    Black Hat 2010
    Isn't that, like, ancient history?

    Are you suggesting that vulnerabilities haven't been addressed over the course of 3 years?

    To play devil's advocate -- How likely is it that TPM 2 addressed the flaws from 2010 and there has been no similar compromise since then?

      Philosophically speaking, I am one of those people who still believes in the concept of a personal computer.

      I also have a problem with a technological fix that can brick the computer due to an error or a cosmic ray flipping a bit. I'm told that's the number one source of "soft" errors these days.

      http://en.wikipedia.org/...

      Once the electronics industry had determined how to control package contaminants, it became clear that other causes were also at work. James F. Ziegler led a program of work at IBM which culminated in the publication of a number of papers (Ziegler and Lanford, 1979) demonstrating that cosmic rays also could cause soft errors. Indeed, in modern devices, cosmic rays may be the predominant cause. Although the primary particle of the cosmic ray does not generally reach the Earth's surface, it creates a shower of energetic secondary particles. At the Earth's surface approximately 95% of the particles capable of causing soft errors are energetic neutrons with the remainder composed of protons and pions.[2] IBM estimated in 1996 that one error per month per 256 MiB of ram was expected for a desktop computer.[3] This flux of energetic neutrons is typically referred to as "cosmic rays" in the soft error literature. Neutrons are uncharged and cannot disturb a circuit on their own, but undergo neutron capture by the nucleus of an atom in a chip. This process may result in the production of charged secondaries, such as alpha particles and oxygen nuclei, which can then cause soft errors.

      Others have simply gotten old. I prefer to think I've been tempered by time.

        has the ability to 'brick' a drive because of error.  Luckily there are various ways to backup the key securely.  You're over thinking this it, TPM at it's heart is a hardware encryption authentication module.

          TPM has already caused problems for people.

            the fear of a device bricking because of a flipped bit caused by cosmic rays.  That fear isn't the exclusive domain of devices which utilize TPM.  It's a problem with all whole drive encryption systems.

            On the upgrade issue, I also don't know why you're putting so much stock into literally one random person with a problem on the internet.  It sad that there exists this single person who 15 months ago lost data because of a bug in a product but those are the dangers in using a pre-release version of software.

            Here's basically what it boils down to, this is FUD.  You've overstated the problem.  There is one alleged instance in which a computer was damaged by Windows 8 and TPM and it's a very unique situation that included using a non stable, non release candidate O/S on a laptop that was suffering from a manufacturer error.

              if you think only one person has had this problem.

              computer was permanently bricked.  As in throw it away and buy another one (or have the entire motherboard replaced).  Let me repeat that, there is no way to wipe the entire system and restore from backups you have to buy a new computer.  How many whole drive encryption systems render the hardware permanently non-functional if there is a problem?

        that victory can't be suggested by noting one three-year-old salvo, sans mention of response nor follow up.
