Welcome to ccid-emulator. The purpose of ccid-emulator is to forward a PCSC
|
|
smartcard reader as a standard USB CCID reader. If the host system is in USB
|
|
device mode, ccid-emulator forwards the local reader via USB to another
|
|
device. If in USB host mode, ccid-emulator virtually plugges in a USB CCID
|
|
reader to the host system. ccid-emulator has support for Password
|
|
Authenticated Connection Establishment (PACE) using OpenPACE
|
|
(http://sourceforge.net/projects/openpace/).
|
|
|
|
ccid-emulator is implemented using GadgetFS_. Some fragments of the source code
|
|
are based on the GadgetFS_ example and on the source code of the OpenSC_ tools.

Installation

=============

|
|
ccid as the following dependencies:
|
|
|
|
- Linux Kernel with GadgetFS_
|
|
- OpenSC_
|
|
- :ref:`npa` (only if support for PACE is enabled)

Hints on GadgetFS
|
|
-----------------
|
|
|
|
To create an USB Gadget in both USB host and USB client mode, you need to load
|
|
the kernel module :program:`gadgetfs`. A guide focused on Debian based systems to run
|
|
and compile gadgetfs, you can find `here
|
|
<http://wiki.openmoko.org/wiki/Building_Gadget_USB_Module>`_.
|
|
|
|
On OpenMoko it is likely that you need to `patch your kernel
|
|
<http://docs.openmoko.org/trac/ticket/2206>`_. If you also want to switch
|
|
multiple times between :program:`gadgetfs` and :program:`g_ether`, `another patch is needed
|
|
<http://docs.openmoko.org/trac/ticket/2240)>`_.
|
|
|
|
If you are using a more recent version of :program:`dummy_hcd` and get an error
|
|
loading the module, you maybe want to check out `this patch
|
|
<http://comments.gmane.org/gmane.linux.usb.general/47440>`_.

Hints on OpenSC
|
|
---------------
|
|
|
|
Without libnpa ccid-emulator links against libopensc, which is discouraged and
|
|
hindered since opensc>=0.12. We really need to get rid of this dependency. You
|
|
need the opensc components to be installed (especially libopensc.so). Here is
|
|
an example of how to get the standard installation of OpenSC_::
|
|
|
|
PREFIX=/tmp/install
|
|
OPENSC=opensc
|
|
svn co http://www.opensc-project.org/svn/opensc/trunk $OPENSC
|
|
cd $OPENSC
|
|
autoreconf -i
|
|
# adding PKG_CONFIG_PATH here lets OpenSC use OpenSSL with OpenPACE
|
|
./configure --prefix=$PREFIX PKG_CONFIG_PATH=$PREFIX/lib/pkgconfig
|
|
make
|
|
make install
|
|
|
|
Now :file:`libopensc.so` should be located in ``$PREFIX/lib``. Here is how to
|
|
configure ccid-emulator to use it::
|
|
|
|
./configure OPENSC_LIBS="-L$PREFIX/lib -lopensc"
|
|

|
Usage
|
|
=====
|
|
|
|
ccid-emulator has various command line options to customize the appearance on
|
|
the USB host. In order to run ccid-emulator GadgetFS_ must be loaded and
|
|
mounted. ccid-emulator is compatible with the unix driver libccid_ and the
|
|
windows smart card driver. To initialize PACE using the PC/SC API you need to
|
|
patch libccid and pcsc-lite (see directory patches).
|
|
|
|
cats-test can be used to test the PACE capabilities of a smart card reader with
|
|
PACE support (such as ccid-emulator or any other "Standardleser" CAT-S or
|
|
"Komfortleser" CAT-C) via PC/SC.
