Title: Bootloader Encryption
Post by: ikhwan_h17f on July 07, 2010, 11:37:31 PM

Hello, let me introduce my self, I am favian. Now I'm doing research about bootloader in AVR, especially in ATMega 64.

I have downloaded your FBOOT_GUI, your bootloader v2.1, and also tried your tutorial in http://www.societyofrobots.com/bootloader_50_robot.shtml#debug (http://www.societyofrobots.com/bootloader_50_robot.shtml#debug)

I'm happy it works. But, there is something I wanna ask to admin or anyother people...
First, Is FBOOT_GUI using the same source code with bootloader v2.1? If it's not, would you like to share the source code of FBOOT_GUI before being compiled (C/C++ code or another else)?

Second, If I want to add encryption to this bootloader program, what should I do? What encryption must be used (RSA/DES/ etc)?

thanks.


regards
Favian D

that bootloader was developed by Danni at AVRfreaks.

create yourself an http://www.avrfreaks.net (http://www.avrfreaks.net) account and log in then go here:

i'm curious why you might want to encrypt the bootloader?

" i'm curious why you might want to encrypt the bootloader? "

I just wanna develop the security of that bootloader application so that my firmware can't be copied  :)


Thanks four your link.
