    Hello

    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.

    It'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

    Hi

    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.

    Hi

    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
