comment How cryptographically secure was the original WW2 Enigma machine, from a modern viewpoint?
If I understood the real WW2 events which lead to the cracking of Enigma correctly, the operator mistakes were useful to actually discover the "algorithm" itself. How would modern cryptanalysts with modern tools to their disposal discover the algorithm of an Enigma-like machine without putting their hands on a physical copy of the machine?

@mikeazo : you are right, I see now that my formulation was unclear. I corrected it. I don't know what percent of microcontrollers have this feature, but I assume either all or at least most of the modern ones.

@mikeazo : microcontrollers have fuses which prevent reading the contents. You would need an electron-microscope and lot of time and expertise to read out the contents of a protected flash memory. Much higher costs than developing the desired software from scratch.

@fgrieu : the method described does not prevent theft in the form of deliberately leaking the software (due to a very small team this risk is negligible), but that was not the intention. The intention was to prevent theft from the publicly released update.
