-1. USB CCID device
-
-The USB CCID device is a USB device implementing the CCID specification, which
-lets one connect smart card readers that implement the same spec. For more
-information see the specification:
-
- Universal Serial Bus
- Device Class: Smart Card
- CCID
- Specification for
- Integrated Circuit(s) Cards Interface Devices
- Revision 1.1
- April 22rd, 2005
-
-Smartcards are used for authentication, single sign on, decryption in
-public/private schemes and digital signatures. A smartcard reader on the client
-cannot be used on a guest with simple usb passthrough since it will then not be
-available on the client, possibly locking the computer when it is "removed". On
-the other hand this device can let you use the smartcard on both the client and
-the guest machine. It is also possible to have a completely virtual smart card
-reader and smart card (i.e. not backed by a physical device) using this device.
-
-2. Building
-
-The cryptographic functions and access to the physical card is done via the
-libcacard library, whose development package must be installed prior to
-building QEMU:
-
-In redhat/fedora:
- yum install libcacard-devel
-In ubuntu:
- apt-get install libcacard-dev
-
-Configuring and building:
- ./configure --enable-smartcard && make
-
-
-3. Using ccid-card-emulated with hardware
-
-Assuming you have a working smartcard on the host with the current
-user, using libcacard, QEMU acts as another client using ccid-card-emulated:
-
- qemu -usb -device usb-ccid -device ccid-card-emulated
-
-
-4. Using ccid-card-emulated with certificates stored in files
-
-You must create the CA and card certificates. This is a one time process.
-We use NSS certificates:
-
- mkdir fake-smartcard
- cd fake-smartcard
- certutil -N -d sql:$PWD
- certutil -S -d sql:$PWD -s "CN=Fake Smart Card CA" -x -t TC,TC,TC -n fake-smartcard-ca
- certutil -S -d sql:$PWD -t ,, -s "CN=John Doe" -n id-cert -c fake-smartcard-ca
- certutil -S -d sql:$PWD -t ,, -s "CN=John Doe (signing)" --nsCertType smime -n signing-cert -c fake-smartcard-ca
- certutil -S -d sql:$PWD -t ,, -s "CN=John Doe (encryption)" --nsCertType sslClient -n encryption-cert -c fake-smartcard-ca
-
-Note: you must have exactly three certificates.
-
-You can use the emulated card type with the certificates backend:
-
- qemu -usb -device usb-ccid -device ccid-card-emulated,backend=certificates,db=sql:$PWD,cert1=id-cert,cert2=signing-cert,cert3=encryption-cert
-
-To use the certificates in the guest, export the CA certificate:
-
- certutil -L -r -d sql:$PWD -o fake-smartcard-ca.cer -n fake-smartcard-ca
-
-and import it in the guest:
-
- certutil -A -d /etc/pki/nssdb -i fake-smartcard-ca.cer -t TC,TC,TC -n fake-smartcard-ca
-
-In a Linux guest you can then use the CoolKey PKCS #11 module to access
-the card:
-
- certutil -d /etc/pki/nssdb -L -h all
-
-It will prompt you for the PIN (which is the password you assigned to the
-certificate database early on), and then show you all three certificates
-together with the manually imported CA cert:
-
- Certificate Nickname Trust Attributes
- fake-smartcard-ca CT,C,C
- John Doe:CAC ID Certificate u,u,u
- John Doe:CAC Email Signature Certificate u,u,u
- John Doe:CAC Email Encryption Certificate u,u,u
-
-If this does not happen, CoolKey is not installed or not registered with
-NSS. Registration can be done from Firefox or the command line:
-
- modutil -dbdir /etc/pki/nssdb -add "CAC Module" -libfile /usr/lib64/pkcs11/libcoolkeypk11.so
- modutil -dbdir /etc/pki/nssdb -list
-
-
-5. Using ccid-card-passthru with client side hardware
-
-on the host specify the ccid-card-passthru device with a suitable chardev:
-
- qemu -chardev socket,server=on,host=0.0.0.0,port=2001,id=ccid,wait=off \
- -usb -device usb-ccid -device ccid-card-passthru,chardev=ccid
-
-on the client run vscclient, built when you built QEMU:
-
- vscclient <qemu-host> 2001
-
-
-6. Using ccid-card-passthru with client side certificates
-
-This case is not particularly useful, but you can use it to debug
-your setup if #4 works but #5 does not.
-
-Follow instructions as per #4, except run QEMU and vscclient as follows:
-Run qemu as per #5, and run vscclient from the "fake-smartcard"
-directory as follows:
-
- qemu -chardev socket,server=on,host=0.0.0.0,port=2001,id=ccid,wait=off \
- -usb -device usb-ccid -device ccid-card-passthru,chardev=ccid
- vscclient -e "db=\"sql:$PWD\" use_hw=no soft=(,Test,CAC,,id-cert,signing-cert,encryption-cert)" <qemu-host> 2001
-
-
-7. Passthrough protocol scenario
-
-This is a typical interchange of messages when using the passthru card device.
-usb-ccid is a usb device. It defaults to an unattached usb device on startup.
-usb-ccid expects a chardev and expects the protocol defined in
-cac_card/vscard_common.h to be passed over that.
-The usb-ccid device can be in one of three modes:
- * detached
- * attached with no card
- * attached with card
-
-A typical interchange is: (the arrow shows who started each exchange, it can be client
-originated or guest originated)
-
-client event | vscclient | passthru | usb-ccid | guest event
-----------------------------------------------------------------------------------------------
- | VSC_Init | | |
- | VSC_ReaderAdd | | attach |
- | | | | sees new usb device.
-card inserted -> | | | |
- | VSC_ATR | insert | insert | see new card
- | | | |
- | VSC_APDU | VSC_APDU | | <- guest sends APDU
-client<->physical | | | |
-card APDU exchange| | | |
-client response ->| VSC_APDU | VSC_APDU | | receive APDU response
- ...
- [APDU<->APDU repeats several times]
- ...
-card removed -> | | | |
- | VSC_CardRemove | remove | remove | card removed
- ...
- [(card insert, apdu's, card remove) repeat]
- ...
-kill/quit | | | |
- vscclient | | | |
- | VSC_ReaderRemove | | detach |
- | | | | usb device removed.
-
-
-8. libcacard
-
-Both ccid-card-emulated and vscclient use libcacard as the card emulator.
-libcacard implements a completely virtual CAC (DoD standard for smart
-cards) compliant card and uses NSS to retrieve certificates and do
-any encryption. The backend can then be a real reader and card, or
-certificates stored in files.
-
-For documentation of the library see docs/libcacard.txt.
