Introduction DESFireUI Demo Software

Semiconductors 3

DESFire UI Software Demo

Step 1: PC to Pegoda communication

Semiconductors 4


Step 2: Activate the T=CL

0 = 106 kbps1 = 212 kbps2 = 424 kbps3 = 848 kbps

Semiconductors 5


Step 3: Security & PICC command level

Semiconductors 6

• After power up, card selection and initialization, application DESFire AID=0x000000 is selected(Card level = “root-directory”)

• All keys are default at 0x0000000000000000

• File commands can be used if there is an existing file in the selected Application

• 3 types of files can be create (Data, Value and Records)

• Maximum number of file is 16

• FID can range from 0 to 15

• File with Backup mechanism must have FID range from 0 to 7


Step 3: Status of “new” DESFire card

Semiconductors 7


Step 4: Create an Application with AID=0x123456

Set the number of key used in this application to maximum (14 keys).

Set the condition for Application Master key

Set Application Master Key to be used when changing the Application Keys

Confirm command with button

Semiconductors 8


Step 5: Select Application AID=0x123456

Semiconductors 9


Step 6: Application command level

Semiconductors 10


Step 7: Create a Backup Data File with FID=0x02

Set the file communication encryption level to DES/3DES MACing

Setting the access conditions for the file (Key 1, 2 & 3 are being used for the different access)

Set the file size to 15 bytes (take note of the actual memory space used)

Create the file with Backup mechanism

Semiconductors 11


Step 8: Authenticate with key #2 before writing data in fileKey 2 of the Application AID=0x123456 have to be used for data file writing of FID=0x02

Default key is always 0x00

Semiconductors 12


Step 9: Write data into file FID=0x02

Set offset from the beginning of the file as 0

Enter data to be written in Hexadecimal

Since this is a Backup file, data written must be validated by the Commit Transaction command

Semiconductors 13


Step 10: Authenticate with key #1 before reading from file

Semiconductors 14


Step 11: Read data from file FID=0x02

Semiconductors 15

• Start DESFireUI• Open Interface

- check “Automatically retrieve command times”• T=CL Commands

- Activate Idle- RATS- skip PPS

• Security Commands- Authenticate PICC with key 0- Format PICC

• PICC commands- Create Application with AID: 0x123456 and 1 (one) key(Change key access rights = 14)

- Select Application with AID: 0x123456


Demonstrate DESFire data rates (1)

Semiconductors 16

• Application Commands- Create Data File with File ID 0x11; file size 3872 bytes(plain communication, all access rights 14, NO backup)

• Reset Total Time• File Commands

- Data File Access; Read Data(FileID 0x11, Offset = 0, Length = 0)

• Read Total Read Time in Total Time Windows• Repeat a few times for consistent timings



Semiconductors 17

• T=CL Commands - Deselect - Change DSI to 2 and DRI to 2- Activate Wakeup- RATS- PPS

• PICC commands- Select Application with AID: 0x123456

• Reset Total Time• File Commands

- Data File Access; Read Data(FileID 0x11, Offset = 0, Length = 0)

• Read Total Read Time in Total Time Windows• Repeat a few times for consistent timings



Coding forDSI & DRI:

0 = 106 kbps1 = 212 kbps2 = 424 kbps3 = 848 kbps

Semiconductors 18

• Create an Application with AID=0xABCDEF– Application should have 6 keys– Creation/deleting of file require application Master Key– Authenticate with key #1 is needed for changing any key

• Create a Data File with FID=0xE– Communication of file is Full DES/3DES enciphering– Set access condition as: Read & Write & Read/Write (Key #2), Change AC

(Key #1)– File size is 64 bytes

• Create a Cyclic Record File with FID=0x2– Communication of file is DES/3DES MACing– Set access condition as: Read (Key #3) & Write & Read/Write (Key #4),

Change AC (Key #1)– Record size is 16 bytes– Number of record is 3
