring traceability code, it need to be encrypted using encryption method.Encryption technology is using symmetrical, non-
It is symmetrical to wait key algorithms, traceability code is converted to the process of ciphertext in plain text.AES(Advanced Encryption Standard)
For high-performance symmetric encipherment algorithm, the algorithm speed of service is fast, high-efficient, is difficult to crack after encryption, is highly-safe.AES encryption, solution
The same key of secret emissary generates " key " using dynamic key (dynastic key) algorithm, i.e., what each encryption used
Key is all different, effectively solves the problems, such as key safety.When AES hardware encrypts, according to initial key and lead on the terminal device
Third wheel key algorithm generates each wheel dynamic key, control executes wheel number, and progress takes turns cryptographic calculation, is suitable for device memory
Of less demanding, the limited situation of computing resource.
The present invention uses software enciphering method, and ciphering process, algorithm performance are realized under conditions of not having encryption device
Height, complexity are low.Method of the invention executes cryptographic operation in user client, and remote service end runs encipheror, in this way
Encrypted object can be positioned, while convenient for realizing that the anti-fake retrospect to information of supply chain is inquired by service platform database.It should
In method, the Serial No. that initial key is domain name supervising number (domainID), timestamp (timestamp) is constituted, by servicing
End distribution and offer.Domain name supervising number is vendor number, and timestamp is the character of server-side mark Internet correct time
Sequence is accurate to ms (millisecond).Initial key has uniqueness and non-reproduction, guarantees encryption intensity and safety, is single
One article initial code generates different traceability codes, it is ensured that traceability code uniqueness reaches one one yard of anti-fake retrospect effect.For example,
Supply trading company is when to be 1011, the Internet time be 20171201036, initial key 101120171201036, to Fig. 2's
Initial code 201310020500000001272 obtains decimal system retrospect code length and is less than 78bit after encrypting, meet EPC label and deposit
It stores up capacity requirement (generally 1KB~10MB).Decryption is the inverse process of encryption, using the key authentication traceability code true and false and also originally
Beginning code.Algorithm flow is as shown in Figure 3 (showing the algorithm flow of ciphering process and decrypting process).This method passes through Java language
It realizes (complete code is shown in Table 1), algorithmic procedure is as follows：
Step1：Ciphering process
Step1-1 inputs initial code original, initial key iKey, creates AES key generator kgen, and key generates
Device generates the 128bit dynamic key sercetKey for encryption according to initial key；
Step1-2 dynamic key generates one group of expanded keys kgen, creates encrypted object cipher, and cipher uses extension
Key kgen completes group encryption operation, obtains byte encryption data；
Encryption data is converted to the traceability code of decimal representation by Step1-3.
Step2：Decrypting process
Step2-1 reads traceability code encrypted, initial key iKey, by AES key generator kgen according to initial close
Key iKey generates 128bit dynamic key sercetKey for decrypting；
Step2-2 creates cipher object by one group of expanded keys kgen of dynamic key production, and cipher is close using extending
Key executes one group of decryption oprerations, obtains the ciphertext data of bytecode form；
Decrypted result is converted into decimal code by Step2-3, is reduced to initial code.

It asks that interface and JSTRP Web Service interface establish communication interaction, inquires JSTRP database.In design of the invention, service
The emphasis and key that end remotely accesses, data parse, traceability code encodes, retrospect inquiry is system realization.
3.1 remote access
When service end system executes the business such as traceability code coding, inquiry of the domain name, product identification, supply chain retrospect, need to establish
Telecommunication, is interacted by server-side remote access interface with JSTRP platform and data exchange.With SOAP, WSDD, XML,
UDDI send based on http protocol internet access request, including test communication connection, send remote request, establish session,
Reception returns the result.
JSTRP platform provides point-to-point access by Web service interface and JSON data are transmitted.Design of the invention uses
Customized remote access interface class RemoteAccess defines overloaded method getJSONData in class, by Action layer assembly institute
It calls, realization is exchanged with JSTRP Platform communication.Step is：(1) RemoteAccess is created under webservice packet,
HttpURLConnection instance objects and access identities are created in getJSONData method, are provided according to JSTRP platform
Web service interface requests access to address URL, way of submission GET/POST, time delay for the setting of HttpURLConnection object
The characteristics such as Timeout, protocol header Type C ontent-Type, caching UseCaches, are arranged parameter by passing when client call
Enter；The tables of data and data item, including domain name, product, classification etc. of access identities instruction inquiry；(2) required parameter is appended to
URL is submitted in a manner of POST, supports HTTP.UTF-8 coding transmission, test connection JSTRP server-side；(3) pass through
GetResponseCode obtains server-side answer code, judges connection status, indicates to establish connection when answer code is 1；(4) first
When connection, the client identification of JSTRP server-side distribution is obtained by the getHeaderFields of HttpURLConnection
SessionId is stored in server of the system Cookie；(5) after successful connection, getJSONData receives JSTRP platform service end
The JSON packaged data of transmission return to Action layer assembly (EPC middleware) method and do subsequent dissection process.
