And in part because Stefan’s a scientist and wouldn’t say something he couldn’t back with evidence. Whereas, on the other hand, Matt’s backdoor proposals have been published as opinion pieces in Lawfare. 2/2

Read both pieces and come back to me. Seriously.

I’ve read both (though Tait’s I read less carefully because I am like you a bit dismissive of secret escrow). I get why you’re more comfortable with Savage’s Lawful Access paper, but suspect that’s because it’s just less conclusory and more exploratory than Tait’s.

Stefan’s paper addresses the fact that even with basic key splitting, those systems are vulnerable to compromise. And goes to enormous lengths to try to address this through physical means.

I mean, in reality, it’s Apple’s enormous and talented security team that’s going to do the real design work on a mandated lawful access feature; they’re probably not really going to shoplift it out of papers Matt and Stefan write.

Right. And where is Apple’s vaunted security team when it comes to securing the damn SEP against Cellebrite and GrayKey?

I don’t think “customers are screwed no matter what the Senate decides” is the rhetorical kill-shot you’re hoping for in this debate. :)

The point I was going for is that “the very best people in the world” can’t solve this problem, which is only a data point, but a *very important* datapoint indicating that this problem is much harder than it looks.

I don't find this helpful. First, "this problem" hides a multitude of sins. You know it's not one problem and there isn't even agreement on what the problems are. Second, there has been little effort (at least out of academia) to try to solve any version of "this problem".

I’m working on a paper on this subject. For what that’s worth. The reason academia has hit a wall is that the problem has largely been reduced one of three old problems. Key escrow. Secure hardware. Secure software.

We basically know how to do key escrow. We (meaning the world’s leading manufacturers and experts) are still struggling with secure hardware and secure software. As the SEP fiasco indicates.

When academia or industry gives us perfectly secure hardware and software, the problem will be solved. Nobody will need to send new papers on this specific application. Until those are solved, we either need to stop doing this —— or we need fundamentally new ideas.
