如何使用RFID读卡器（javax.smartcardio）识别德国身份证？

Question

Hello Twogether,

I am writing a Java-Application using the

javax.smartcardio.*;

The uid (32 bit) of german id card is generated randomly at each access. The atr (152 bit) stays the same.

Currently I take the uid of rfid cards and if it is a german id card the atr.

Is there a way to get more informations from Smartcards using smartcardio?

How can I improve the german id card identification?

Thanks in Advance

Answer 1

The ID of German ID card is unique and unchanged for every card. To access this unique ID (which is stored in a file), you have to establish File-Read keys after mutual authentication. The temporary ID is used as a card challenge for key derivation functions. I am sure IAS ECC v1 will help you.
