862)     The Tor code is more than 10 years old in places, and we haven't always had

863)     enough time or wisdom to write things as well as we could have.  Our unit
864)     test coverage is shamefully low, and the dependency graph of our modules is
865)     shamefully convoluted . We could use refactoring and unit tests!  Please
866)     look through the Tor source code and look for ugly or tricky code or
867)     dependencies -- the uglier and trickier the better -- and think about how

1017) The feature should also add support for including only packet capture data that

1024) This can probably be implemented by setting up a tun/tap device and routing all

1041)     <p>
1042) Right now, our unit test coverage with the tests we ship is around 30%
1043) -- only 30% of the executable lines in our source are reached by the
1044) unit tests.  Improving this test coverage could make Tor development
1045) much more reliable.
1046)     </p>
1047) 
1048)     <p>
1049) So we need better unit tests, and we need better integration tests too.

1051) 
1052)     <p>

1053) Improving unit tests would involve refactoring functions to be more

1054) testable, and writing a bunch of unit tests.
1055)     </p>
1056) 
1057)     <p>

1058) Improving integration tests would involve refactoring and improving

1059) the "chutney" program that launches a test tor network, and writing a
1060) bunch of tests to see what works and what doesn't work on such a
1061) network.  It could also involve writing tests using the library "<a
1062) href="https://stem.torproject.org/">stem</a>" to script individual clients on a
1063) Chutney network.
1064)     </p>
1065) 
1066)     <p>
1067) To get a feel for how testing works in Tor today, download Tor and
1068) Chutney, and make sure you can build Tor and use Chutney.  See how the
1069) unit tests work by skimming some of the test code in the src/test
1070) subdirectory.  Try computing test coverage (according to the
1071) instructions in the doc/HACKING file.
1072)     </p>
1073) 
1074)     <p>
1075) Also, have a look at the one current integration test that works on
1076) chutney today: it is a shell script distributed with Tor as
1077) src/test/test-tor-network.sh .  We probably don't want to have all of
1078) our integration tests be written as shell scripts, but it's interesting
1079) to see how one works.
1080)     </p>
1081) 
1082)     <p>
1083) If working on designs for an improved or refactored Chutney, watch out for <a
1084) href="http://www.joelonsoftware.com/articles/fog0000000018.html">"archicture
1085) astronautics"</a>: while it's important that we have a well-designed and
1086) maintainable Chutney architecture, it wouldn't be very useful if a good
1087) architecture were the <em>only</em> outcome here: we need tests too.
1088)     </p>
1089) 
1090)     <p>
1091) As part of the application process, please contribute a patch that makes
1092) a non-trivial improvement to chutney, and/or include a new test for some
1093) interesting Tor function. (Please pick a function that isn't completely
1094) easy to test.)

1105)     <br><br>

1106)     <p>
1107) Right now, if you run a busy Tor server on a multicore computer, most of
1108) the cores are mostly unused.  We have a "cpuworker" mechanism to move
1109) expensive computations into worker threads, but that mechanism is
1110) currently only used for a small fraction of our cryptography.  Moving
1111) more work into the worker threads could improve performance immensely.
1112)     </p>
1113) 
1114)     <p>
1115) So it would be great to parallelize our cryptography more in order to
1116) better handle more cores.  See

1130) Completing the implementation of ticket #7572 --which would move our
1131) circuit crypto onto separate threads-- could be a good summer project.
1132) Alternatively, moving all of the signature generation and verification
1133) code onto the cpuworkers could be fun.  In either case, you will have
1134) some important architectural decisions to make about how to minimize
1135) shared data between the main thread and the workers, how to avoid
1136) race conditions between them, and how to test it all to make sure it has

1192) Right now, you can only use Tor's DNS support to look up IPv4 and IPv6
1193) addresses, and to fetch PTR records.  But DNS can do so much more!

