Some time ago I tests Cardos SC_CARD_TYPE_CARDOS_M4_3, with atr:
3b:f2:18:00:02:c1:0a:31:fe:58:c8:08:74
Sign fails on final transmit of sign adpu. I analyzed adpu winscard.dll log of
SmartTrustPersonal, which CSP sign correctly.
And found that it use other way of sign throw adpu: 00 2A 80 86 ...
So I modify OpenSc, and now it sign well.
1. Add new type: SC_CARD_TYPE_CARDOS_M4_3B
2. In static struct sc_atr_table cardos_atrs[] init as:
//Old:
{ "3b:f2:18:00:02:c1:0a:31:fe:58:c8:08:74", NULL, NULL,
SC_CARD_TYPE_CARDOS_M4_3, 0, NULL },
//Modified:
{ "3b:f2:18:00:02:c1:0a:31:fe:58:c8:08:74", NULL, NULL,
SC_CARD_TYPE_CARDOS_M4_3B, 0, NULL },
/////////
3. In do_compute_signature modifies:
//Old:
sc_format_apdu(card, &apdu, SC_APDU_CASE_4, 0x2A, 0x9E, 0x9A);
//Modified:
if(card->type == SC_CARD_TYPE_CARDOS_M4_3B)
sc_format_apdu(card, &apdu, SC_APDU_CASE_4B, 0x2A, 0x80, 0x86);
else
sc_format_apdu(card, &apdu, SC_APDU_CASE_4, 0x2A, 0x9E, 0x9A);
////////
4. Add constants:
//Modified:
#define SC_APDU_CASE_4B 0x34
#define SC_APDU_B 0x20
#define SC_APDU_CASE_4B_EXT SC_APDU_CASE_4_SHORT | SC_APDU_EXT |
SC_APDU_B
/////////
5. In static size_t sc_apdu_get_length(const sc_apdu_t *apdu, unsigned int
proto) add:
//Modified:
case SC_APDU_CASE_4B_EXT:
ret += apdu->lc + (proto == SC_PROTO_T0 ? 1 : 6);
break;
/////////
6. In static int sc_apdu2bytes(sc_context_t *ctx, const sc_apdu_t *apdu,
unsigned int proto, u8 *out, size_t outlen) add:
//Modified:
case SC_APDU_CASE_4B_EXT:
if (proto == SC_PROTO_T0) {
/* again a T0 extended case 4 APDU looks just
* like a short APDU, the additional data is
* transferred using ENVELOPE and GET RESPONSE */
*p++ = (u8)apdu->lc;
memcpy(p, apdu->data, apdu->lc);
p += apdu->lc & 0xff;
} else {
*p++ = (u8)0x00;
*p++ = (u8)0x01;
*p++ = (u8)(apdu->lc >> 8);
*p++ = (u8)apdu->lc;
memcpy(p, apdu->data, apdu->lc);
p += apdu->lc;
/* only 2 bytes are use to specify the length of the
* expected data */
*p++ = (u8)(apdu->le >> 8);
*p++ = (u8)apdu->le;
}
break;
//////
7. In static void sc_detect_apdu_cse(const sc_card_t *card, sc_apdu_t *apdu):
if ((apdu->le > 256 || (apdu->lc > 255 && (apdu->flags &
SC_APDU_FLAGS_CHAINING) == 0)) &&
(card->caps & SC_CARD_CAP_APDU_EXT) != 0){
btype |= SC_APDU_EXT;
//Modified:
if(apdu->cse == SC_APDU_CASE_4B) btype |= SC_APDU_B;
/////////
}
