Product short data sheet
PUBLIC
7.5.4 SAM data processing commands
7.5.5 SAM general commands
7.5.6 SAM power saving commands
Such an authentication proves that both the SAM and the host contain the same secret,
namely a DES, 3DES or AES key, and generates a session key for further cryptographic
operations.
SAM_Verify_MAC
The SAM_Verify_MAC command verifies the MAC which was sent by the DESFire PICC
or any other system based on the given MACed plain text data and the currently valid
cryptographic key.
To do so, the plain data is enciphered in cipher block chaining send mode. Padding bytes
(if applicable) are generated internally for cryptographic operation.
SAM_Generate_MAC
The SAM_Generate_MAC command creates a MAC which is meant to be sent to the
DESFire PICC or any other system based on the given plain text data and the currently
valid cryptographic key.
To do so, the plain data is enciphered in cipher block chaining send mode. Padding bytes
(if applicable) are appended automatically for cryptographic operations but are not
transmitted.
SAM_Decipher_Data
The SAM_Decipher_Data command deciphers data packages sent by a DESFire PICC,
any other system or a MIFARE card based on the currently valid cryptographic key and
returns plain data to the PCD.
To do so, the plain data is deciphered in CBC receive mode. CRC and padding bytes are
checked for validity automatically.
SAM_Encipher_Data
The SAM_Encipher_Data command creates data packages which are meant to be sent to
a DESFire PICC or any other system based on the given plain text data and the currently
valid cryptographic key.
To do so, the plain data is enciphered in cipher block chaining send mode. CRC and
padding bytes are appended automatically.
SAM_GetVersion
The SAM_GetVersion command returns manufacturing related data of the SAM.
SAM_Sleep
Forces the SAM to put a connected MFRC52X into sleep mode and itself into idle mode to
reduce power consumption.
The SAM will answer the command and afterwards switch to idle mode.
