For More Info Visit: http://ultra96.org/product/medical-cybersecurity-platform

Hardware Requirements:

• Ultra96v2
• PMOD Adapter
• Heart Rate Sensor
• Ultra96 Power Supply
• TPM PMOD 2.0
• 16 GB SD Card
• USB to Micro USB Cable

Software Requirement:

• Chrome Browser
• TeraTerm
• Image File (Download Link)
• Win32DiskImager

Getting Started Steps

Step 1:

• Download the image file from the download link provided (http://ultra96.org/product/medical-cybersecurity-platform)
• Unzip the downloaded file to get the image file (Disk Image File /.img extension)
• Write the image file to a 16GB SD card using Win32DiskImager
• Once the write is successful, the SD card is ready

Step 2:

• Insert the prepared SD card into the SD card slot of the Ultra96v2
• Connect the micro USB to the Ultra96v2, the other end of the USB cable will be connected to the laptop
• Connect the PMOD adapter to the Ultra96
• Connect the heart rate sensor to the PMOD adapter using the grove cable
• Connect the TPM PMOD 2.0 to the vertically mounted PMOD adapter
• Connect the power adapter to the Ultra96v2 board

Once completed, your set up should look like the below images:

If you are unsure of the connection, please refer the following link for a video of the setup: https://www.youtube.com/watch?v=LtXzalxy2zc&t=6s

Step 3:

• Press the power button on the Ultra96v2 to turn on the board
• Give the board a few seconds to boot up, you will see blue lights flashing on the board to indicate that the boot is complete
• Now open the browser and enter the following IP Address: http://192.168.3.1:9090/
• You will be prompted by the browser to enter a password as shown below:

Password: xilinx

Once the password is entered, you will be able to access the home directory of Ultra96v2 via jupyter

Step 4:

• The home directory will look as follows:

• Click on “dashboards” from the list of folders

• Click on “secure-dashboard.ipynb” from the list of folders

• To start, click on Cell -> Restart & Run All

• Click on “Restart and Run All Cells”

• The Medical Cybersecurity Demonstration will be ready and will look like the picture shown below:

• Insert your finger into the finger the heart rate sensor
• You will see the heart rate values show up on the live graph
• Note: the respiration rate is artificially generated once the heart values are detected

All the buttons on the left are action Buttons:

• Attack FPGA (user) – Attempts to load an unauthenticated bitstream as non-root user. Blocked by ZU+ authorization checks.
• Attack FPGA (root) – Attempts to load an unauthenticated bitstream as root-user. Blocked by ZU+ authorization checks even when called by root.
• Attack RTOS App – Inserts attack in FreeRTOS application memory. Flagged by MicroArx monitor.
• Attack RTOS Kernel – Inserts attack in FreeRTOS kernel memory. Flagged by MicroArx monitor.
• Attack Linux Kernel – Attack to load unsigned file, against security policy of Linux. Flagged as issue requiring patch.
• Patch Linux – Mock patch to address “Attack Linux Kernel” attack. Makes point that even a secure system will need patches over time.
• Reset System – Resets the demo back to the starting point
• Restart System in Unsecure Mode - Restarts the demo in unsecure mode

Step 5:

• Properly shutting down the demo
• Select the click button next to “secure-dashboard.ipynb”
• Click on shutdown and the demo will be shutdown

• Click on New -> Terminal

• In the terminal, enter “shutdown now”

• The board will shutdown following the proper shutdown routine
• Note: This step will help in starting the demo back up again in the future
• Disconnect power to the Ultra96v2
