Oh, come now. El Reg needs to talk to more experts than these two cadres who are operatives in the crypto-anarchist movement. Obviously *they* will tell you that it is "impossible" -- just like for years these same people told us that it was "impossible" to digitally protect copyright because anything can be copied or cracked -- and yet now tell us there is invincible code that can't allow law-enforcers *even with a warrant* to enter.
There's something deeply criminal and sinister here and I would expect El Reg, with its long and illustrious history of crying foul on all the copyleftist nonsense coming out of Silicon Valley, to cry foul on crypto-anarchy.
There are all kinds of ways this can be done starting with the obvious, the skeleton key that works on all phones which the hysterics keep telling us "can't" be done because Russians or Chinese or Al Qaeda will hack it.
That's funny, you said nothing could crack this code, and yet if you lock up the skeleton key really well, that can be hacked because...Internet. But we all live in an environment of massive hacking and people devise all kinds of systems every day, organic and mechanic, to cope to deter and at least mitigate the situation if not cure it.
The same approach can be taken to the skeleton key protection. Make a skeleton key that allows for changing or obfuscation or a range that hackers can't figure out, or a pattern they can't figure out.
Then there's two-factor keys that have been discussed which we're always told is "hard." Well, allowing criminals to roam free is hard, too, so work on it.
We're told by young Matt Apuzzo that in fact the feds can wiretap real-time phone calls. Oh? So if they can do that, why can't they also get into this black closed box?
The cryptos were allowed to win the first two rounds of the crypto wars -- Clipper Chip and PGP. They can't be allowed to win this one or we will live under the tyranny of anarchy -- which we increasingly do anyway because of Manning, Snowden, Anonymous, etc.
And they don't to win it in order for all of us to have privacy but with some capacity for law-enforcement in a democratic society to be able to control crime. Otherwise, we are handing over the Internet and all things digital -- and here comes the Internet of Things -- to people who under cover of privacy rights instigate crime, terrorism, and anarchy to destroy states. I'm serious.
