JavaCard监控文件夹
我想编写一个两种方式的应用程序：javacard 的小程序和 C# 中的应用程序。 我已经涵盖了 C#，但我想知道使用 JavaCard 是否可以监视内存上的文件夹以及我将如何做到这一点。
我有一个共享文件夹，我们称之为 temp，我想在其中存储模拟智能卡和 C# 应用程序之间的缓冲区信息。 C# 应用程序只会从该文件夹中读取并显示信息，但也会向智能卡写入请求。
例如，我模拟输入卡的 PIN 码。小程序将写入一个包含可用选项的文件，C# 应用程序将读取该文件并显示这些选项；从 C# 应用程序中，我将选择并选择并在同一文件夹中写入请求文件。此时，监视该文件夹的智能卡将读取请求并发出响应。我可以让智能卡监控该文件夹吗？
我正在考虑使用加密的 XML 文件进行请求/响应操作。但简单的 .txt 文件就很好了。
我仅限于使用JavaCard v2.2.1，并且每个操作都必须加密/解密。 （通过加密我没有问题）
I want to write a two way application: applet for javacard and an application in C#.
I've got the C# covered but i want to know if with JavaCard i can monitor a folder on the memory and how would i go about doing that.
I have a shared folder let's call it temp in which i want to store buffer information between the simulated smartcard and the C# application. The C# application will only read from that folder and display the information, but also it will write requests towards the smartcard.
For example i simulate entering the PIN for the card. The applet will write a file containing available options and the C# application will read that file and display those options; from the C# app i will chose and option and write a request file in the same folder. This is when the smartcard which is monitoring that folder will read the request and issue a response. Can i make the smartcard monitor that folder?
I was thinking of using encrypted XML files for the request/response operations. But simple .txt files are good to.
I am limited to using JavaCard v2.2.1, and every operation has to be encrypted/decrypted.
(with the ciphering i have no problem)

您无法通过 Java Card Applet 监视 Windows 文件夹，因为您想通过 .Net 应用程序进行一些监视，所以更简单的解决方案可能是
.Net应用程序定义一些专有的APDU（如获取/设置）并发送到java卡（JC）应用程序，每当JC应用程序接收到这些特定的APDU时，它就会返回一些由.Net应用程序捕获的结果。这是可行的。
You can not monitor a Windows folder via Java Card Applet, As you want to did some monitoring via .Net application,So simpler solution could be
a .Net application define some proprietary APDU (like get / set) and send to java card (JC) application , whenever JC application receive these specific APDU it will return some result which is caught by .Net application & this is feasible to.
