RunCore Introduces Self-Destructable SSD

jones_supa writes "RunCore announces the global launch of its InVincible solid state drive, designed for mission-critical fields such as aerospace or military. The device improves upon a normal SSD by having two strategies for the drive to quickly render itself blank. First method goes through the disk, overwriting all data with garbage. Second one is less discreet and lets the smoke out of the circuitry by driving overcurrent to the NAND chips. Both ways can be ignited with a single push of a button, allowing James Bond -style rapid response to the situation on the field."

      I suspect that(aside from simply being relatively cheap to implement, and having some expected sales based on the 'cool' factor alone) the real purpose of any system purporting to substitute for, or complement, disk encryption is to deal with weaknesses unrelated to the cryptographic system itself.

      As best we know, contemporary crypto systems with keys of reasonable length are not breakable in any useful sense. However, since humans who can store keys of reasonable length are vanishingly rare, most such systems must weaken themselves by storing a good chunk of the key somewhere where it can be recovered(on the device, with a password/passphrase, embedded in a smartcard/fob that is merely expensive and inconvenient to crack and extract, etc.)

      If you just hand somebody an AES blob and tell them to come up with the correct 256 bits for themselves, they are SOL. If somebody's HDD is encrypted such that it can be unlocked with a password it is quite likely that dictionary-aided brute force will be enough. If the key is on a smartcard IC it might not be cheap to pull the key; but they don't produce those things in volume for a few bucks a chip, at most, by using all available security features...

      Considering the (mostly) invincible state of good encryption, this seems unnecessary. Sure, it is a fun idea, but not a practical one.

      No encryption is invincible. Especially 5 years from now... Computing power has advanced to the point where you can just brute force "invincible encryption" from a few years back...

      A few have pointed out that the keys are too large to brute force. I figure you out to know why that is: http://everything2.com/title/Thermodynamics+limits+on+cryptanalysis

      That is a good little write up on the subject. Short, sweet, and easy to follow. It demonstrates that non quantum 256 bit keys are safe from brute force attacks for... ever.

      Two wrenches (one esoteric, one practical): Reversable Computation and Quantum Computers.

      First the "practical" one, Quantum Computers. The algorithm for searching an unsorted database for a key is Grover's Algorithm. This gives a speed up of O(N1/2) and a space complexity of O(log N). For a 256 bit key this gives a time complexity of 2**128 and a space complexity of 78. Now, that time complexity will kill you. Move to a 512 bit key and we are back to 2**256 time complexity (jsut like in the linked article). The space complexity goes to 155. It might not seem like a big deal, but adding another qbit to a quantum machine isn't trivial. In fact it is properly hard, and gets harder for every extra qbit. also that space complexity is a multiplier, not a count. you need log N * or something along that scale (Big O notation demonstrates the rate of growth as things go to infinity so small problems can be dominated by other factors till they "scale up"). Obviously even quantum computation isn't going to help crack a 256 bit key and a 512 bit key will restore the same level of security even IF they could be built large enough and numerous enough and fast enough for the 256 bit version (LOTS OF IFS and with an easy out. As pointed out increasing an encryption key's size is relatively trivial)

      Now for the one that caused me some trouble, Reversable Computing. Fancy way of saying that the computation is reversable with no energy expended after being performed and reversed (actually arbitrarily little energy appraoching zero as closely as you care to come... kinda. Physical devices pose practical problems, but let us se that asside for a moment). This is a theory, and a good one. The problem is that you need to drive through all of the states. Let us assume that a computation takes one plank time on our perfect reversable computer (this is impossible, of course. It would be far higher even with a "perfect" device, but this is a lower bound given to us by nature). You need 1.4 * 10**16 time the current age of the universe (1.979 * 10**26 years) worth of computer time to go through all the states. Average is half that to find the correct key. Now you'll want to parallelize this computer to get to that (wholly impractical) time faster. How many can you build? How large are they? I'll leave it as an exerccise to the reader to determine how many you might be able to construct before they collapsed into a black hole. Also: 1 plank time is a few dozens of orders of magnitude smaller than any computation done with matter can achieve. It takes 4.48*10**20 plank times for a photon to pass an electron (if wolfram alpha is being nice to me, that is). Scale your time to be, say, the same as the time it takes a photon to cross your theoretical perfect reversable computer and then work out how many you need to complete the cracking of the key within a reasonable time. You'll get a black hole or incredible distances beyond the mortal ken.

      Conclusion: Brute forcing any appreciably sized cryptographic key (512 bit or greater) will never, ever be possible no matter what happens with technology so long as computers are made of matter and compute in space. Period.
      256 bit keys will remain equally unchallenged until we can create and power quantum computers the size of grains of sand trilions at a time.

      Secure erase on an SSD is nearly instantaneous.Yes, having to erase a block before writing it can limit your IOPS when you have to WAIT for it to be erased, but when you're issuing the erase command in parallel to every NAND chip/block, it takes virtually no time at all (about a second last time I tried). The ideal solution would seem to be a secure erase followed by overvolting. The overwriting part serves no purpose on a NAND-based device.

  22. fake video by Inigo+Montoya · · Score: 1

    nice fake video.. photoshopped nand chips. I've never seen a chip destroy itself in that manner, as they've shown.

    The chip itself is always in the dead center of the carrier, nand flash is bigger than most chips, but still centered in the carrier package. usually the chips overheat, expand the air in the packaging and blow a single crack or blow the top off. not multiple swirly cracks like they've shown for the oohhh..awwww... effect.

    And the silkscreen is distorted and swirled too. That just won't happen and it's a smoking gun. Would you trust your data with a company from China that is obviously faking its advertising in such a despicable way?

    I am sure the last thing you want to rely on in a crisis is someone fumbling with a RAID array full of SSDs. Far better to encrypt the data. Power off the unit, you loose the key and all you have is a random collection of 1 and 0.

  31. The FBI would like ALL SSD drives banned by grantspassalan · · Score: 1

    SSD's are forensically very much harder to deal with. When the computer user erases such a drive, the control data is re-zeroed and the wear leveling controller in the drive starts rearranging data among the various memory chips as soon as the drive is powered up, whether in a computer or otherwise. For this reason forensic data on an SSD drive cannot be relied upon if it can even be recovered at all. The data is randomly spread out among all the chips in the drive, which makes it very hard to reassemble, even if the controller did not immediately start messing it up, as soon as the drive was given a new erase command from the OS.
