8.4.1.2 Asymmetric key cryptography (MIFARE SAM AV2 mode only)
8.4.1 Cryptography
8.4 Cryptography and key handling
AV1 compatibility mode supports symmetric key cryptographic algorithms while MIFARE
SAM AV2 mode supports both symmetric and asymmetric cryptography.
MIFARE SAM AV2 offers support in several commands for various symmetric key
cryptographic algorithms.
DES and TDEA
DES keys (56 bit) and 2TDEA keys (112 bit) are stored in 16 byte strings. 3TDEA keys
(168 bits) are stored in 24 byte strings.
DES keys (56 bit) are stored in the same format as the 2TDEA keys: the DES key is
stored twice to form a 2 key TDEA key where the 2 keys are identical.
AES
AES keys are stored in strings of 16 bytes or 24 bytes depending on whether it is an AES
128-bit key or an AES 192-bit key.
AES always operates on 16 bytes. Therefore data streams are always padded to a length
of multiples of 16 bytes.
For details of the AES standard please refer to publicly available standard
AES MACing
MIFARE SAM AV2 supports standard CMAC [ref. 15] for AES. Padding is done according
to the standard. By default, the CMAC is truncated to 8 bytes, except if requested
explicitly otherwise by the user (SAM_Generate_MAC and SAM_Verify_MAC
commands).
An alternate MAC truncation scheme is used for MIFARE Plus commands for the AV2
mode SAM-Host communication protection and possible via SAM_Generate_MAC and
SAM_Verify_MAC commands.
MIFARE Classic
MIFARE SAM AV2 supports MIFARE Classic Crypto-1 authentication and encryption.
MIFARE SAM AV2 supports RSA encryption, decryption, signature generation and
signature verification according to
via the PKI commands.
RSA encryption and decryption:
support RSA decryption. It is used by the PKI_UpdateKeyEntries command. The
supported algorithm is RSAES-OAEP
function and a Mask Generation Function (MGF). For the MGF, the SAM supports SHA-1,
SHA-224 and SHA-256 for hashing (see Ref. 9 for the various SHA variants); the MGF
used is the one specified by
