I registered to your docstore.nxp.com
I have permission to Mifare Desfire EV1 but this datasheet doesnt contain chapter 4.1 with 3 mutual pass authentication example about you wrote in the 6th post.
Can you send me where i can find datasheet :MIFARE DESFire EV1, Functionality of implementations on smart card controllers
with chapter 4.1 example values
Thx.

Re: Reply To: Mifare DesFire Authentication
9. June 2016 at 11:51 in reply to: Mifare DesFire AuthenticationIt's different value for RndA.
And you wrote on card side RndA is encrypted with IV=00…00
It means on card side is everytime use IV=00...00 for 3DES?
PLease send me correct pdf for MIFARE DESFire EV1.
Thank you

I have litle bit problem with your description
On card side:
IV=e(RndA+RndB) I dont have this value. I have only e(RndA+RndB').If I have to use IV=e(RndA+RndB) what is vector for encrypt?
And this vector is array with length 16?
I thing my problem is in last step and IV on reader side.Maybe I use wrong vector.
I send you image with my implementation and which IV I used for each steps.
Thx.

No I dont forget rotation.
And received data in third step are totaly different.
Any item in array received and decrypth in third step is not same with my RndA.
Thx
