Subject: [PATCH 1/5] PIV - Improved Card Matching for Dual CAC/PIV and PIVKEY
|
||||||
|
cards.
|
||||||
|
|
||||||
|
Not all PIV applets are the same. Different versions of NIST 800-73 and improperly implemented
|
||||||
|
or not implemented required features of NIST 800-73 cases problems. Have a look at the card_issues
|
||||||
|
listed in card-piv.c. The PIV driver has tried to detect the differences based on clues found in
|
||||||
|
the ATR historical bytes and vendor version numbers for some cards.
|
||||||
|
|
||||||
|
At the same time it has tried to support the possibility there are multiple applets
|
||||||
|
on a card that the user may want to use at the same time from different applications.
|
||||||
|
This has lead to some detection problems with Dual CAC/PIV cards. The same cards
|
||||||
|
sold by the vendor may have only a PIV applet that may not be the same PIV applet that
|
||||||
|
is on the Dual PIV/CAC cards.
|
||||||
|
|
||||||
|
http://www.cac.mil/Portals/53/Documents/CAC-utilziation-and-variation-matrix-v2.03-20May2016.doc
|
||||||
|
defines a number of official CAC cards in active service. A table of the ATRs for these is now used
|
||||||
|
to detect these cards. The PIV version of the CCC is also read to see if any CAC PKI objects
|
||||||
|
are defined in the CCC, indicating it is a Dual CAC/PIV, even if the ATR is not listed.
|
||||||
|
|
||||||
|
A more conservative approach to try and handle multiple applets on a card is used. Based
|
||||||
|
on issues with the implementation of the PIV applet this may not be possible to do.
|
||||||
|
So for many cards no additional detection will be done at the start of every transaction,
|
||||||
|
and the login state can not be detected correctly.
|
||||||
|
|
||||||
|
ATRs for PIVKEY are also in the match table, as these cards have a log of issues.
|
||||||
|
|
||||||
|
Other PIV cards in the future or not yet tested may not be covered properly by this patch.
|
||||||
|
Extra debugging was added with "PIV_MATCH" to help with these other cards.
|
||||||
|
With "debug = 7;", `grep PIV_MATCH opensc-debug.log` can be used to see how a card
|
||||||
|
type and card_issues are derived.

Subject: [PATCH 2/5] PIV - Improved error handling of get_challenge
|
||||||
|
|
||||||
|
Random data from PIV card is obtained using GENERAL AUTHENTICATE command
|
||||||
|
for a request of a Challenge from the card. "00 87 00 9B 04 7C 02 81 00"
|
||||||
|
Usually 8 bytes are returned.
|
||||||
|
|
||||||
|
NIST 800-73-3_PART2, "A.1 Authentication of the PIV Card Application Administrator"
|
||||||
|
"Table 11. Authentication of PIV Card Application Administrator" shows an example of
|
||||||
|
how to do this.
|
||||||
|
|
||||||
|
Some cards (one I have: 3b:7d:96:00:00:80:31:80:65:b0:83:11:17:d6:83:00:90:00)
|
||||||
|
will not allow 2 of these commands in a row. (Maybe assuming command is only
|
||||||
|
used as in Table 11 and is expecting the second command.)
|
||||||
|
|
||||||
|
Code was added to card-piv.c so if "6A 80" is returned, try the command one more time.
|
||||||
|
For any other GENERAL AUTHENTICATE failure, SC_ERROR_NOT_SUPPORTED is returned.
|
||||||
|
piv_get_challenge may be called within a loop from sc_get_challenge if more random
|
||||||
|
data is needed thus causing the the 2 commands to sent in a row.
