8.4.3 Key Storage (MIFARE SAM AV1 compatibility mode)
RSA signature generation and verification:
AV2 support RSA signature handling. It is used by the PKI_GenerateSignature,
PKI_VerifySignatures and PKI_UpdateKeyEntries commands. The supported algorithm is
RSASSA-PSS (see
commands expect the already hashed message mHash as input. The initial hash
operation (Step 1 and 2 of EMSA-PSS-Encode and EMSA-PSS-Verify,
calculated by this function.
Hashing algorithms (MIFARE SAM AV2 only):
SHA-224 and SHA-256 for hashing according to
available in AV2 mode via the PKI_GenerateHash command.
MIFARE SAM AV2 provides several key diversification methods. In both AV1 compatibility
mode and in MIFARE SAM AV2 mode, the MIFARE SAM AV1 key diversification methods
and new MIFARE SAM AV2 key diversification methods are available; however for AV2
only commands (i.e. MFP commands and the ULC_AuthenticatePICC) only the new
MIFARE SAM AV2 diversification methods are available.
MIFARE SAM AV2 in AV1 compatibility mode can only store symmetric keys.
MIFARE SAM AV2 can store up to 128 symmetric keys in up to 3 versions (only 2 versions
possible for 3TDEA keys and AES-192 keys).
The MIFARE SAM AV2 uses a Key Storage Table (KST) in order to store and manage
keys and attributes related to keys.
The KST holds 128 entries. Every entry contains positions to store three DES, three
2TDEA, two 3TDEA, three AES128, two AES192 or six MIFARE keys plus their attributes.
Every key entry is referred to by its index, the KeyNo.
Key reference number:
value 00h to 7Fh.
Key reference number of change entry key:
necessary for authentication to run a SAM_ChangeKeyEntry command.
The value FEh disables the need for authentication for key load.
The value FFh irreversibly locks the entire key entry.
Key version of change entry key:
entry specified for the change entry key. The key version has to be in the range of 00h to
FFh.
Reference number of key usage counter:
of the key usage counter entry which is automatically incremented each time this key
entry is used for authentication, see
