    Phoronix: AMD, Google, Microsoft & NVIDIA Announce "Caliptra" Open-Source Root of Trust

    AMD, Google, Microsoft, and NVIDIA have used this week's OCP Global Summit to announce Caliptra as their open specification for a silicon Root-of-Trust (ROT) to be found with future CPUs / SoCs, GPUs, NICs, SSDs, and other hardware components.

    I could not care less whether Microsoft or Google are on board, but both Intel and Arm seem to be missing. Also curious is that although Nvidia is being mentioned here did Nvidia in fact not contribute to the specification and only AMD, Microsoft and Google are being listed on the document and its revision history.

      The name ROT will probably not age well.

        Another hardware backdoor?
        Every time I see the word "trust", "secure", whatever, I know something is fishy!

          I don't want it, I don't want to pay for it (die size).

              It's about time Analog TRNG was added as standard. How did we go this many decades without that being on every desktop?

              > notably absent from today's announcement is Intel.

              Intel couldn't figure out a way to make this insecure so they just decided the best insecurity they could add to their product is to not add this at all.

                How does this compare to https://opentitan.org/ ?

                  When I think of trust, oh yea, I think of Google, Microsoft & NVIDIA.

                    The user and not the hardware vendor should be able to decide which code runs on their devices. I especially won't trust Google here, which supports denying access to applications for users with rooted Android devices (Google SafetyNet a.k.a corporate Digital Restrictions Management).
