tor? yes and here’s why! The internet is by design open, public, visible, and anything but private or secure. For many of us, most of the time, this isn't an issue let alone a problem. You probably take open access to the internet for granted. You may think it's your right to surf as you see fit. "The government has no right to limit, censor, or restrict where I surf or what I say online." But what if your government spies on its citizens? What if you couldn't visit sites like Google, YouTube, Twitter, or FaceBook? What if surfing got you arrested, imprisoned, or worse? We all cheer when news, photos, and video makes it way out of repressive countries. In many cases the people involved did so at great personal risk. Did you ever ask yourself how they did it? Many people use the Tor network to surf anonymously, protect their privacy, and access parts of the internet that would otherwise be off limits. People in China, Iran, Syria, Burma, and other parts of the world rely on Tor to get around government attempts to censor them and block free access to the net. Tor must be a valuable tool because the Chinese government spends a lot of time trying to cripple it. Tor is a network of computers run by volunteers around the world. Tor shuffles web traffic from computer to computer in an attempt to hide who you are and where you're going. Imagine Alice wants to visit Bob but she's being followed by Eve. Using Tor is akin to Eve jumping from car to bike to bus to subway to taxi to motorcycle making it hard for Eve to keep up with her. When you visit a web site, anyone watching you knows your IP address and the IP address of your destination. In a perfect world, this isn't a problem but if you're in China the results could tragic. Imagine censors looking at a letter and noting Alice's return address as well as the recipient, Bob's address. In this scenario monitoring Alice and Bob is a trivial exercise. Alice puts a letter inside another envelope and mails it to a friend. They open the outer envelope and then mail the envelope inside to Bob. Tor works in much the same way except Alice's "letter" (web traffic) to Bob is inside multiple envelopes (encrypted layers). Everyone (Tor relays) opens the letter they receive, tosses the outer envelope, and remails the next envelope on Alice's behalf. If all the remailers are anonymous strangers (random Tor relays) the most any one person knows is who sent them a letter and who gets it next. As long as there two or more remailers, no one person can recreate the path from Alice to Bob. Alice -> relay-1 -> relay-2 ... relay-n -> Bob This is what Tor does and why it's called The Onion Router. Each envelope or relay is like the layers of an onion. The more relays there are, the harder it is for Eve to recreate the path from Alice to Bob. But there's a tradeoff between increased security (additional relays) and performance (the time it takes to relay each message). There are three kinds of Tor servers: - bridges, where Alice enters the Tor network - relays, computers that pass traffice between themselves - exits, where traffic exits Tor and connects to the internet Tor is a mature open source project so the underlying software and protocols are trustworthy. The weakest links are the computer Alice uses to enter the Tor network (a Tor bridge) and the computer that goes from Tor back out to the internet (a Tor exit). If Eve watches were you enter and where you exit (the Tor bridges & exits), the number of relays in between is irrelevant. Worse case scenario #3: Eve runs a Tor exit so she can identify Bob (but not Alice) Worse case scenario #2: Eve runs a Tor bridge and watches Alice enter the Tor network (in order to hide from Eve) Worse case scenario #1: Eve runs both a Tor bridge and Tor exit and matches traffic coming in and going out and identifies Alice & Bob Moral of the Story: Always use trusted bridges and exits. Better yet, run one yourself and help make the Tor network more secure. Let's tip the ratio of trusted:toxic Tor servers in our favor, making Eve's job harder (not that No Such Agency can't simply bring more virtual machines online to tip the trusted:toxic ratio in their favor). Eve poses two risks: - traffic analysis by observing the Tor traffic through her bridges, relays or exits (a passive adversary) - blocking Alice from using Tor at all (an active adversary) Never underestimate the power of traffic analysis. Eve can run bridges, relays, and/or exits and silently monitor who uses Tor, how often, where they're going, and for how long. Over time she can build a profile of Alice, a classic data mining exercise. Whether you personally use Tor or not, please consider running a Tor server. The more relays there are the more secure Tor is. If you have a spare machine and a broadband connection, it only takes a few minutes to configure a Tor bridge or relay. Then when you see something that's been smuggled out of a censored part of the world, you can take pride in knowing that your contribution helped make the world a safer place to surf. TIA I run Tor servers. Give thought to running a Tor bridge or a Tor relay yourself. Copyright 2012 Jerry Whiting. All rights reserved.

tor the onion router Tor, The Onion Router, omogućava ljudima da surfati anonimno i sigurno ne prati ili cenzurirani. Iako nije savršen, pomoću Tor pomaže mnogim ljudima diljem svijeta izbjeći cenzuru. Mnogi od nas u jako democractic društvima se internet slobodu zdravo za gotovo. U mnogim dijelovima svijeta to nije istina. Događanja u tijeku naglasiti napore vlada da niječu svoje građanima slobodan pristup webu. Tor je jedan alat da oplovi neto cenzure. Postoje mnogi razlozi za korištenje Tor. Kao što je moj otac znao reći, "Bolje da ga ima i ne trebaju, nego da je to potrebno, a ne ga imati." link Grab Tor preglednik paket za svoj OS i surfati malo sigurnije. Ako imate rezervnu stroj ili dvije leži oko i brzu vezu molimo vas da razmislite trčanje Tor okvir. Što se više Tor mostovi i usporivači postoje brže i jače Tor mreža. Vaš doprinos pomaže onima koji traže glasovne online, bez kucanja na vrata. Postoji nekoliko vrsta Tor servera možete izvoditi: Vidalia Bridge bundle : people connect to bridges to enter the Tor network. This helps censored users reach the Tor network. Vidalia Relay bundle : relays pass traffic between random computers as Tor shuffles web traffic to avoid tracking. Vidalia Exit Bundle : exits connect the Tor network back out to the internet. Please read these tips for running an exit node with minimal harassment first. You should definitely read the Electronic Frontier Foundation’s legal FAQ for Tor. Yes, I run a Tor relay or two, and you should run one too. All power to the people! Copyright 2012 Jerry Whiting. All rights reserved.
