I don't believe so. If one of those states managed to seize a US nuclear weapon, that'd be evidence of such a failure. The specific case of protecting backdoor keys really comes down to keeping from getting physically stolen, which at least the US government should be perfectly capable of.

Mere assertions that they "should be perfectly capable" are just vacuous statements that don't mean anything. 1) We're not just talking about the US government that will have access to keys. 2) The US government has shown itself to be perfectly capable of losing secrets. I'm not saying, as you did, they "should be." I'm saying they have proved it. So have the governments of other countries. 3) We don't know how those countries got all the information they have. We may know where some of their information came from, but not all of it. 4) NSA is supposed to be our best and brightest at protecting secrets. Look what they did. 5) Some proposals for encryption backdoors allow for access by law enforcement at almost any level, down to local sheriff / police. They would probably stop just above mall cop, if they could. If you have a retort to just some of these points, unfortunately that doesn't fix the problem. You would have to be able to answer all of them. A leak only takes one weak point.

  >We're not just talking about the US government that will have access to keys. Well I doubt the $insert_country would want to share their keys with others. Why would they? It'd make far more sense to send in encrypted message and get decrypted message back. >The US government has shown itself to be perfectly capable of losing secrets. But not even remotely comparable secrets. We're essentially talking about a physical item here, not a secret you can lose without losing possession of that item. >Some proposals for encryption backdoors allow for access by law enforcement at almost any level, down to local sheriff / police This may present logistical challenges for handling decryption requests, but I don't see it as a huge issue for keeping the keys from leaking. Obviously I'm not actually advocating this, I just think that you're making some rather dishonest arguments here.

      How do you propose the keys would escape a HSM? You wouldn't keep this stuff connected to the network, so someone would have to get physical access to even attempt to attack it.

        lol!

        Do you even know what a HSM is? Did you consider their existence before initially commenting? If you do know what HSMs are, do you believe that they’re all useless? Idk where the “lol!” came from, we’re talking about extremely standard cryptographic key storage here.

        You are seriously not trolling? Google “weakest link” and re-read the thread. An HSM is not magic and does not fix all the problems.
        ryanlol 8y ago
        How would a government lose control of keys generated and stored within a offline HSM in a shielded room, without actually losing possession of that HSM? This is very obviously not unfeasible to implement in a secure manner. So far you've only given examples of secrets which are really easy to lose control of, this simply isn't one. I'm not trying to argue that this should be done, you claimed this can't be done which is obviously false
