    Who Watches the Silicon?

    Curated by HackerTube · 11 videos · 9 hr 34 min

    A descent through the layers of a computer you cannot see or audit, ordered from the peripherals inward to the CPU, its secret co-processors and firmware, then out to the board and the supply chain. Most of these are HN gems with modest view counts, and HN brings them up whenever Intel ME, backdoors or hardware trust come up. It ends with the defender's view: how Microsoft built a console meant to survive people with soldering irons.

      36C3 - Open Source is Insufficient to Solve Trust Problems in Hardware

      media.ccc.de · 13K views · 6 years ago

      bunnie's harder conclusion is that checking hardware destroys it, so even open designs leave a time-of-check/time-of-use gap, and he sketches what might narrow it.
