![]() The first node in the Tor network ( the Guard Server) can see that a message is coming from your specific IP address, and where it is supposed to send the message next. No node (server) in the Tor network can see all the information it would need to identify you and tie you to a specific date. They can only see that you are connected to Tor. Tor is designed so that your ISP and anyone watching your computer’s connection to the Internet cannot read your message. Tor protects each piece of the message in three layers of encryption, a technique called “ onion routing.” One layer of encryption gets stripped off at each server along the path, and the message exits the Tor network in its original (pre-encryption) state. The message is encrypted and passes through three randomly selected servers using encrypted tunnels. It uses a network of volunteer-run servers to pass a message between your computer and a resource on the Internet. Tor is an anonymity system with millions of users worldwide. ![]() Now that you’ve got a good sense of what I2P is all about let’s take a look at how I2P compares with two other privacy-oriented technologies: Tor Vs VPNs. An app called I2PSnark allows you to stream videos and other content across the I2P network using the BitTorrent protocol. I2PTunnel also makes it possible to create an anonymous IRC network.Īnother feature of this design is the ability to support streaming apps. The I2PTunnel service allows users to create and host an anonymous eepsite using a standard web server. Users on the I2P Network?Īmong other things, this means that once you connect to I2P, you can use a standard web browser to view eepsites and other resources. This lets you find the Inbound Tunnels of others using I2P. To find other users of I2P, you can consult the fully-distributed I2P network database. This means that the characteristics of the total connection between two users of I2P can vary greatly. The owner of the destination controls the length of those tunnels. Note, however, that a user has control only over the length of his or her own tunnels. Tunnels with more hops provide greater anonymity, but result in reduced reliability and throughput, while increasing latency. This allows users to balance anonymity, latency, throughput, and reliability as best serve their own needs. ![]() The length of each user’s Inbound and Outbound Tunnels is under their control. 2-(or more)-hop tunnel – A tunnel where there are one or more routers between the Gateway and the Endpoint.1-hop tunnel – A tunnel where the Gateway connects directly to the Endpoint.0-hop tunnel – A tunnel where the Gateway is also the Endpoint.Without getting into the technicalities of threat modeling, I2P provides at least some protection against the following threats: Any system that provides any level of anonymity will protect us from most of the threats we are likely to see used against us. Does I2P provide perfect anonymity?īut for most of us, the threats are less urgent, and the value of capturing our information isn’t worth the expenditure of huge resources. For high-risk targets like whistleblowers, activists, and human rights activists, incorrectly modeling threats to their anonymity could cost their lives or freedom. Your threat model tells you who is likely to attack you, how they are likely to attack, and what they are likely to want to learn. Which takes us to the concept of a threat model. Whether that can or will happen depends on who that hostile someone is and what resources they are willing to use against you. Getting your information requires someone hostile to you to defeat one of these factors and the willingness to expend the resources to do so. The internal architecture of the system.With coders all around the world reviewing the code and looking for bugs or intentionally-inserted weaknesses, I2P is surely safer to use than most commercial software. Who would you lean on to do something underhanded like put a backdoor into the code?Īdd the fact that the I2P code is FOSS (Free and Open Source Software). On the other hand, this makes it a lot harder to put pressure on the team. And, as far as we can tell, there are no big financial backers. ![]() On the one hand, there isn’t some corporation or university to drive the project forward and be held responsible if something goes wrong. The distributed, mostly volunteer, and partially anonymous nature of the team has advantages and disadvantages. You can see the most up-to-date list on the I2P Project Members page. Here is a partial list of the project team as of December 2018: I2P Project Member List As befits an anonymous messaging system, the people who develop and manage I2P are mostly anonymous themselves.
