Description
Technical field
The present invention relates to field of intelligent cards, and more particularly, to a kind of side based on Java card downloading application program
Method and system.
Background technique
Java smart card is the smart card that can run java applet code, cannot directly store the source Java within a smart card
Code or class class file need to pass through conversion equipment before Java smart card class is imported a Java smart card device
Class file is converted to conversion applet (Converted Applet, CAP) file of standard.Existing Java card application
Program downloading, does not encrypt CAP file, it is easy to which illegally distorting because of application program causes Java card in downloading process to occur
Damage, while it being unable to satisfy the individual demand of user, service personalization degree is to be improved.
Summary of the invention
In order to which the safety and the service personalization that solve the downloading of Java card application program existing for background technique are to be improved
The technical issues of, the present invention provides a kind of method based on Java card downloading application program, which comprises
Generate the original CAP file of application program to be downloaded；
The preprocessor that operation is generated by compiler programming selects original CAP file and initializes to it；
In preprocessor, the individual demand information of original CAP file is inputted, and by the original CAP file of selection
Data and individual demand data are encrypted by symmetric encipherment algorithm, generate the application program download package of encryption；
The downloading program that operation is generated by compiler programming, the downloading to the application program download package for encryption is sent
The user of request carries out authentication；
After authentication passes through, the downloading that batch carries out application program download package, and benefit are numbered and downloaded according to JAVA card
It is decrypted with symmetric encipherment algorithm to using program download package, the data after decryption is analyzed, sentenced by verifying data
The validity of disconnected original CAP file data, the legitimacy of personalized customization demand data is analyzed and determined by data, when original
When CAP file data are effectively and personalized customization demand data is legal, downloading application program to JAVA card.
Preferably, the preprocessor is realized by Microsoft Visual C++6.0 programming.It utilizes
The included control function of VC6.0 compiler realizes that the human-computer interaction interface of preprocessor is built.Preprocessor has one
Pre-process interface.The preprocessor initially sets up newly built construction and builds overall page frame, later by select file button control
Part is drawn in frame, which realizes the function of selection original CAP file, and initializing to it by programming and limit it can only
Select the file of fixed format；Multiple dialog controls are drawn in frame later, which realizes input personalized customization
The function of demand initializes it by programming, and supports to be converted into volume to input data validation verification and by input data
Code data；Button control is drawn in frame later, which realizes pretreated function, i.e., being realized by programming will selection
CAP file data and treated that personalized customization demand data is put together, encrypted by symmetric encipherment algorithm, it is raw
At ciphertext data formed under the computer local directory that application program download package is stored in where pretreating tool.By locating in advance
Program is managed, the application program original CAP file being downloaded will be needed to be treated as encryption, comprising personalized customization demand
Application program download package.
Preferably, in preprocessor, the individual demand information of the original CAP file of input includes application program version
This number uses the time with application program limitation.
Preferably, the downloading program is realized also by Microsoft Visual C++6.0 programming.It is wanted in hardware
Aspect is sought, JAVA card is connected in computer equipment by standard card reader, and there is download tool and application in a device
Program download package.Application program download package is generated by pretreating tool.Download tool is realized by the programming of VC6.0 tool, is led to
It crosses the control function of carrying using VC6.0 compiler and realizes that the human-computer interaction interface of download tool is built.Download tool mainly has
Following interface: interface, log interface, imprint interface, wherein first interface is are downloaded in subscriber authentication interface
Level-one interface, rear three interfaces are that secondary interface can be arbitrarily switched with the presence of page clip-like state.Firstly, to guarantee user's body
Part legitimacy, download tool have subscriber authentication interface；After establishing new page framework using Page Template, pass through
VC6.0 included dialog control is drawn in frame, which realizes the function of input the user name and password, later by button
Control is drawn in frame, and the function of being verified to the user name and password is realized using programming, and verifying does not pass through download tool
It will be unable to continue to use, secondary interface entered after being verified.Secondly, being established newly for downloading interface using Page Template
After page framework, select file button control is drawn in frame, which realizes the function of selection application program download package,
The file of fixed format can only be selected by initializing to it by programming and limiting it；Multiple dialog controls are drawn to frame later
