Product short data sheet
8.5 Available file types
8.6 Security
If this rollback is necessary, it is done without user interaction before carrying out further
commands.To ensure data integrity on application level, a transaction oriented backup is
implemented for all file types with backup. It is possible to mix file types with and without
backup within one application.
As the command are the same for all MF3ICD81, MF3ICD41, MF3ICD21, the details on
the commands can be retrieved from
the three products.
The files within an application can be of different types as:
The 7 byte UID is fixed programmed into each device during production. It cannot be
altered and ensures the uniqueness of each device.
The UID may be used to derive diversified keys for each ticket. Diversified MF3ICD81
keys contribute to gain an effective anti-cloning mechanism and increase the security of
the original key, see
Prior to data transmission a mutual three pass authentication can be done between
MF3ICD81 and PCD depending on the configuration employing either 56-bit DES (single
DES, DES), 112-bit DES (triple DES, 3DES), 168-bit DES (3 key triple DES, 3K3DES) or
AES. During the authentication the level of security of all further commands during the
session is set. In addition the communication settings of the file/application result in the
following option of secure communication between MF3ICD81 and PCD:

Standard data files
Backup data files
Value files with backup
Linear record files with backup
Cyclic record files with backup
Plain data transfer (only possible within the backwards compatible mode to
MF3ICD40)
Plain data transfer with cryptographic checksum (MAC):
Authentication with Backwards compatible mode to MF3ICD40: 4 byte MAC
All other Authentications based on DES/3DES/AES: 8 byte CMAC
Encrypted data transfer (secured by CRC before encryption):
Authentication with Backwards compatible mode to MF3ICD40: A 16 bit CRC is
calculated over the stream and attached. The resulting stream is encrypted using the
chosen cryptographic method.
All other Authentications based DES/3DES/AES: A 32 bit CRC is calculated over the
stream and attached. The resulting stream is encrypted using the chosen
cryptographic method.
