MIFARE DESFire EV1 contactless multi-application IC
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 commands are the same for MF3ICD(H)81, MF3ICD(H)41 and MF3ICD(H)21, the
command details are available in
Ref. 1
. Only the memory size and input capacitance are
different between the devices.
8.5 Available file types
The files within an application can be any of the following types:
Standard data files
Backup data files
Value files with backup
Linear record files with backup
Cyclic record files with backup
8.6 Security
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 MIFARE
DESFire EV1 keys contribute to gain an effective anti-cloning mechanism and increase
the security of the original key; see
Ref. 7
.
Prior to data transmission a mutual three pass authentication can be done between
MIFARE DESFire EV1 and PCD depending on the configuration employing either 56-bit
DES (single DES, DES), 112-bit 3DES (triple DES, 2K3DES), 168-bit 3DES (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 options of secure communication between MIFARE
DESFire EV1 and PCD:
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.
Find more information on the security concept of the product in
Ref. 1
. Be aware not all
levels of security are recommended. The recommended secure handling of the product
can be seen in
Ref. 2
and in
Ref. 11
