I see that Meta’s engineers are still busy and happy to build a dystopia in exchange of money. Damage is already done, they’ve shipped nearly working software to any creep and police officer that need little modification to actually work. I

That’s a self-defeating definition. Work that can be automated at no marginal cost is economically worthless. Edit for clarity: “worthless” as in “no value add”, its worth is only capital investment and energy input.

I spotted a few oddities in the reporting of these ‘secret papers’.[1] The only extract of the report the journalists show is, at the very least, misleading. They’re claiming that Fujitsu employees could do a type of requests which would (i

Still requires special hardware and authentication, AFAICT. Plus, you often have got length (hundreds of km) and connection constraints (e.g., only over fibre optic).

Quantum Key Distribution (QKD) requires special (expensive) hardware, so it really doesn’t solve the problem of key size. Moreover, QKD still requires an authenticated channel, so we’ll still need a quantum-resistant authentication scheme.

I dont disagree with this. I just want to highlight that to do this sort of sandboxing in any systematic manner, you’ll always need to go down at the system level. Because here we’re trying to sandbox the system using abstraction at the la

WDYT of WASM capability system? IMO, it would be a good contender for sandboxing dependencies. However, I haven’t tested it in practice.

You don’t even need unsafe to reproduce unsafe behaviour on Linux. You can just read and write to `/proc/self` and modify memory arbitrarily. If you have `std::fs`, then you have `unsafe`, then you’ve got everything. In general,

In theory, yes. In practice, TCBs are so big, that DRM solutions based on it are nearly meaningless for general purpose computers.

I’ve seen many widely deployed applications of TPM for security, never for DRM.

Thanks for the layman’s explanation, I didn’t realise something like that was even possible! What are some use cases for using it? Are they all crypto-currency related?

That’s "good things happen to (some) bad people. Rejoice!" Quite the opposite of what was said above. I don’t consider myself a Calvinist, so I don’t have skin in the game. However, sweeping statements like this prevent you from

Yes, please. I’m pretty sure Calvinism says that everybody is corrupted by sin (not just prisoners) and that everybody is in need of God’s grace. There’s certainly nothing about celebrating when something bad happens to somebody.

From a more security security research point-of-view, the paper “Bootstrapping Trust in Commodity Computers”[1] is a very good overview. Although it would necessitate a bit of an update for more recent developments with e.g. dm-verity etc.
