FW encryption

[kagakuka]

Hi Guys,

I need your help to know about FW data encryption.

Question
Regarding to FW that is provided Sierra,such as AMSS/Bootloader/OPAT framework(.cwe files),
are these files encrypted ?
If yes, how is it decrypted inside the module? Who has the key for decryption?

Thank you.

Hi,

The files are encrypted. The tool which is used to update the firmware has to decrypt the files.

Thanks
