EFF Promotes Freenet-like System Tor

An anonymous reader writes "The Electronic Frontier Foundation (EFF) just announced that it has become a financial sponsor of Tor, an open-source project to help people 'engage in anonymous communication online.' It sounds like a simpler version of Freenet, e.g. 'a network-within-a-network that protects communication from ... traffic analysis.' Like Freenet, the source-code is freely available and binaries exist for Windows, Linux, etc." Read on for more details.

The submitter continues "It also allows you to install Tor-aware apps, such as an HTTP proxy (for private browsing), or maybe private P2P? Unlike Freenet, it doesn't use massive encryption (as far as I can tell) and relies more on something called onion routing to randomly bounce requests between other Tor proxies, thus obfuscating the IP of the original client. So it allows you to browse regular Internet sites! Maybe it should be considered more of an 'open-source' Anonymizer? But I don't know if it's actually Open Source - you can download the source (and compile it yourself) but I don't know if the developers are letting anyone else touch their code. They are, however, looking for contributors and other forms of help. And, finally, they're hoping people will start running Tor servers!" It's open source, however contributions are handled.

  4. Solutions are simple. by robyannetta · · Score: 2, Interesting
    Disclaimer: IANAL!

    I, for one, do not use peer-to-peer file sharing for any reason. However the answer to secure peer-to-peer file sharing is so simple it's right in front of our noses.

    First, encrypt the file you want to send with GPG, make the decrypting password "1" or "A" or something that simple. If "any one else" decrypts the file and prosecutes you for it, you can get off by using the DMCA. That's right, the DMCA works for people too.

    Under the DMCA, the sender and receiver are the only two authorized to decrypt that file. If "any one else" decrypts it, even though they know the password, they are guilty of violating the DMCA. Now, from what I understand about the law, without a warrant to decrypt your encrypted file, it's not admissable in court because a law was broken to retrieve the file contents. No court likes "bad" cops, it's bad PR for judges.

    Current peer-to-peer technologies that are wide open are sufficient to carry "secure" information. Expending the extra energy to encrypt the file before it's sent is the problem. People need to stop being lazy.

    "If technology is plausible, we acheive it. Now pull the lever and 'beer me'."

  6. not cost effective to track and sue for RIAA et al by Cryofan · · Score: 2, Interesting

    I wonder if this could somehow be a case where it is not cost effective for RIAA/MPAA to track down the sharer of a particular file? I mean, they could do track down at least ONE file-sharer and then sue that person. But is just one person being sued serve as a sufficient deterrent to stop many filesharers?

    Right now, there are hundreds or even thousands of file sharers being sued (or being threatened, or getting letters etc). That threat serves as a real deterrent. But if it were too costly for them to detect hundreds of file sharers, the threat posed may not deter many people from sharing files. So, if so, then Tor could be a real plus for file sharers.

  9. Onion Routing != FreeNet by pridkett · · Score: 5, Interesting

    Just a quick FYI, TOR is an onion routing system, meaning that the data is passed between TOR proxies until it reaches it's destination. This means that eventually you still need to fetch the data from a server, which means that the server can still be put under attack or taken down.

    FreeNet is much more robust as you inject content and then it is stored in many nodes. Thus, it can't be taken down. Furthemore, in FreeNet different parts of the data are obtained from different sources, preventing more work that could be done with traffic analysis.

    To say that TOR is like FreeNet is to seriously discount the features of FreeNet. TOR is a system for running Onion proxies. FreeNet is a completely anonymized hosting and content distribution system.

    * anyway, if you work for a big governement agency you have the resources to treat these sorts of networks like a big black box and link up the endpoints.

The first message has to find it's way, but after that, each router peels the label (L in MPLS), routes it to that hop, and therefore routhing is very fast after the connection is established. What I don't understand is, the first hop has to know your requesting a www.yahoo.com page or it wouldn't know where to send your message.

Adult porn is one thing... you can at least make the argument that they're consenting adults just making a living... child porn is simply vile... it's sexual exploitation of someone too weak to fight, and mentally unable to understand and/or consent.

It's my job, literally, to take care of children who have been either physically abused, sexually abused, or both. Those kids are often brought straight to the ER, where Children's Services and I try to pick up the pieces. Maybe I'm too close to the issue, because it's simply visceral for me; I cannot stand the thought of aiding and abetting those kinds of acts, or encouraging the slime who get their jollies from that kind of thing.

      their scales balance a little differently than mine.

      I don't have a problem with Freenet because

      a) Freenet doesn't actually cache child porn on your drive. It may cache fragments of binary data which, if pieced together with other fragments from other sources and decoded a certain way, could be interpreted as something illegal. But that's a far cry from actually putting pictures or video on your disk.

      b) If someone looks at child porn from Freenet, no child is harmed. Since it's on Freenet, not only has the producer not been paid, he has no way to know that anyone has even seen it. Obviously the act of producing porn can harm children, but I can't think of any reason that anonymously viewing it with Freenet would lead to any further harm. So it's pretty much a victimless crime.

      Still, I don't currently run a node because Freenet's slow as fuck and has almost no content (legal or illegal). But I think the concept behind it is incredibly important, and I'll probably start running a node once it gets faster and/or I get a static IP.

    Tor supports something called a "hidden service" which allows you to serve something, such as a web site, ftp, or dare I say, a bittorent link.

    The neat thing is, you can serve the service without anyone knowing your IP address. So you would share a link such as follows: http://6sxoyfb3h2nvok2d.onion/ (which is the tor hidden service wiki BTW). The Tor servers "meet in the middle", thus hiding the originating serving ip address. Read here for more on this functionality.
