Hi Adnan,
The authentication is always initiated from the reader by sending the “start authentication command”. It is the same also for the other MIFARE products. If you want to authenticate with key A, you use command 0x60, for key B, you use 0x61. Additional you must add the block for which sector you want to authenticate. Let us say, the first sector. This is shown in the example on page 9. Therefore you send 0x6000.
You should also read the details of the authentication in the datasheet on page 7 (see link below).
Table 3 shows a calculated example of the communication between SAM and Classic.
