Our Online Store have the new products: RFID antenna board. Currently it can work with JC10M24R and JCOP4 card chips.
Compared with normal cards, the antenna board module has a smaller size and fixed holes, which is easy to integrate in the IOT(Internet Of Things) project.

Adding PKCS#11 compatibility to smart card

Post by matteof93 » Thu Aug 01, 2019 6:07 am

Hello, I am new to the world of smart cards and Java Card ecosystem. I am still trying to figure out how the ecosystem works, anyway my target is to add PKCS#11 compatibility and support to a smart card produced by Infineon, the card supports Java Card 3.

If I understood correctly, this should be the situation:
1) the PKCS#11 library runs on the computer and it is used by software installed on the computer (for example Mozilla Firefox)
2) the communication between the computer and the card is done using APDUs, which are handled by the PC/SC standard
3) on the card there is an applet that uses Java Card APIs in order to perform operations requested by the computer

The question is: how does the communication work between the PKCS#11 library and the applet that runs on the card? I mean the software on the pc may require to sign a file, so it calls an API from PKCS#11. Then I imagine that this API should send a request for the signature to the card, how is this request generated and sent to the card? How can the card understand which operation it should perform? Can all these operations be done simply by the commands specified in the PC/SC standard?

Most importantly: can I use whatever PKCS#11 library I want (for example OpenSC) or do I have to implement a library specifically compatible with my smart card?

I have been reading documentation about PKCS#11 and Java Card for the last week and the more I read the more I get confused.

You need to knwo scp11 of GP, https://github.com/martinpaljak/GlobalP ... /docs/pdfs ,viewtopic.php?f=15&t=1692&hilit=scp11
Could you explain what SCP11 is and why I need it? Thanks

My mistake, you didn't need to know scp11.

You need to implement a library specifically compatible with my smart card. And you need to konw how the applet work in javacard.
well

Ok so I need to implement a PKCS#11 library which is able to be interfaced with the relative javacard applet. Basically the library will implement the PKCS#11 APIs and, internally, these APIs will send some kind of commands to the card, so that the applet will read the command and perform the correct crypto operation.

Am I right?
