MSP432P401R: Security on MSP-GANG - Prevent readback of bin files

MSP432P401R: MSP-GANG - Keeping files secure from CM

Part Number: MSP432P401R

Questions about MSP-GANG programmer for programming MSP432P401R. 

  1. From the user guide, it looks like Interactive mode is the only way to load binary files onto the programmer. Is this true?
  2. When we just have Go and Verify options enabled in the image file that is shared (the binary file is not shared), is it possible to copy the image onto the programmer?
  3. The user guide states that the only files supported on the SD Card are binary files (which are unencrypted). Is this true?
  4. Is the only security feature on the image file password protection or hardware fingerprint protection. Does the software encrypt the binary image as well so that even if the image is not password protected with only Go and Verify options enabled, then sharing the image file would ensure that the binary image cannot be reverse engineered from the image file.

Customer's goal is to keep their binary files secure, while allowing CMs to be able to update the image files on the programmer (if needed) easily.

    1. Actually, you save the image file, including the code and the programming configuration.

    2. It depends on whether you have lock the MSP430

    3. I think it is the image file.

    4. I think yes, because customer need to know how to analysis image file.

    I think the most important thing to protect the code is that:

    1. Make sure customer can't analysis  the image/binary file

    2. Make sure customer can't read the code out from MSP430. You need to secure the BSL and JTAG port.
