Dear all, I do not know if this is the right place to ask but I think it
is the only place where the best experience with smart cards is shared.
I'm recently struggling with some issues when using smart cards for
massive signatures production where massive means a few millions
consecutive signatures for each card (what you wouldn't do to meet the
absurd customers' demand!)...
I think it is irrelevant but let me point out that this applies to cards
from two different vendors and with 2 different (USB) card readers; the
environment can handle up to 98 smart cards (yes, I changed a few
parameters in header files) but just 14 are connected. In production,
only one card type (InCard 34v2 common used in Italy) and only one
reader type are used.
To make it short, does anybody know of any predictable limit that can
cause failures (after "many" signatures the *cards disconnect*, one by
one) among the following:
- cards cannot reliably work for more than N signatures
...I know that RAM in cards should work well for N * 10^5
write operations, considering that some writing operations
may be involved when signing, that can be an issue and
would point to chip wearing?
- some counters in the PCSC / CCID code that may be
troublesome after a number of operations (honestly,
I found none but I'm not an expert here)?
- any known issue with smart card drivers, in the specific case
the proprietary InCard driver? The SW involved is
pcsc-lite, cccid, (OpenSC) pkcs11_engine for OpenSSL
and, of course, the driver itself
Did anybody try such massive use of cards?
Please help if you have any experience to share on this or point me to
some documents or forum that can be more appropriate.
Thanks
Umberto Rustichelli
