So I'm totally making stuff up here, and my interest in crypto has a hackish rather than academic flavor, but...
Couldn't we design a system that doesn't fall in this scenario, by using a constant-rate packet-blasting network that emits "background radiation" even if nothing is happening, and then filters out the good stuff via chaffing/winnowing [1]? This would clog the tubes like a torrent and run you a similar tab, but wouldn't it be 100% anonymous even in the face of such an adversary, while still being low-latency?

- sillysaurus2 13y agoYes, but Tor is already very slow, and it has a lot of resources behind it already. It would take a substantial amount of money to bootstrap your network. It'd be a worthy 1-10MM investment --- assuming you don't want any ROI on it.
- simcop2387 13y agoFreenet actually does this, though they aren't just sending random chaff, they'll actually use it to duplicate the data. It makes this particular attack impossible, but freenet has it's own potential issues. If you control all of someone's inputs and outputs you can still determine when they are using the system.
