Modern cryptography allows for making DRM incredibly hard to break. And the disadvantage of "hardware attestation" DRM is that you have to break it not once, on a single device, the way you do to dump a "protected" movie, but on every single device that you want to use.
Funny, I have a related proposal: make it illegal to sell hardware and distribute software. Or at least, if you distribute software, we don’t buy your hardware. The idea is to force hardware companies to release the complete user manual for their hardware, and incentivise them to simplify and standardise their hardware interfaces.
What I did forget was forbidding them to arbitrarily restrict what kind of software can run with their hardware, which they could if the hardware hashes the software & verifies a signature before running it. But it would seem your separation between CPU and storage takes care of that.
There's also tons of value in a boot ROM that can't be accidentally erased to add low level DFU routines.
My intention with this is to make sure that if someone were to desolder the flash chip and reprogram it, they could completely own the device without the device or SoC manufacturer having a say in it or a way to prevent or detect it.
Example: I’m perfectly fine with my Touch ID sensor having a crypto-paired link to my SOC so that someone can’t swap in a malware-sensor at a border checkpoint; I also don’t want my device (or websites) to be able to discriminate against me installing my own homemade sensor. What that looks like in practice is close to what we have now, but not quite there yet — and is definitely not ‘no crypto-pairing at all’, as a ban on key material would enforce.
Not my preference, but they seem so far ahead of other ROMs right now that I use it still.
I do believe people have built and installed it on other devices without too much trouble, but I don't think that'll ever be supported.
No, you just need to make it illegal to have the bootloader contain hardcoded key material and use it for verifying the code it loads.
Not that it changes much. It really should be illegal to enforce "secure boot" with no way for the device owner to opt out of it or enroll his own keys.
Micro is now nano, not amendable to modification, and even if it was theoretically possible, hardware is a super-easy target for legislation.
> Alternatively, just make it illegal to ship any kind of initial bootloader as part of a CPU's/SoC's mask ROM
If you had the political means to enact such legislation, you could legislate much cleaner and easier ways to deal with the problem.
I find myself saying this a lot but I still can't quite figure our why people keep seeking technical solutions to political problems.
I mean, these things aren't comparable, in some limited cases the naive approach might help but insisting on it while neglecting political action is worse than doing nothing.
funny how you think the solution to people imposing their will on you is to impose your will on others
also, the solution you propose wouldn't work because signed firmware
Also, governments are supposed to act in the interest of people.
