Crack code protection


#1

It would be possible jump code protector of any microcontroller like microchip pic with chipwhisperer?

Thanks very much

Hi,

It’s probably not possible with all microcontrollers, but it’s definitely possible with some (see https://wiki.newae.com/Tutorial_A9_Bypassing_LPC1114_Read_Protect for an example of a ChipWhisperer being used to bypass code protection on a chip). How easy/possible it is to glitching code protection depends heavily on how they’re implemented. For example, it would have been much harder to glitch the LPC1114 from my link if max protection was the default instead of no protection.

Dear Alex,

Thanks very much for your reply,I will try bypassing code protection of some microcontrollers.