The parsing of 3.2 data
Remote access interface extracts the JSON data from network transmission, cannot directly be used by application program or as view
The display data (text, number, symbol etc.) at figure interface.The target of data parsing is that it is visual that JSON data are converted to encapsulation
Change the persistence object of data.JSON data are " key/value to " object, including JSONObject object, JSONArray set,
JSONObject and JSONArray blending objects three types, Fig. 6 show JSON data format.For JSONObject,
It is right by getString (key) the method acquisition " key/value " of JSONObject when JSON is parsed, it is packaged into persistence object VO；
For JSONArray, JSON data are converted into ArrayList using JSONObject and ArrayList<VO>List；It is right
JSONObject, JSONArray blending objects need simultaneously to be converted to JSON data using JSONArray, JSONObject
HashMap<key,Vo>。
The open source library that the design uses Google to provide, using JSON data, when GSON is parsed, handled complex type data

JSON parameter, be passed to when getObjectFromJSON is called by Action layer assembly practical business method；(2)
GetObjectFromJSON analyzes JSON type, is directly converted by Gson instance method fromJson, JSON parameter type is
VO object is converted to when JSONObject, when being JSONArray or JSONObject and JSONArray mixed type, is then converted
For ArrayList<VO>；(3) EPCAction homophony method receives return data and is handled, to VO or ArrayList<VO>
Simple process is carried out using the methods of get, the data such as number, text, image is can get, is presented on view interface.Complete code
It is as follows.
3.3 traceability codes coding
User enters coded views after logging in client, and product is selected from view product list, submits coding request, clothes
Business end executes coding business, returns to final traceability code and key, EPC label is written in traceability code by reader, while being in by key
Now give client user.Implementation method is：(1) defined in Action layers of EPC middleware class EPCAction getProducts,
Tri- methods of genTraceCode and encrypt, getProducts obtain product information to be encoded and are loaded into coded views；
GenTraceCode executes initial code coding and ciphering process；Encrypt executes encipheror shown in table 1, by
The control of Struts.xml frame executes；(2) it when coded views interface is loaded into, is called first by getProducts
The getJSONData method of RemoteAccess remote access interface class obtains the JSON data of JSTRP platform passback, passes through
GetObjectFromJSON analytic method is converted to ArrayList<productVo>List returns to the side getProducts
Method；(3) getProducts analyzes ArrayList<productVo>Data extract productVo object, pass through
ProductVo.getXXX method reads the information such as supplier, the name of an article, classification, specification, batch number, is presented on view interface；(4)
When selecting appointed product in coded views, submitting coding request, genTraceCode receives incoming productVo object, mentions
Domain name, the classification in productVo are taken, getJSONData remote inquiry is passed through and obtains vendor code, classification code and batch
It number is encoded, generates initial code original；(5) initial code original is added when genTraceCode calls encrypt
It is close, traceability code is generated, label is written by client serial ports.
3.4 retrospect inquiries
Two product identification inquiry, supply chain retrospect selections are provided when client retrospect inquiry, server-side is according to client
The label traceability code of incoming reader recognition controls class by EPCAction to realize traceability code decryption, remote access inquiry, number
According to dissection process process.Implementing step is：(1) query method and decrypt method are defined in EPCAction class,
Check is main prosecutor method, for receiving request, controlling each layer assembly method call, executes retrospect query function；Decrypt quilt
Query method is called, and for decrypting traceability code, decrypt uses 1 decipherment algorithm of table, restores initial code original；(2)
Original data return to query, and query analysis data simultaneously extract supply trading company, three classification number, sequence number fragment codes
As querying condition, access interface getJSONData method remote inquiry domain name, classification, batch number information are called, obtains JSON
Data；(3) JSON data are resolved to productVo object using the getObjectFromJSON method in 3.3 sections by query；
(4) checkTrace operational approach is created in Biz layers, and productVo parameter is received when checkTrace is called by query,
Domain name domain, classification catagory, batch number batch are obtained using get method, and converts productVo according to selection
For JSON formatted data, { " domain " is converted to when selecting product identification inquiry:domain,"catagory":
catagory,"batch":Batch }, when selecting supply chain retrospect, using current supplier's domain name supplier as key value, turn
It is changed to { " supplier ":[domain,catagory,batch]}；(5) JSTRP platform data is accessed by getJSONData
File data is managed in library, inquiry, obtains JSON data, and JSON encapsulates supply node product information in traceability chain, by
CheckTrace calls getObjectFromJSON to be parsed and is converted to retrospect inquiry visualized data, is presented to the user.
