Reply To: Authentication Problem Desfire EV1 with AES

[Ingo Robin]

Hello,

having still a problem with authentication.
When calling method authenticate following error occures:

com.nxp.nfclib.exceptions.InvalidResponseLengthException: Authentication Error

      desFireEV1.selectApplication(0);



            byte[] KEY_AES = new byte[] {

                    (byte) 0xAA,(byte) 0xAA,(byte) 0xAA,(byte) 0xAA,(byte) 0xAA, (byte) 0xAA,(byte) 0xAA,(byte) 0xAA,

                     (byte) 0xFF,(byte) 0xFF, (byte) 0xFF,(byte) 0xFF,(byte) 0xFF,(byte) 0x5F, (byte) 0xFF,(byte) 0xFF,



            };



           Key key = new SecretKeySpec(KEY_AES,"AES");

           KeyData keyData = new KeyData();

           keyData.setKey(key);

          desFireEV1.authenticate(0, IDESFireEV1.AuthType.AES, KeyType.AES128, keyData);

Need help!!!
