    Hi,
    maybe I haven't given an important information.
    I want and useing keys of 8 byte.
    I believe that is different because I use DES_CBC Decrypt with key of 8 byte.
    Waiting for your feedback.
    Regards,

    Hi,
    I created a application with KeySetting1= 0xEF and KeySetting2 = 0x03.
    I succeed to do authentication with key of default (all 0) then I do the authentication, after selected the Application, with new key and the PICC returns 0xAE.

    Hi,
    It's right, I calculate session key with command authentication between card and reader.
    For me "App MasterKey" is Master Key of the Application with AID = 0x00.
    When I want change value with key I authenticate with old key (calculate at the end of this command the sessionKey) and send the command change key.
    This command return me AE.
    Regards
