Where,
PCD Key Number
– any value from 0x00 to 0x04
Key number 0x00 refers to PICC master key
Key numbers 0x01 to 0x03 refer to Application keys
AID
- Application identifier in the card to which the key belongs
Must be 000000 for PICC master key
PICC Key Number
- Key number to be used in the DESFire Authenticate command
Key (1-2-3)
- Can be DES/TDES or AES key
DES key: (Key 1 = Key 2)
TDES key: (Key 1 ≠ Key 2); (Key 1 = Key 3)
AES key: (Key 3 = all zeros)
