Along with actively developing of financial IC card popularization, People's Bank of China accelerates to promote state's close algorithm financial security field and lands, and has formally issued " China's finance integrated circuit (IC) calliper model (V3.0) " (PBOC3.0).PBOC3.0 defines SM2 (asymmetric arithmetic), SM3 (hash algorithm), SM4 (symmetry algorithm) application in financial IC card security fields of China's independent development.
Financial IC card data encasement system is that financial IC card security fields individualize ingredient important in system.The original card data that this system acceptance financial IC card card management system provides, according to China Unionpay's financial IC card specification and requirement, obtain card certificate and key file by financial IC card key management system, generate the fabrication data needed for personalization system.Fabrication data are made up of multiple DGI (data packet identifier) packet meeting TLV (TAG, LENGTH, VALUE) form.Based on the needs of industry singularity and security, financial IC card data encasement system needs efficient, stable, safe generation fabrication data, is the mainstay that financial IC card individualizes system.
Due to diversity and the complicacy of fabrication data, there is multiple drawback in current traditional financial IC card data encasement system constructing fabrication data.Such as: configuration is complicated, very flexible, need the card application demand in the face of becoming increasingly complex, the application scenarios of algorithms of different IC-card and support two algorithm card is increasing, original system cannot the various fabrication data of fast creation, and numerous and diverse obscure configuration item adds the risk that keeper makes mistakes.Meanwhile, when number of cards is more, there is larger bottleneck in fabrication speed.In addition, when batch fabrication makes mistakes, because the coupling of original fabrication data processing method and formatting method is higher, log analysis has difficulties.
Summary of the invention
In order to overcome the above-mentioned shortcoming of prior art, the invention provides a kind of financial IC card fabrication data creation method, introducing the Velocity template engine based on JAVA, and add self-defining data encrypting and deciphering and formatting engine in a template.Utilize Velocity engine, financial IC card data encasement system, coupled is reduced, shields the otherness of original TAG (label) data and card algorithm.Meanwhile, by the JAVA object provided in engine template, complete the data encrypting and deciphering of algorithms of different, and the unified data exported as having standard TLV form, improve data-handling efficiency.In addition, can complete and accurate record process by the daily record of Velocity engine, for quick position fabrication corrupt data reason provides powerful guarantee.
The technical solution adopted for the present invention to solve the technical problems is: a kind of financial IC card fabrication data creation method, comprises following content:
One, the Velocity template engine master data preparatory stage:
(1) system starts and carries out initialization operation, by the application of standard debit/credit individualized template, the TAG item write into Databasce of China Unionpay's specification definition;
(2) typing algorithm template, TAG value, the algorithm that definition financial IC card is supported and standard debit/credit application type;
(3) system is to financial IC card key management system application financial IC card card certificate and key;
Two, the original fabrication data preparation stage of Velocity template engine:
(1) system imports original fabrication data file to generate;
(2) system scan resolve original fabrication data file, obtains original fabrication data content, completes the original fabrication data encasement of Velocity template engine;
Three, fabrication tasks execution phases:
(1) call the data encrypting and deciphering that Velocity template engine completes based on algorithms of different to operate;
(2) by the custom feature method of Velocity template engine, intermediate processing data is encapsulated as the normal data meeting TLV form;
(3) export the data with standard TLV form, complete the output of Velocity template engine;
(4) in conjunction with the DGI packet of China Unionpay's specification definition, target fabrication data are produced;
(5) target fabrication data file is formed according to target fabrication data layout.
Compared with prior art, good effect of the present invention is: solve the drawback that in prior art, financial IC card data encasement system exists in fabrication data generating procedure, the quick generation of fabrication data is realized by the easy configuration of Velocity template and the method for self-defined engine, the fabrication data of algorithms of different can be produced efficiently, neatly, improve the formation efficiency of financial IC card data encasement system fabrication data, elevator system operability and maintainability.Velocity technology maturation, operational efficiency is high, has complete log recording method, and in conjunction with self-defined engine, the difference of shielding algorithms of different and different types of data, can simplify the configuration of financial IC card data encasement system, improves operational efficiency, reduces maintenance cost.Concrete manifestation is as follows:
1, the financial IC card fabrication data creation method based on Velocity technology introduces Velocity engine technique.By Velocity template engine, input TAG item in the TAG item in original fabrication data, individualized template and the card certificate that obtains to financial IC card key management system and key, export the data meeting standard TLV form after encryption and decryption process.Velocity engine is as the middle layer of financial IC card data encasement system, system Primary Stage Data is prepared, analyzes original fabrication data, obtain individualized template data and request financial IC card key management system obtain data and the decoupling zero of TAG data processing and, make financial IC card data encasement system have more robustness and maintainability;
2, the financial IC card fabrication data creation method based on Velocity technology introduces self-defined engine in Velocity template.Velocity supports that introducing self-defined engine processes data, by the encipher-decipher method of self-defined engine, completes the encryption and decryption process of fabrication data.For the fabrication task of International Algorithmic, the close algorithm of state and two algorithm card, user only needs to define different algorithm templates, and does not need the processing procedure being concerned about algorithms of different in fabrication tasks carrying process completely;
3, by the providing data formatting method of engine self-defined in Velocity template, the TLV standard output of data is completed.Formatting method shields the difference of TAG data type, TLV computing method for different types of data are provided, export the TLV content of code requirement, simultaneously, for the TAG value needing special processing, formatting method provides corresponding special treatment method, only needs simple definition in a template to complete.By the providing data formatting method of self-defined engine, business processing and data layout output processing are isolated, improve maintainability and the extendability of system;
4, Velocity engine is as the key node of system, by the journal function of Velocity engine, all input TAG data of complete documentation fabrication tasks carrying and output information, for system debug and operating mistake, can quick position, reduce the development and maintenance cost of system.
