Authentication
When changing to the Write tab, the Write Setup and Write Timing are shown.
Use Write Timing on the right side to set the timing parameters for writing. Under normal operat-
ing conditions, the default values can be used.
The programming of the transponder is performed by the Program Transponder button.
The blocks to be programmed are selected by selecting the box in the Write column.
Clicking the button Default restores the default setting.
With the Stop Transponder-Modulation button, the stop command is sent to the transponder
(this halts modulation until POR).
To leave the U9280M user interface, click on the Cancel button.
Figure 5-17. U9280M Authentication Tab
The RFID application kit can be used to demonstrate the encryption feature of the U9280M
read/write/crypto transponder. The PC-based software provides a user interface that enables
the configuration of the transponder. Furthermore, because the RFID application kit acts as a
base station, a real challenge/response authentication procedure can be carried out. The AUT64
encryption algorithm used in the U29280M is implemented as a part of the mask programming.
The algorithm is started by the button Start Authentication. The checksum result and encryption
response of the AUT64 are displayed in separate messages for the transponder and base sta-
tion. If both responses are equal, the AUT64 result displays OKAY; if unequal, the AUT64 result
displays Error AUT64.
The user can change the input parameters and key data of the encryption algorithm.
Note:
Remark: Data value in block 6 is restricted: The 3 LSB of each nibble must be different.
