4 SPEC - Spec not finalized
24 =======================================================================
29 NR - Work more on Paul's NRL research problem.
32 I * Email auto-responder
33 * teach gettor how to ask for (and attach) split files.
36 . With Mike's help, use Torflow to start doing monthly rudimentary
37 performance evaluations:
38 . Circuit throughput and latency
39 - Measure via Broadband and dialup
40 . Publish a report addressing key long-term metrics questions:
41 . What metrics should we present?
42 . What data are available for these metrics?
43 . What data are missing, and can collect them safely? Can we
45 . What systems are available to present this data?
47 E . Vidalia improvements
48 o Vidalia displays by-country user summary for bridge operators
49 ? - write a help page for vidalia, "what is this"
53 Section 0, items that didn't make it into the original roadmap:
55 0.1, installers and packaging
56 C . i18n for the msi bundle files
57 P . more consistent TBB builds
58 IC- get a buildbot up again. Have Linux and BSD build machines.
59 (Windows would be nice but realistically will come later.)
60 E - Get Tor to work properly on the iPhone.
62 3.1, performance work. [Section numbers in here are from performance.pdf]
63 - High-priority items from performance.pdf
64 RS - 1.2, new circuit window sizes. make the default package window lower.
65 R+ - 2.1, squeeze loud circuits
66 - Evaluate the code to see what stats we can keep about circuit use.
67 - Write proposals for various meddling. Look at the research papers
68 that Juliusz pointed us to. Ask our systems friends. Plan to put
69 a lot of the parameters in the consensus, so we can tune it with
70 short turnaround times.
71 E+ - 2.5, Change Vidalia's default exit policy to not click "other
72 protocols". Or choose not to. Think this through first.
73 R+ - 2.6, Tell users not to file-share.
74 - Put statement on the Tor front page
75 - Put statement on the download pages too
78 I - Implement time-to-notification (immediate, a day, a week)
79 I - Get a relay operator mailing list going, with a plan and supporting
81 R - Link to them from the Tor relay page
82 R - and the torrc.sample?
83 SM - 4.1, balance traffic better
84 - Steven and Mike should decide if we should do Steven's plan
85 (rejigger the bandwidth numbers at the authorities based on
86 Steven's algorithm), or Mike's plan (relay scanning to identify
87 the unbalanced relays and fix them on the fly), or both.
88 - Figure out how to actually modify bandwidths in the consensus. We
89 may need to change the consensus voting algorithm to decide what
90 bandwidth to advertise based on something other than median:
91 if 7 authorities provide bandwidths, and 2 are doing scanning,
92 then the 5 that aren't scanning will outvote any changes. Should
93 all 7 scan? Should only some vote? Extra points if it doesn't
94 change all the numbers every new consensus, so consensus diffing
96 ? - 4.5, Older entry guards are overloaded
97 - Pick a conservative timeout like a month, and implement.
98 M - 5.2, better timeouts for giving up on circuits/streams
99 - clients gather data about circuit timeouts, and then abandon
100 circuits that take more than a std dev above that.
102 4.1, IOCP / libevent / windows / tor
103 N - get it working for nick
104 N - put out a release so other people can start testing it.
105 N - both the libevent buffer abstraction, and the
106 tor-uses-libevent-buffer-abstraction. Unless we think that's
107 unreachable for this milestone?
109 4.2.1, risks from becoming a relay
110 S - Have a clear plan for how users who become relays will be safe,
111 and be confident that we can build this plan.
112 - evaluate all the various attacks that are made possible by relaying.
113 specifically, see "relaying-traffic attacks" in 6.6.
114 - identify and evaluate ways to make them not a big deal
115 - setting a low RelayBandwidth
116 - Nick Hopper's FC08 paper suggesting that we should do a modified
117 round-robin so we leak less about other circuits
118 - instructing clients to disable pings in their firewall, etc
119 - pick the promising ones, improve them so they're even better, and
120 spec them out so we know how to build them and how much effort is
121 involved in building them.
123 4.5, clients download less directory info
124 N * deploy proposal 158.
125 N - decide whether to do proposal 140. if so, construct an implementation
126 plan for how we'll do it. if not, explain why not.
128 5.1, Normalize TLS fingerprint
129 N o write a draft list of possible attacks for this section, with
130 estimates about difficulty of attack, difficulty of solution, etc
131 N - revisit the list and revise our plans as needed
132 NR- put up a blog post about the two contradictory conclusions: we can
133 discuss the theory of arms races, and our quandry, without revealing
134 any specific vulnerabilities. (or decide not to put up a blog post,
135 and explain why not.)
137 5.5, email autoresponder
138 I . maintenance and keeping it running
145 E - add breakpad support or similar for windows debugging
146 E o let vidalia change languages without needing a restart
147 E - Implement the status warning event interface started for the
148 phase one deliverables.
149 E - Work with Steve Tyree on building a Vidalia plugin API to enable
150 building Herdict and TBB plugins.
153 M - Steps toward automation
154 - Set up email list for results
155 - Map failure types to potential BadExit lines
156 M - Improve the ability of SoaT to mimic various real web browsers
157 - randomizing user agents and locale strings
158 - caching, XMLHTTPRequest, form posting, content sniffing
159 - Investigate ideas like running Chrome/xulrunner in parallel
161 - SSH, IMAPS, POPS, SMTPS
162 M - Add ability to geolocalize exit selection based on scanner location
163 - Use this to rescan dynamic urls filtered by the URL filter
165 6.4, Torbutton development
166 M - Resolve extension conflicts and other high priority bugs
167 M - Fix or hack around ugly firefox bugs, especially Timezone issue.
168 Definitely leaning towards "hack around" unless we see some
169 level of love from Mozilla.
170 M - Vidalia New Nym Integration
171 - Implement for Torbutton to pick up on Vidalia's NEWNYM and clear
172 cookies based on FoeBud's source
173 - Do this in such a way that we could adapt polipo to purge cache
174 if we were so inclined
175 M - Write up a summary of our options for dealing with the google
176 you-must-solve-a-captcha-to-search problem, and pick one as our
179 6.6, Evaluate new anonymity attacks
180 S - relaying-traffic attacks
181 - original murdoch-danezis attack
182 - nick hopper's latency measurement attack
183 - columbia bandwidth measurement attack
184 - christian grothoff's long-circuit attack
186 - website fingerprinting
188 7.1, Tor VM Research, analysis, and prototyping
189 C . Get a working package out, meaning other people are testing it.
191 7.2, Tor Browser Bundle
192 I - Port to one of OS X or Linux, and start the port to the other.
193 I . Make it the recommended Tor download on Windows
194 I - Make sure it's easy to un-brand TBB in case Firefox asks us to
195 I - Evaluate CCC's Freedom Stick
