+## Authentication Deep Dive
+
+### DES/3DES Authentication Protocol
+
+#### Phase 1: Initial Authentication Request
+```
+PCD → PICC: 90 0A 00 00 01 [KeyNo] 00
+             └─ Authenticate command (0x0A)
+```
+[Source: DESFire DES authentication D40-DES authentification.pdf, line 7]
+
+#### Phase 2: PICC Responds with Encrypted RndB
+```
+PICC → PCD: [Ek(RndB)] 91 AF
+             └─ 8 bytes encrypted RndB
+```
+[Source: DESFire DES authentication D40-DES authentification.pdf, line 9]
+
+#### Phase 3: PCD Prepares Response
+1. Decrypt RndB using key
+2. Generate RndA (8 bytes)
+3. Rotate RndB left by 1 byte
+4. Concatenate: RndA || RndB_rotated
+5. Encrypt with CBC mode, IV from previous response
+
+[Source: DESFire DES authentication D40-DES authentification.pdf, lines 23-39]
+
+#### Phase 4: Send Encrypted Challenge
+```
+PCD → PICC: 90 AF 00 00 10 [Ek(RndA || RndB_rot)] 00
+```
+[Source: DESFire DES authentication D40-DES authentification.pdf, line 41]
+
+#### Phase 5: Verify PICC Response
+```
+PICC → PCD: [Ek(RndA_rot)] 91 00
+```
+PCD decrypts and verifies rotated RndA matches
+[Source: DESFire DES authentication D40-DES authentification.pdf, lines 43-56]
+
+### AES Authentication Protocol
+
+Similar flow but with 16-byte blocks:
+1. Uses command 0xAA instead of 0x0A
+2. RndA and RndB are 16 bytes each
+3. AES-128 in CBC mode
+4. Session key derivation differs
+
+[Source: DESFire.py, lines 79-144]
+
+### EV2 Authentication Protocol
+
+#### EV2First Authentication
+1. **Capability Exchange**:
+   ```
+   PCD → PICC: 71 [KeyNo] [Len] [PCDcap2]
+   PICC → PCD: [TI] [PDcap2] [PCDcap2] AF
+   ```
+   [Source: desfire_ev3_authentication.pdf, lines 18-25]
+
+2. **Complete Authentication**:
+   - Similar challenge-response
+   - Generates Transaction Identifier (TI)
+   - Establishes secure channel
+
+#### EV2NonFirst Authentication
+```
+PCD → PICC: 77 [KeyNo]
+```
+Requires previous EV2First in same session
+[Source: desfire_ev3_authentication.pdf, lines 27-30]
+
+### Session Key Generation
+
+#### DES Session Key (8 bytes)
+```
+SessionKey = RndA[0:4] || RndB[0:4]
+```
+[Source: DESFire DES authentication D40-DES authentification.pdf, lines 66-71]
+
+#### 2K3DES Session Key (16 bytes)
+```
+SessionKey = RndA[0:4] || RndB[0:4] || RndA[4:8] || RndB[4:8]
+```
+[Source: DESFire.py, lines 135-136]
+
+#### 3K3DES Session Key (24 bytes)
+```
+SessionKey = RndA[0:4] || RndB[0:4] ||
+             RndA[6:10] || RndB[6:10] ||
+             RndA[12:16] || RndB[12:16]
+```
+[Source: DESFire.py, lines 138-141]
+
+#### AES Session Key (16 bytes)
+```
+SessionKey = RndA[0:4] || RndB[0:4] || RndA[12:16] || RndB[12:16]
+```
+[Source: DESFire.py, lines 143-144]
+
+### CMAC Calculation
+
+#### Subkey Generation
+```python
+# Generate L by encrypting zero block
+L = AES_Encrypt(Key, 0x00000000000000000000000000000000)
+
+# Generate K1
+K1 = L << 1
+if MSB(L) == 1:
+    K1 = K1 XOR Rb  # Rb = 0x87 for AES
+
+# Generate K2
+K2 = K1 << 1
+if MSB(K1) == 1:
+    K2 = K2 XOR Rb
+```
+[Source: mifare_desfire_crypto.c, lines 95-123]
+
+#### CMAC Calculation
+1. Pad message if needed (0x80 0x00...)
+2. XOR last block with K1 (complete) or K2 (incomplete)
+3. CBC encrypt all blocks
+4. Final block is CMAC
+

