8.2.4 UID/serial number
8.3 MIFARE SAM AV1 compatibility mode vs. MIFARE SAM AV2 mode
The MIFARE SAM AV2 IC features a 7 byte unique serial number that is programmed into
a locked part of the non-volatile memory that is reserved for the manufacturer. This UID is
fixed and cannot be changed.
Unless stated explicitly otherwise, all information in this document refer to both the
MIFARE SAM AV1 compatibility mode and to the pure MIFARE SAM AV2 mode.
Commands only available in pure MIFARE SAM AV2 mode are flagged as "AV2 only".
Differences for commands different in SAM AV2 with respect to their corresponding SAM
AV1 compatibility version are listed explicitly as well.
The main differences between the AV1 compatibility mode and the AV2 mode are the
following:
•
•
•
•
•
PKI commands are only available in AV2 mode
AV2 mode introduces key classes: Host Keys, PICC keys, OfflineChange keys and
OfflineCrypto keys. All symmetric key entries are classified into one of them,
restricting the possible usage of the key entry.
AV2 mode improves the SAM access protection by replacing the AV1 compatibility
Host Authentication protocols with more secure variants.
AV2 mode improves the SAM-Host communication protection by replacing the AV1
compatibility increased security mode (based on CMACing) by three modes of secure
messaging after a host authentication (Plain, MAC Protection and Full Protection).
AV2 mode replaces and adds some key entry configuration options, offering more
flexibility in securing the SAM (e.g. regarding key dumping).
