Mainstream contactless smart card IC
Value blocks are special counters where the stored value can be manipulated with
specific commands such as MF Increment, MF Decrement and MF Transfer.
These value blocks have a fixed data format enabling error detection and correction with
backup management to be performed. Value blocks are only available in security level 1.
A successful mutual authentication is required to allow any data operation.
8.1.2.1
Access conditions
The access conditions for every data block and the sector trailer itself are stored in the
sector trailer of the corresponding sector.
The access bits control the rights of memory operations using the secret keys A and B.
The access conditions may be altered after authentication with the relevant key and the
current access condition allows this operation.
Furthermore, value blocks are configured using the access bits.
8.1.3
AES keys
AES keys are not shown in the memory map. The keys are stored on top of the other data
and can be updated and used by referencing the so-called Key Number. In security
level 3, anti-tearing is supported for the update of AES keys as well as for the update of
the sector trailer. This anti-tearing mechanism is done by the PICC itself. The EEPROM
stays in a defined status, even if the PICC is removed from the electromagnetic field
during the write operation.
8.1.4
Multi-sector authentication
A new feature has been provided in security level 3 for data which is spread over multiple
sectors to improve transaction performance.
Providing that such sectors are secured with identical keys (key value and key type) only
one authentication is required to read and/or write data from these sectors. There is no
need to re-authenticate when accessing any data within these sectors. Therefore it is
possible to configure a card in such a way that operating with only one authentication is
needed in security level 3 to access all sectors.
8.1.5
Originality function
The originality function is implemented by an AES authentication with the originality key.
The authentication is performed in ISO/IEC 14443-4 protocol layer.
8.2 Card activation and communication protocol
The ISO/IEC 14443-3 anticollision mechanism allows for simultaneous handling of
multiple PICCs in the field. The anticollision algorithm selects each PICC individually and
ensures that execution of a transaction with a selected PICC is performed correctly
without data corruption from other PICCs in the field.