+```
+[Source: protocols.h, line 359]
+
+#### Credit Operation
+```
+Command: 0C [FileNo] [Amount-4B]

+### Transaction Mechanism
+
+For Backup and Value files:
+1. Perform operations (Write, Credit, Debit)
+2. Changes are pending until:
+   - **CommitTransaction (0xC7)**: Apply changes
+   - **AbortTransaction (0xA7)**: Discard changes
+

+## Cryptographic Implementation
+
+### Key Diversification (AN10922)
+
+#### Algorithm Steps
+1. **Prepare Diversification Input**:
+   ```
+   M = [Constant] || [UID] || [AID] || [SystemIdentifier]
+   ```
+   Constants:
+   - 0x01: AES-128
+   - 0x21: 2K3DES
+   - 0x31: 3K3DES
+   [Source: mifare_key_deriver.c, lines 10-17]
+
+2. **Calculate Diversified Key**:
+   ```
+   DiversifiedKey = CMAC(MasterKey, M)
+   ```
+   [Source: mifare_key_deriver.c, lines 101-177]
+
+### Secure Messaging
+
+#### MACed Communication Mode (0x01)
+- Commands sent in plain
+- Response includes 8-byte CMAC
+- CMAC covers: Response Data + Status Code
+[Source: various implementation files]
+
+#### Full Enciphered Mode (0x03)
+- Command data encrypted after authentication
+- Response data encrypted
+- Both include CMAC for integrity
+- Uses session keys and IVs
+
+### IV Generation
+
+#### EV1 IV Handling
+- Initial IV: All zeros
+- Subsequent: Last block of previous crypto operation
+
+#### EV2/EV3 IV Generation
+```
+IV = EncryptedFlag || TI || .pdfCtr || ZeroPadding
+```
+- TI: Transaction Identifier (4 bytes)
+- .pdfCtr: Command Counter (2 bytes)
+[Source: hf_desfire.c and crypto implementations]

+
+## Communication Modes
+
+### Plain Communication (0x00)
+- No encryption or MACing
+- Suitable for public data
+- Fastest performance
+- No authentication required for read
+
+### MACed Communication (0x01)
+- Data transmitted in plain
+- 8-byte CMAC appended to responses
+- Integrity protection
+- Requires authentication
+
+### Fully Enciphered Communication (0x03)
+- All data encrypted
+- CMAC for integrity
+- Maximum security
+- Requires authentication
+- Performance impact

+
+## Implementation Examples
+
+### Example 1: Creating an Application with AES Keys
+```python
+# Create application 0x000001 with 5 AES keys
+aid = [0x01, 0x00, 0x00]
+key_settings = 0x0F  # All keys changeable, free directory
+num_keys = 0x85     # 5 keys, AES encryption (bit 7 set)
+
+command = [0xCA] + aid + [key_settings, num_keys]
+response = send_command(command)
+```
+
+### Example 2: Secure File Write with MACing
+```python
+# Authenticate first
+authenticate_aes(key_no=0x01, key=master_key)
+
+# Create MACed file
+create_std_file(file_no=0x01,
+                comm_settings=0x01,  # MACed
+                access_rights=0x0000,  # Free access
+                file_size=32)
+
+# Write data (will be MACed automatically)
+write_data(file_no=0x01, offset=0, data=b"Secure data here")
+```
+
+### Example 3: Value File Transaction
+```python
+# Create value file with limits
+create_value_file(file_no=0x02,
+                  lower_limit=0,
+                  upper_limit=10000,
+                  initial_value=1000,
+                  limited_credit=True)
+
+# Perform operations
+credit(file_no=0x02, amount=500)   # Balance: 1500
+debit(file_no=0x02, amount=200)    # Balance: 1300
+
+# Commit all changes
+commit_transaction()
+```
