MIFARE DESFIRE EVX

[Prashanth_Baradhi]

Trying to incorporate SECTOR BASE Authentication using MIFIRE DESFire card, but as per NFC Reader Library examples, code is available pertaining to only MIFIRE PLUS card. We require a similar SECTOR BASE Authentication API for the DESFire card.

I would be grateful if anyone could point me to the source code if available.

Hello @Prashanth_Baradhi 

Thanks for contacting us and using the NXP products.

Yes, there are some examples for MIFARE DESFire EVx. But for more precisely support to you, could you share which type of reader do you use?

Hello @Prashanth_Baradhi 

Yes, good. sw672318\Examples\NfcrdlibEx10_MIFAREDESFire_EVx is helpful to you. But this example is available under an active NDA, if you've already had an NDA, please log in NFC Reader Library | NXP Semiconductors to download sw672318.

If any questions please feel free to contact us.

Hello Kelly,

Yes I have already set up the NDA and have also got the access to the specified code you are referring to but my Query is that the code specific to SECTOR based Authentication is not present in this MIFARE DESFIRE EVX program., I am looking for one similar to the one given in MIFARE PLUS , but for the MIFARE DESFIRE EVX card.

Could you please advice on this regard.

Regards

Prashanth

Hello @Prashanth_Baradhi 

Yes, I understood your mean, but please attention, memory organization of MIFARE PLUS and MIFARE DESFIRE EVx is different. The non-volatile memory of the MIFARE PLUS is organized in 32 sectors of 4 blocks (from sector 0d to 31d). Then NV-memory of MIFARE DESFIRE EVx is organized using a flexible file system. Therefore, based on the above description, the authentication process of the two is different.

Hope the above could clear up your question.
