You still can have hardware backdoor in one of the ICs. You need to check them all. So, step one: produce your hardware on your own.

- EvanAnderson 6y agoHow do you verify that the fab didn't insert any backdoors and made your part strictly to-spec? Fabrication-time attacks are an interesting vein of content to research. There are some good papers and talks out there if you do some quick searching.
- namibj 6y agoIf you eliminated vulnerabilities due to evil doping, you can use a free electron laser to holographically capture the 3 dimensional structure inside, and then you can compare the enlarged+scanned/digitally-captured patterns with those that you expect from simulating the holographic imaging. In certain settings this should work non-destructively, but that might require something like lapped (grinding the backside after fabrication to thin out the substrate) non-stacked >=22 nm chips.
