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

Here's alengthy ars technica article on efforts to replace Tor with somethingmore secure. "As a result, these known weaknesses have promptedacademic research into how Tor could be strengthened or even replaced bysome new anonymity system. The priority for most researchers has been tofind better ways to prevent traffic analysis. While a new anonymity systemmight be equally vulnerable to adversaries running poisoned nodes, betterdefences against traffic analysis would make those compromised relays muchless useful and significantly raise the cost of de-anonymisingusers."
