Tor: anonyymisesti verkossa
Tor is a software project that helps you defend against traffic analysis, a form of network surveillance that threatens personal freedom and privacy, confidential business activities and relationships, and state security. Tor protects you by bouncing your communications around a distributed network of relays run by volunteers all around the world: it prevents somebody watching your Internet connection from learning what sites you visit, and it prevents the sites you visit from learning your physical location. Tor toimii erilaisten ohjelmien kanssa, kuten esimerkiksi Internet-selainten, pikaviestintä-ohjelmien tai monien muiden TCP-protokollaa käyttävien ohjelmien kanssa.
Hundreds of thousands of people around the world use Tor for a wide variety of reasons: journalists and bloggers, human rights workers, law enforcement officers, soldiers, corporations, citizens of repressive regimes, and just ordinary citizens. Vilkaise Who Uses Tor? -sivua huomatakseen esimerkkejä tyypillisistä Tor-käyttäjistä. Selaa yleiset-sivua nähdäkseen lisää tietoa mitä Tor tekee, minkä takia monenlaiset käyttäjät ovat tärkeitä ja kuinka Tor toimii.
There are three pieces of fine print you need to know about.
- Tor does not protect you if you do not use it correctly. Read our list of warnings and make sure to follow the instructions for your platform carefully.
- Even if you configure and use Tor correctly, there are still potential attacks that could compromise Tor's ability to protect you.
- No anonymity system is perfect these days, and Tor is no exception: you should not rely solely on the current Tor network if you really need strong anonymity.
Tor's security improves as its user base grows and as more people volunteer to run relays. (It isn't nearly as hard to set up as you might think, and can significantly enhance your own security against some attacks.) If running a relay isn't for you, we need help with many other aspects of the project, and we need funds to continue making the Tor network faster and easier to use while maintaining good security. Ole hyvä ja lahjoita.
Uutiset
- 25 Toukokuuta 2008: Tor vastaanottaa kaksi palkintoa NLnet-säätiöltä. Ensimmäinen on parantaakseen piilopalveluita. Toinen on parantaakseen Tor-ohjelman toimintaa käyttäjille joilla on vain vähän kaistaa.. NLnet:in palkinnot-sivulla on lisätietoa näistä kahdesta projektista.
- 13 Toukokuuta 2008: Tor 0.2.0.26-rc replaces several V3 directory authority keys affected by a recent Debian OpenSSL-ohjelmointivirhe. Tämä on kriittinen turvallisuusjulkaisu. Jokainen joka käyttää mitä tahansa versiota 0.2.0.x -sarjasta kannattaa päivittää, vaikka käyttää tai ei käytä Debiania. Also, all servers running any version of Tor whose keys were generated by Debian, Ubuntu, or any derived distribution may have to replace their identity keys. See our security advisory or the blog follow-up for full details. As always, you can find Tor 0.2.0.26-rc on the downloads page.
- Etsimme aktiivisesti uusia sponsoreita ja rahoituksia. If your organization has an interest in keeping the Tor network usable and fast, please contact us. Sponsors of Tor also get personal attention, better support, publicity (if they want it), and get to influence the direction of our research and development. Please donate.
