![]() In order to hide this knowledge from one’s ISP, one should make use of a high-quality VPN service to act as an entry point to either one’s anonymous network of choice or to the internet at large. When implementing either of these two tools, one must always be aware that one’s ISP can see that he or she is using Tor or I2P (though they cannot determine the content of the traffic itself). Tor provides one with better anonymous access to the open internet and I2P provides one with a more robust and reliable “network within the network,” a true darknet, if you will. In contrast, I2P is generally used by applications that are written specifically to run on the I2P network. Tor functions by providing a proxy on your local machine that you must configure your applications to use (of download specially configured application bundles). This provides the additional benefit of only disclosing half the traffic in the case of an in-network eavesdropper.įrom an application-level perspective there is a fundamental difference between the I2P and Tor networks as well. I2P establishes two independent simplex tunnels for traffic to traverse the network to and from each host as opposed to Tor’s formation of a single duplex circuit. Instead, network routes are formed and constantly updated dynamically, with each router constantly evaluating other routers and sharing what it finds ![]() ![]() ![]() I2P does not rely on a trusted directory service to get route information. I2P performs packet based routing as opposed to Tor’s circuit based routing I2P on the other hand, was designed from day one to be a true “darknet.” The primary use case for Tor is enabling anonymous access of the public internet with hidden services as an ancillary benefit. However, I2P was designed from the ground up to provide a different set of benefits. I2P appears to provide many of the same benefits that Tor does. These are servers that are accessible only from within the Tor network itselfĪmong the various hidden services are various blogs, email servers, and forums. Tor also allows you to run and access what are called “hidden services. Assuming that the content of your traffic does not reveal your identity, this permits you to browse the internet completely anonymously. All the relays in between only know to forward the encrypted payload to the next relay on the circuit. What this means is that your identity and the content of your traffic are cryptographically bifurcated – your entry node knows who you are but not what you are doing and your exit node knows what you are doing but not who you are. It is also important to note that your exit node only knows which intermediate node to send receiving data back to (this is also true for each internal to internal leg of the circuit). Your traffic becomes a small stream in the giant swath of data coming from and entering back into any given exit node. This is one of the ways that Tor helps maintain your privacy online – each exit node is aggregating traffic from many other Tor users and putting it out onto the internet all at once. Finally, your encrypted traffic is decrypted at the exit relay where it is then forwarded out onto the “regular” internet. You can visualize this as layers of encryption being wrapped around your data: this is where the phrase “onion routing” comes from when describing the type of network Tor establishes. Further each hop in transit between the various relays is encrypted using those relays’ cryptographic keys. I2P is used by many people who care about their privacy: activists, oppressed people, journalists and whistleblowers, as well as the average person.Ī system in which the police look for criminals, using very thorough methodsĭuring the circuit creation process, your client exchanges cryptographic keys with the first relay it connects to and begins encrypting traffic back and forth. It is intended to protect communication from dragnet surveillance and monitoring by third parties such as ISPs. I2P is an anonymous overlay network - a network within a network.