1202) 
1203)     <p>
1204) To see how Tor implements its existing DNS lookups, start by tracing the
1205) the connection_exit_begin_resolve() function in src/or/connection_edge.c ,
1206) and see how we pass these requests downwards through src/or/dns.c to the

1227) The Tor Project makes use of the Python tool <a
1228) href="https://gitweb.torproject.org/user/phw/exitmap.git/">Exitmap</a> to
1229) systematically scan for malicious and misbehaving exit relays.  Once such a
1230) relay is found, it is assigned the BadExit flag which prevents clients from
1231) selecting the relay as last hop in their circuit.
1232)     </p>
1233) 
1234)     <p>
1235) Exitmap supports scanning modules which implement a specific scan over
1236) exit relays.  Examples are the DNS module which checks for DNS poisoning
1237) or the patching check module which looks out for tampered file
1238) downloads.
1239)     </p>
1240) 
1241)     <p>
1242) This project is meant to extend exitmap in several ways.  First, it
1243) should be made fully autonomous.  That means that exitmap should be able
1244) to run in the background, periodically fetch new relay descriptors, and
1245) have a smart algorithm which keeps scanning all exit relays
1246) periodically.  Second, exitmap should be able to emulate some user
1247) interaction and dynamically "explore" the web in order to detect
1248) tampering.  Third, unit tests should be added for existing and new code
1249) in order to make the code base more robust.

1283)     </p>
1284) 
1285)     <ul>
1286)       <li>Bring back the <a href="https://www.atagar.com/arm/images/screenshot_interpretor_full.png">interpreter panel</a>. This panel was dropped when refactoring Nyx, but it would be a neat component to bring back. You can <a href="https://gitweb.torproject.org/nyx.git/tree/src/cli/interpretorPanel.py?h=release">find old code for it in the history</a> and Stem (the library backing Nyx) has a much improved <a href="https://stem.torproject.org/tutorials/down_the_rabbit_hole.html">variant of this we can leverage</a>. This task would involve writing the curses code around Stem's interpreter functions.</li>
1287)       <li>Windows support. Like most curses applications Nyx doesn't run natively on Windows. We've had dozens of users request this and <a href="https://trac.torproject.org/projects/tor/wiki/doc/arm#Windows">it should be possible</a>. This would involve supporting PDCurses and expanding Stem to be able to query the cpu/memory usage of the tor process.</li>
1288)       <li>Unit testing! Nyx has <a href="https://gitweb.torproject.org/nyx.git/tree/test">started adding tests</a> but it's still very minimal. Achieving any substantial code coverage will require us to figure out how to unit test curses components.</li>
1289)       <li>Onionoo provides additional relay information that could enrich our connection panel such as geoip and rdns. Trick is that at present we can only query it on a per-relay basis which would leak our connections (no-go for security). However, if we could get information about all relays in bulk it would sidestep this. For some old thoughts on this see <a href="https://trac.torproject.org/projects/tor/wiki/doc/arm#CircuitDetails">here</a>.</li>

1300)     <b>Implement and Integrate CONIKS for Tor Messenger</b>
1301)     <br>

1302)     Language: <i>C, JavaScript</i>

1303)     <br>
1304)     Likely Mentors: <i>Marcela, Arlo (arlolra)</i>

1306)     <p>
1307) CONIKS is an end-user key management and verification system for end-to-end
1308) secure communication services, which improves upon existing key management
1309) systems by providing both strong security and better usability using a model
1310) called key transparency. CONIKS does this by requiring providers to manage
1311) tamper-evident, publicly-auditable key directories, which contain mappings from
1312) usernames to public keys, on behalf of their users. This design makes it easier
1313) for users (both "default" users and power users) to establish trust since they
1314) don't have to worry about or even see keys, but users also don't have to
1315) trust the provider to be well-behaved because the CONIKS client can run as
1316) part of the secure messaging app and automatically check that the service
1317) provider doesn’t map spurious keys to their users' usernames, and it can
1318) verify that observed name-to-key mappings are consistent with what other
1319) clients in the system are seeing. Unlike existing key transparency solutions,
1320) CONIKS also provides strong privacy guarantees by employing cryptographic
1321) primitives for robust data obfuscation.
1322)     </p>
1323) 
1324)     <p>
1325) The CONIKS system design, protocols, and proof-of-concept are described in
1326) great detail in the <a
1327) href="https://www.usenix.org/system/files/conference/usenixsecurity15/sec15-paper-melara.pdf">CONIKS
1328) research paper</a>, and basic reference implementations of a CONIKS key server
1329) and a CONIKS client are avialable on <a
1330) href="https://github.com/coniks-sys/coniks-ref-implementation">Github</a>.
1331)     </p>
1332) 
1333)     <p>
1334) This project has two main components: (1) designing and implementing a CONIKS
1335) key server tailored to Tor Messenger users, and (2) building a CONIKS client
1336) which integrates with the Tor Messenger client. One challenge the applicant
1337) will face is ensuring that the key server design is efficient and scalable for
1338) large volumes of users, concurrent traffic and guarantees this scalability even
1339) as Tor Messenger's user base grows. On the client side, the main challenges
1340) will be to focus on space efficiency as well as minimizing computational
1341) overhead when implementing the CONIKS consistency checks, and determining how
1342) to best communicate CONIKS consistency check results to users in the UI. Since
1343) Tor Messenger does not hand out online identities per se, as most online
1344) communication services do (like, say, Twitter, in which each user has a unique
1345) handle), the CONIKS key server for Tor Messenger will have to map usernames
1346) from third-party communication services to the encryption keys used in Tor
1347) Messenger. One additional important challenge that the applicant will have to
1348) help address is ensuring that each such third-party username remains unique in
1349) the Tor Messenger space and that such external, third-party identities are
1350) indeed controlled by the expected user of that third-party communication
1351) service.
1352)     </p>
1353) 
1354)     <p>
1355) Some design and implementation questions have been discussed in <a
1356) href="https://trac.torproject.org/projects/tor/ticket/17961">Ticket #17961</a>.
1357)     </p>
1358) 
1359)     <p>
1360) The applicant should have some familiarity with well-known crypto primitives
1361) and algorithms, as well as have a basic understanding of the key transparency
1362) model. Client side integration will require some basic use of JavaScript.
1363) Consider submitting a patch for <a
1364) href="https://github.com/arlolra/ctypes-otr/issues">one of the open key
1365) verification issues</a> as part of the application process.

