Tor Weekly News                                     September 11th, 2013

Welcome to the eleventh issue of Tor Weekly News, the weekly newsletter that
covers what is happening in the XXX Tor community.

Tor is out

On 5th September, Roger Dingledine announced the release of a new release candidate 
for Tor 0.2.4 series [XXX]. It comes with very handy feature in the current situation [XXX]
- prioritizing faster and safer circuit-level handshakes "NTor" over "TAP" used by
0.2.3 clients.

“Relays now process the new "NTor" circuit-level handshake requests with higher 
priority than the old "TAP" circuit-level handshake requests. We still process 
some TAP requests to not totally starve 0.2.3 clients when NTor becomes popular. 
A new consensus parameter "NumNTorsPerTAP" lets us tune the balance later if we 
need to. Implements ticket 9574 [XXX].”

Roger asks relay operators to consider upgrading to version due the huge 
circuit overload we see nowadays [XXX]. Upgrading to development branch is surprisingly
easy using this guide [XXX].

Help Desk Roundup
We had a number of emails this week asking about the recent stories in 
the New York Times, the Guardian, and Pro Publica regarding NSA's cryptographic 
capabilities. Some users asked whether there was a backdoor in Tor. Others asked 
if Tor's crypto was broken. 

There is absolutely no backdoor in Tor. We have been vocal in the past about how
tremendously irresponsible it would be to backdoor our users[xxx]. We also have
an FAQ entry explaining some ways we would fight back if anyone tried[xxx].

We do not have any more facts about NSA's cryptanalysis capabilities than have 
been published in newspapers. However it is the belief of many Tor developers 
that even considering these new developments, Tor's encryption is effective. 
Tor uses TLS for link encryption. If the TLS is good, an outside attacker can't 
even get to Tor's crypto. If the TLS is bad, good thing we have Tor's crypto. 

Breaking SSL/TLS could involve something besides cracking cryptographic 
primitives. For example an attack could be accomplished by finding some 
vulnerability in the way the https protocol is implemented, or by compromising 
the computers of Certificate Authorites to get their private keys. Or by legally 
coercing Certificate Authorities to hand over their private keys and shut up 
about it. I'm sure there are other ways it could be done as well. The math that 
makes encryption hard to break still stands. Tor's code is completely open source 
and has many eyes inspecting it. The encryption that Tor uses is summarized on the
FAQ page[xxx] and detailed in the Tor specification[xxx].
