DESFire with 3KDES encryption issue

Dear Support team,

We are developing CLRC663 application with using NFC Library v05.22.00.

We have a problem with reading Mifare DESFire EV1 tag.

We issue DESFire tag with 3KDES encryption, and we use following API:

phStatus_t phalMfdf_AuthenticateISO(
                                       void * pDataParams,
                                       uint16_t wOption,
                                       uint16_t wKeyNo,
                                       uint16_t wKeyVer,
                                       uint8_t bKeyNoCard,
                                       uint8_t * pDivInput,
                                       uint8_t bDivLen
                                       )

When the program run on FRAME Command and go to the step- [Get the encrypted RndA' into bWorkBuffer], it will occur the error: [MF DF Current authentication status does not allow the requested cmd].

If wee use DES or AES encryption tag, then it will be OK.

How to fix this error? We want to know the reason why cause this error. Or there is needed parameters initialization we miss?

Hello @david13 ,

 

Actually  we provide the demo for DESFire in the extended version, you may refer to "NfcrdlibEx10_MIFAREDESFire" for details. To fetch this version, you have to sign NDA at first, then request it from the NXP doc store. Please kindly refer to the following for details.

Hi Ken,

Thanks for your reply, that help me go for next step.

I will apply for the ""NfcrdlibEx10_MIFAREDESFire"  you recommend.

Note: I didn't find "Mark Correct" button, so I will click "ACCEPT AS SOLUTION".

Plus:

Following code we wrote for 3KDES and doesn't work:
case KEY_TYPE_3KDES:
{
        Is_Gigatms_Mdf_Setkey(g_tRegisters.s2.DF.bKey ,PH_KEYSTORE_KEY_TYPE_3K3DES ,STORE_KEYNUM_3K3DES);
        status = phalMfdf_AuthenticateISO(psalMFDF, PHAL_MFDF_NO_DIVERSIFICATION, STORE_KEYNUM_3K3DES, 0, 0, NULL, 0);
        break;
}


Following DES is working:
case KEY_TYPE_DES:
        Is_Gigatms_Mdf_Setkey(g_tRegisters.s2.DF.bKey ,PH_KEYSTORE_KEY_TYPE_DES ,STORE_KEYNUM_DES);
        status = phalMfdf_AuthenticateISO(psalMFDF, PHAL_MFDF_NO_DIVERSIFICATION, STORE_KEYNUM_DES, 0, 0, NULL, 0);
        break;
}

Following code is to used to set key:
bool Is_Gigatms_Mdf_Setkey(uint8_t *pKey, uint8_t bKeyType, uint8_t bKeyName)
{
        status = phKeyStore_FormatKeyEntry(psKeyStore, bKeyName, bKeyType);

        if ((status & PH_ERR_MASK) != PH_ERR_SUCCESS)
               return FALSE;
        /* Set Key Store */
        status = phKeyStore_SetKey(psKeyStore, bKeyName, 0, bKeyType, pKey, 0);
        if ((status & PH_ERR_MASK) != PH_ERR_SUCCESS)
               return FALSE;
        return TRUE;
}

Plus,
Following is the code we write for 3KDES (this doesn't work):
case KEY_TYPE_3KDES:
{
                Is_Gigatms_Mdf_Setkey(g_tRegisters.s2.DF.bKey ,PH_KEYSTORE_KEY_TYPE_3K3DES ,STORE_KEYNUM_3K3DES);
                status = phalMfdf_AuthenticateISO(psalMFDF, PHAL_MFDF_NO_DIVERSIFICATION,                                              STORE_KEYNUM_3K3DES, 0, 0, NULL, 0);
                break;
}


But following code for DES is working:
case KEY_TYPE_DES:
{
                Is_Gigatms_Mdf_Setkey(g_tRegisters.s2.DF.bKey ,PH_KEYSTORE_KEY_TYPE_DES ,STORE_KEYNUM_DES);
                status = phalMfdf_AuthenticateISO(psalMFDF, PHAL_MFDF_NO_DIVERSIFICATION, STORE_KEYNUM_DES, 0, 0, NULL, 0);
                break;
}

Following code is to used to set key:
bool Is_Gigatms_Mdf_Setkey(uint8_t *pKey, uint8_t bKeyType, uint8_t bKeyName)
{
                status = phKeyStore_FormatKeyEntry(psKeyStore, bKeyName, bKeyType);

                if ((status & PH_ERR_MASK) != PH_ERR_SUCCESS)
return FALSE;
                /* Set Key Store */
                status = phKeyStore_SetKey(psKeyStore, bKeyName, 0, bKeyType, pKey, 0);
                if ((status & PH_ERR_MASK) != PH_ERR_SUCCESS)
                               return FALSE;
                return TRUE;
}