1403)     <li>Tor relays don't work well on Windows XP. On
1404)     Windows, Tor uses the standard <tt>select()</tt> system
1405)     call, which uses space in the non-page pool. This means
1406)     that a medium sized Tor relay will empty the non-page pool, <a

1407)     href="<wiki>doc/WindowsBufferProblems">causing

1408)     havoc and system crashes</a>. We should probably be using overlapped IO
1409)     instead. One solution would be to teach <a
1410)     href="http://www.monkey.org/~provos/libevent/">libevent</a> how to use
1411)     overlapped IO rather than select() on Windows, and then adapt Tor to
1412)     the new libevent interface. Christian King made a
1413)     <a href="https://svn.torproject.org/svn/libevent-urz/trunk/">good
1414)     start</a> on this in the summer of 2007.</li>

1415) 

1416)     <li>We need a flexible simulator framework for studying end-to-end
1417)     traffic confirmation attacks. Many researchers have whipped up ad hoc
1418)     simulators to support their intuition either that the attacks work
1419)     really well or that some defense works great. Can we build a simulator
1420)     that's clearly documented and open enough that everybody knows it's
1421)     giving a reasonable answer? This will spur a lot of new research.
1422)     See the entry <a href="#Research">below</a> on confirmation attacks for
1423)     details on the research side of this task &mdash; who knows, when it's
1424)     done maybe you can help write a paper or three also.</li>

1425) 

1426)     <li>Tor 0.1.1.x and later include support for hardware crypto
1427)     accelerators via OpenSSL. It has been lightly tested and is
1428)     possibly very buggy.  We're looking for more rigorous testing,

1429)     performance analysis, and optimally, code fixes to OpenSSL and

1430)     Tor if needed.</li>

1431) 

1432)     <li>Write a <a
1433)     href="https://secure.wikimedia.org/wikipedia/en/wiki/Fuzz_testing">fuzzer</a>
1434)     for Tor to discover security vulnerabilities. Determine if there
1435)     are good fuzzing frameworks out there for what we want. Win fame by

1436)     getting credit when we put out a new release because of you!</li>

1437) 

1438)     <li>Tor uses TCP for transport and TLS for link
1439)     encryption. This is nice and simple, but it means all cells
1440)     on a link are delayed when a single packet gets dropped, and
1441)     it means we can only reasonably support TCP streams. We have a <a

1442)     href="<page docs/faq>#TransportIPnotTCP">list

1443)     of reasons why we haven't shifted to UDP transport</a>, but it would
1444)     be great to see that list get shorter. We also have a proposed <a

1445)     href="<specblob>proposals/100-tor-spec-udp.txt">specification

1446)     for Tor and
1447)     UDP</a> &mdash; please let us know what's wrong with it.</li>

1448) 

1449)     <li>We're not that far from having IPv6 support for destination addresses
1450)     (at exit nodes). If you care strongly about IPv6, that's probably the
1451)     first place to start.</li>

1452) 

