Building a new Tor that can resist next-generation state surveillance (ars technica)

Here's a lengthy ars technica article on efforts to replace Tor with something more secure. "As a result, these known weaknesses have prompted academic research into how Tor could be strengthened or even replaced by some new anonymity system. The priority for most researchers has been to find better ways to prevent traffic analysis. While a new anonymity system might be equally vulnerable to adversaries running poisoned nodes, better defences against traffic analysis would make those compromised relays much less useful and significantly raise the cost of de-anonymising users."
