How to detect DESFire EV1 vs EV2 vs DESFire (MF3ICD40)

Hello guys,

I am trying to determine the class of a bunch of MIFARE DESFire cards, to be able to tell DESFire (MF3ICD40) from DESFire EV1, and EV1 from EV2.

Running `hf search` on the one I currently have handy returns the following:

pm3 --> hf search

 ATS : 06 75 77 81 02 80 02 F0           
       -  TL : length is 6 bytes          
       -  T0 : TA1 is present, TB1 is present, TC1 is present, FSCI is 5 (FSC = 64)          
       - TA1 : different divisors are supported, DR: [2, 4, 8], DS: [2, 4, 8]          
       - TB1 : SFGI = 1 (SFGT = 8192/fc), FWI = 8 (FWT = 1048576/fc)          
       - TC1 : NAD is NOT supported, CID is supported          
       -  HB : 80           
Answers to magic commands (GEN1): NO          

Valid ISO14443A Tag Found - Quiting Search

And using the `hf mfdes info` from the latest Iceman's fork gives:

Is it possible to find what DESFire class it is?

I guess the supported ciphers can help but I haven't fully read and understood the full specifications of the cards...

Thank you for your help smile

Re: How to detect DESFire EV1 vs EV2 vs DESFire (MF3ICD40)

Looking at the pdf http://www.nxp.com/documents/short_data … X2_SDS.pdf
there is ways to identify the new EV2.  Among one, some new authentication modes like AuthenticateEV2First and AuthenticateEV2NonFirst.  Not to mention a lot of new commands like the proximity check.

Re: How to detect DESFire EV1 vs EV2 vs DESFire (MF3ICD40)

Hello,

are you still working on this?

You can distinguish between DESFire (MF3ICD40), DESFire EV1 and DESFire EV2 by the GetVersion Command (0x60).
The "hf mfdes info" from the iceman repo is already using this command.

With Hardware Major Version Byte you can detect DESFire Version:
(in iceman repo "PrintAndLog("      Version        : %d.%d",resp.d.asBytes[10]")
- 0x00 -> DESFire (MF3ICD40)
- 0x01 -> MIFARE DESFire EV1
- 0x12 -> MIFARE DESFire EV2

How about you make a PR on github to my fork,  and I'll merge it smile

can do this, but will possibly last some time (multiple weeks not unrealistic)
Had worked with a borrowed proxmark 3 before, only as client user, no development.

But I'm planning to buy one proxmark 3 in the near future for rfid evaluations.

Re: How to detect DESFire EV1 vs EV2 vs DESFire (MF3ICD40)

Btw,  I'm looking at it.  The version bytes is in BCD form,  where did you find the identification list of the high version byte?

where did you find this information? Can't remember exactly, but it's not in the datasheet. I'm wrong?

found the information by reading out different DESFire Cards and I think it's in the datasheet also.

Re: How to detect DESFire EV1 vs EV2 vs DESFire (MF3ICD40)

Yes, that part is in the datasheets.

Don't know, Haven't seen it in the ev1 or old desfire datasheets.  I don't have the full datasheet for Ev2.

There is no list in the datasheets. But in every DESFire datasheet there is an example reply of the GetVersion (0x60) command.
And from that example answers you can get the version byte info.

My DESFire cards replyed all according to the list, that I posted earlier.

Re: How to detect DESFire EV1 vs EV2 vs DESFire (MF3ICD40)

ok, unclear of me.  I also found the old desfire and ev1 Getcommand instruction.  I don't have ev2 to verify it.
However,  the version you are suggesting is two byte long.  byte 10 and 11. 
So for EV2 is it  1.2? or 12.0 ?   (major version 1,  minor version 2)  or (majorversion 12 , minor 0)

I can push some changes tonite and you can test it out for me?

Re: How to detect DESFire EV1 vs EV2 vs DESFire (MF3ICD40)

Hello,

I posted only Hardware Major Version Byte, in your example it is Byte 10,
if it is really BCD coded, it will be 12.X for DESFire EV2.

can't test, cause I don't have a proxmark 3 at the moment.
will buy it soon wink

Re: How to detect DESFire EV1 vs EV2 vs DESFire (MF3ICD40)

I pushed some changes,  it will not find the EV2 yet since I'vent found a EV2 datasheet where it explains the actual major byte value it gonna use.   It looks for  major 1, minor 2 in this version.
Maybe you have a friend who has a pm3 and a EV2 tag to test it for me.

Re: How to detect DESFire EV1 vs EV2 vs DESFire (MF3ICD40)

I read out diffrent DESFire cards ... (answer to getVersion 0x60)

DESFire 4K (MF3ICD40)
---------------------
04 01 01 00 02 18 05
04 01 01 00 06 18 05
< 7 Byte UID > <5 Byte Batch No> <CW> <Year>

DESFire  EV1  2K  17pF
----------------------
don't have one, but would be:
04 01 01 01 00 16 05
04 01 01 01 04 16 05
< 7 Byte UID > <5 Byte Batch No> <CW> <Year>

DESFire  EV1  4K  17pF
----------------------
04 01 01 01 00 18 05
04 01 01 01 04 18 05
< 7 Byte UID > <5 Byte Batch No> <CW> <Year>

DESFire  EV1  8K  17pF
----------------------
04 01 01 01 00 1A 05
04 01 01 01 04 1A 05
< 7 Byte UID > <5 Byte Batch No> <CW> <Year>

DESFire  EV2  2K  17pF
----------------------
04 01 01 12 00 16 05
04 01 01 02 00 16 05
< 7 Byte UID > <5 Byte Batch No> <CW> <Year>

DESFire  EV2  4K  17pF
----------------------
04 01 01 12 00 18 05
04 01 01 02 00 18 05
< 7 Byte UID > <5 Byte Batch No> <CW> <Year>

DESFire  EV2  8K  17pF
----------------------
04 01 01 12 00 1A 05
04 01 01 02 00 1A 05
< 7 Byte UID > <5 Byte Batch No> <CW> <Year>

I think, this is helpful wink

Re: How to detect DESFire EV1 vs EV2 vs DESFire (MF3ICD40)

and there it is, in black and grey,  major version byte 0x12. So odd.
I think I changed my detection yesterday on github.