1453)     <li>We need a way to generate the website diagrams (for example, the "How
1454)     Tor Works" pictures on the <a href="<page about/overview>">overview page</a>
1455)     from source, so we can translate them as UTF-8 text rather than edit
1456)     them by hand with Gimp. We might want to
1457)     integrate this as an wml file so translations are easy and images are
1458)     generated in multiple languages whenever we build the website.</li>

1466)     <li>
1467)     Another anti-censorship project is to try to make Tor
1468)     more scanning-resistant.  Right now, an adversary can identify <a

1469)     href="<specblob>proposals/125-bridges.txt">Tor bridges</a>

1470)     just by trying to connect to them, following the Tor protocol,
1471)     and seeing if they respond.  To solve this, bridges could <a
1472)     href="<svnprojects>design-paper/blocking.html#tth_sEc9.3">act like
1473)     webservers</a> (HTTP or HTTPS) when contacted by port-scanning tools,
1474)     and not act like bridges until the user provides a bridge-specific key.

1484)     <li>The "end-to-end traffic confirmation attack":
1485)     by watching traffic at Alice and at Bob, we can <a
1486)     href="http://freehaven.net/anonbib/#danezis:pet2004">compare
1487)     traffic signatures and become convinced that we're watching the same
1488)     stream</a>. So far Tor accepts this as a fact of life and assumes this
1489)     attack is trivial in all cases. First of all, is that actually true? How
1490)     much traffic of what sort of distribution is needed before the adversary
1491)     is confident he has won? Are there scenarios (e.g. not transmitting much)
1492)     that slow down the attack? Do some traffic padding or traffic shaping
1493)     schemes work better than others?</li>
1494)     <li>A related question is: Does running a relay/bridge provide additional
1495)     protection against these timing attacks? Can an external adversary that can't
1496)     see inside TLS links still recognize individual streams reliably?
1497)     Does the amount of traffic carried degrade this ability any? What if the
1498)     client-relay deliberately delayed upstream relayed traffic to create a queue
1499)     that could be used to mimic timings of client downstream traffic to make it
1500)     look like it was also relayed? This same queue could also be used for masking
1501)     timings in client upstream traffic with the techniques from <a
1502)     href="http://www.freehaven.net/anonbib/#ShWa-Timing06">adaptive padding</a>,
1503)     but without the need for additional traffic. Would such an interleaving of
1504)     client upstream traffic obscure timings for external adversaries? Would the
1505)     strategies need to be adjusted for asymmetric links? For example, on
1506)     asymmetric links, is it actually possible to differentiate client traffic from
1507)     natural bursts due to their asymmetric capacity? Or is it easier than
1508)     symmetric links for some other reason?</li>
1509)     <li>Repeat Murdoch and Danezis's <a
1510)     href="http://www.cl.cam.ac.uk/~sjm217/projects/anon/#torta">attack from
1511)     Oakland 05</a> on the current Tor network. See if you can learn why it
1512)     works well on some nodes and not well on others. (My theory is that the
1513)     fast nodes with spare capacity resist the attack better.) If that's true,
1514)     then experiment with the RelayBandwidthRate and RelayBandwidthBurst
1515)     options to run a relay that is used as a client while relaying the
1516)     attacker's traffic: as we crank down the RelayBandwidthRate, does the
1517)     attack get harder? What's the right ratio of RelayBandwidthRate to
1518)     actually capacity? Or is it a ratio at all? While we're at it, does a
1519)     much larger set of candidate relays increase the false positive rate
1520)     or other complexity for the attack? (The Tor network is now almost two
1521)     orders of magnitude larger than it was when they wrote their paper.) Be
1522)     sure to read <a href="http://freehaven.net/anonbib/#clog-the-queue">Don't
1523)     Clog the Queue</a> too.</li>
1524)     <li>The "routing zones attack": most of the literature thinks of
1525)     the network path between Alice and her entry node (and between the
1526)     exit node and Bob) as a single link on some graph. In practice,
1527)     though, the path traverses many autonomous systems (ASes), and <a
1528)     href="http://freehaven.net/anonbib/#feamster:wpes2004">it's not uncommon
1529)     that the same AS appears on both the entry path and the exit path</a>.
1530)     Unfortunately, to accurately predict whether a given Alice, entry,
1531)     exit, Bob quad will be dangerous, we need to download an entire Internet
1532)     routing zone and perform expensive operations on it. Are there practical
1533)     approximations, such as avoiding IP addresses in the same /8 network?</li>
1534)     <li>Other research questions regarding geographic diversity consider
1535)     the tradeoff between choosing an efficient circuit and choosing a random
1536)     circuit. Look at Stephen Rollyson's <a
1537)     href="http://swiki.cc.gatech.edu:8080/ugResearch/uploads/7/ImprovingTor.pdf">position
1538)     paper</a> on how to discard particularly slow choices without hurting
1539)     anonymity "too much". This line of reasoning needs more work and more
1540)     thinking, but it looks very promising.</li>
1541)     <li>Tor doesn't work very well when relays have asymmetric bandwidth
1542)     (e.g. cable or DSL). Because Tor has separate TCP connections between
1543)     each hop, if the incoming bytes are arriving just fine and the outgoing
1544)     bytes are all getting dropped on the floor, the TCP push-back mechanisms
1545)     don't really transmit this information back to the incoming streams.
1546)     Perhaps Tor should detect when it's dropping a lot of outgoing packets,
1547)     and rate-limit incoming streams to regulate this itself? I can imagine
1548)     a build-up and drop-off scheme where we pick a conservative rate-limit,
1549)     slowly increase it until we get lost packets, back off, repeat. We
1550)     need somebody who's good with networks to simulate this and help design
1551)     solutions; and/or we need to understand the extent of the performance
1552)     degradation, and use this as motivation to reconsider UDP transport.</li>
1553)     <li>A related topic is congestion control. Is our
1554)     current design sufficient once we have heavy use? Maybe
1555)     we should experiment with variable-sized windows rather
1556)     than fixed-size windows? That seemed to go well in an <a

