Many times we do not need to implement a more complex algorithm, but only need to know how to invoke the existing implementation. API calls, in the form of include+ functions, Java is actually nothing more than import+ class (method, variable) Form, other languages are similar, such as the front-end framework of the web, the so-called framework is actually a bunch of others have written code, you take to use, Then continue to fill in the above code, in the final analysis is actually code reuse.

I. Operation of the data　In the current Javacard development, the basic data types that can be used are byte and short, and for Java both are signed numbers, so in the basic operation there will be a lot of coercion type conversion, so often lead to data overflow situation, in order to fall into the pit, here do a brief record.A data overflow problem occurs when the data size of an integer exceeds the range that can be represented, and the program doe

Short data_length = (short) (apdu_buffer [iso7816.offset _ LC] 0xff );JavaProgramming LanguageThe integer data in is signed, that is, the highest bit determines whether it is a positive number or a negative number. However The LC domain should be interpreted as an unsigned value because it has a negative length and is meaningless. AboveCodeSection, LC bytes are in the phase of BITs and constant 0xff to convert signed bytes into unsigned values. Another aspectIn the

I finally recieved the smart-cards I'm going to use for my implementation: TheJcop21 18 KAndCosmo V7 128 K. Note that the jcop21 requires the Java card SDK 2.2.1.

Install gpshell You will need gpshell to install the applets to the javacard as apdutool pcsc support is optional (and didn't work for me ...). Go to th

The message passing model described in Figure 1 is the basis for all Java card communications.Its core is application.ProgramThe Protocol Data Unit (APDU) is a logical data packet exchanged between the CAD and Java card frameworks.The javacard framework receives any APDU commands sent by CAD and sends them to corresponding small applications.The application processes The APDU command, and then returns a response to APDU.Those APDU comply with Internat

When you start using Eclipse, you'll find the question of how to open an existing Eclipse project and start looking for a long time in the menu.

The most attractive part of eclipse is its plug-in architecture. An important concept in this system is extension points, which is the interface provided for the plug-in. Each plug-in is developed on an existing extension point, and may have its own extension point, so that the plug-in can continue development.With plug-ins, the core part of the eclipse system is easy to start: Start the basic part of the p
