Mifare DESfire card Authentication!!!!!

Look in "Mifare DES Fire Features and Hints V1.0". Chapter 2.3.3 contains the DES algorithms used by the DES Fire Card. If you use these algorithms an authentication will be possible.
Be careful with the resultig session key. If you authenticate with a single DES the session key will also be a single DES. (Copy the first 8 Bytes into the following 8 Bytes)

Good luck!

Important observation: it is not the usual CBC computation.

The second block of data is XOR'd before the DES. (I was told it is 'inverted CBC' -- RSA's site says

there are over 7 ways to do triple DES!). My CBC algorithms all XOR'd the data with previous block after

the DES. The Philips documentation diagrams it correctly, but it's not obvious.

So although your first block (rndA) will be correct (because ICV is 0's), your rndB' will not - and you get AE,

authentication error.

Hello
I need help. I working with DesFire card.
I want to authenticate a card. Specifics of desfire card says that master key of card is 0x00(16 Bytes).So it means i have to use DES for enciphering/deciphering.

1-) Authenticate = > Send 0x0A(command) 0x00(KeyNo) Response => AF 91 79 BA 9A AE 1C 71 F2

So RNDB which enciphered with masterkey is => 91 79 BA 9A AE 1C 71 F2

2-)Then i deciphered RNDB(i used DES with init-vector 0x00(8 Bytes), master-key 0x00(8 Bytes)) so clear RNDB = > 0F 67 06 85 0E 2F A4 03

3-) Then I rotated left RNDB. RNDB' = > 67 06 85 0E 2F A4 03 0F

4-) I selected RNDA as 11 22 33 44 55 66 77 88

5-) (RNDA + RNDB') = > 11 22 33 44 55 66 77 88 67 06 85 0E 2F A4 03 0F

5-) I deciphered (RNDA + RNDB') value with using DES function mode CBC-1 and i obtained CD 72 DF C6 E6 D0 40 A4 63 15 30 22 6F 75 4F 8D

6-)As a final i sent this last value with 0xAF => AF CD 72 DF C6 E6 D0 40 A4 63 15 30 22 6F 75 4F 8D
and i got 0xAE that it means authenticate error.

Can You check this values? I don't know where is the fault.

Thanks very much for helping.

Hello.

Write you e-mail. I will send for you DesFire card documents.

HI Can someone send me the "Mifare DES Fire Features and Hints V1.0". doc also to ftb06600 at gmail.com

thanks

Hello All
Could you give me Mifare DES Fire Features and Hints V1.0 document
at my email address [email protected]

because I cannot solve reading desfire ev1
using iso 14443
i already select the card an get the 7 digit serial number
and it done.
But when i am doing RATS command and APDU command it doesnt work.

I am using ACR120U reader and i Already succeess reading mifare philps 4k using the API.
But when i do it in the DESfire EV1 thats cannot worked
this are the steps that i done:

import acs.jni.ACR120U;

public class ConnectDesfire {

ACR120U deviceReadDesf;
byte rSerialNumber;

public ConnectDesfire()
{
deviceReadDesf = new ACR120U();
rSerialNumber = new byte[10];


short conn= deviceReadDesf.open(ACR120U.ACR120_USB1); // succsess
if(conn != 0) System.out.println("Error with code "+conn);

short valueSelect = deviceReadDesf.select(conn, new byte[1],
new byte[1], rSerialNumber); // Success
if(valueSelect != 0) System.out.println("Error with code "+valueSelect );

// rats
byte fsdi = 1 ;
byte atslen[] = new byte[1];
byte[] ats = new byte[16];
short resRats = deviceReadDesf.rATS(conn, fsdi, atslen, ats); // failed dont khow why error -3030
if(resRats != 0) System.out.println("Res Rats failed = " + resRats);

//apdu
byte rData[] = new byte[16];
xLen[0] = 0;
xData[0] = (byte) Integer.valueOf("60", 16).shortValue();
rLen[0] = 0;
rData[0] = 0;
short resAPDU=deviceReadDesf.xchAPDU(ACR120U.ACR120_USB1, true, xLen, xData, rLen, rData);
if(resAPDU !=0) System.out.println("Failed xchAPDU val= "+con);
// failed error -13.... sory i forgot the code

closeConnection(ACR120U.ACR120_USB1);
}

public static void main(String[] args)
{

ConnectDesfire a = new ConnectDesfire();
}
}


So could you share the document Mifare DES Fire Features and Hints V1.0 to me?

Hi.

Send me please the Mifare DESFire Features and Hints V1.0 email address is green_troll(at)rambler.ru

best regards.

Hi,

I'm also interested in the document
"Mifare DES Fire Features and Hints V1.0"

Can someone give me a hint where to get it
or email it to me.
email: schinger(at)gmx.de

thanks

Hi,
I need to acces a DESfire Card through the PC/SC interface, I can't find any usefull information.
It would be nice if somebody sends me the "Mifare DES Fire Features and Hints V1.0" document and some Information on which APDUs to use to s25534 (at) fh-aschaffenburg.de

regards lukas

M094510 - Mifare DESFire Feature and Hints
M075040 - DESFire DataSheet


Both document will help you work on DESfire card. To apply the documents you should go through NXP's rep or Vendor who you got card from. They are not public document.

Hello, somebody could send the same document: "Mifare DES Fire Features and Hints V1.0". to ruben.garcia at telvent.com
Thanks

I asked for Hints for DESfire etc, hoping I would recieve it by mail.
Is there somebody who knows if there will be a response or is this just asking,getting nothing ;-)

Still hoping - [email protected]
