our customer wants me to implement a bootloader on our HCS08SG16 via SCI and with encryption. Are there any libraries to do the decryption on the target? I did not find any information for the 8bit - Microcontrollers.
The encryption method is not defined - but it should not be the easiest method to break.
I want to take the doonstack - routines to do the erase and write access to the flash - this works already.
I think AES or DES or 3DES - encryption would be nice, but I did not find any hints according to this for my microcontroller - family.
Does somebody has an idea or a link for me?
Many thanks (and have a nice weekend)