1557)     href="http://www.psc.edu/index.php/hpn-ssh/638">ssh

1558)     throughput experiment</a>. We'll need to measure and tweak, and maybe
1559)     overhaul if the results are good.</li>
1560)     <li>Our censorship-resistance goals include preventing
1561)     an attacker who's looking at Tor traffic on the wire from <a
1562)     href="<svnprojects>design-paper/blocking.html#sec:network-fingerprint">distinguishing
1563)     it from normal SSL traffic</a>. Obviously we can't achieve perfect
1564)     steganography and still remain usable, but for a first step we'd like to
1565)     block any attacks that can win by observing only a few packets. One of
1566)     the remaining attacks we haven't examined much is that Tor cells are 512
1567)     bytes, so the traffic on the wire may well be a multiple of 512 bytes.
1568)     How much does the batching and overhead in TLS records blur this on the
1569)     wire? Do different buffer flushing strategies in Tor affect this? Could
1570)     a bit of padding help a lot, or is this an attack we must accept?</li>
1571)     <li>Tor circuits are built one hop at a time, so in theory we have the
1572)     ability to make some streams exit from the second hop, some from the
1573)     third, and so on. This seems nice because it breaks up the set of exiting
1574)     streams that a given relay can see. But if we want each stream to be safe,
1575)     the "shortest" path should be at least 3 hops long by our current logic, so
1576)     the rest will be even longer. We need to examine this performance / security
1577)     tradeoff.</li>
1578)     <li>It's not that hard to DoS Tor relays or directory authorities. Are client
1579)     puzzles the right answer? What other practical approaches are there? Bonus
1580)     if they're backward-compatible with the current Tor protocol.</li>
1581)     <li>Programs like <a

1582)     href="<page docs/torbutton/index>">Torbutton</a> aim to hide

1583)     your browser's UserAgent string by replacing it with a uniform answer for
1584)     every Tor user. That way the attacker can't splinter Tor's anonymity set
1585)     by looking at that header. It tries to pick a string that is commonly used
1586)     by non-Tor users too, so it doesn't stand out. Question one: how badly
1587)     do we hurt ourselves by periodically updating the version of Firefox
1588)     that Torbutton claims to be? If we update it too often, we splinter the
1589)     anonymity sets ourselves. If we don't update it often enough, then all the
1590)     Tor users stand out because they claim to be running a quite old version
1591)     of Firefox. The answer here probably depends on the Firefox versions seen
1592)     in the wild. Question two: periodically people ask us to cycle through N
1593)     UserAgent strings rather than stick with one. Does this approach help,
1594)     hurt, or not matter? Consider: cookies and recognizing Torbutton users
1595)     by their rotating UserAgents; malicious websites who only attack certain
1596)     browsers; and whether the answers to question one impact this answer.

1598)     <li>How many bridge relays do you need to know to maintain
1599)     reachability? We should measure the churn in our bridges. If there is
1600)     lots of churn, are there ways to keep bridge users more likely to stay
1601)     connected?
