Presentation on Invisible Internet Project (I2p)

1. I2P – Invisible Internet Project
By Shail K Shah

2. What is I2P?
• I2P, short for the Invisible Internet Project,
created in 2003,it is an anonymizing network
that focuses on secure internal connections
between users.
• I2P focuses on creating its own internal
internet so that the network isn't accessible
from a regular computer, as special software is
needed to communicate with other I2P users.

4. How I2P works?
• Think of the mail system. Imagine that you had two
mailboxes: one that you receive mail in, and one that you
send mail through. Imagine also that your friend Charlie
had the same thing, as well as everyone else in your
neighbourhood.
• The way I2P works is that if you want to send a message to
Charlie you place the letter in your outgoing mailbox
addressed to him.
• Then three neighbours pass the letter off to each-other,
with each neighbour not knowing who the letter came
from before the person that handed it to them. These
people are analogous to what we call a 'tunnel' in I2P.

5. • After the letter reaches the end of this tunnel, it goes
to Charlie’s tunnel. So it goes to one person, who
hands it to another, who hands it to another, etc.,
until it reaches Charlie.
• If Charlie want's to send a letter back this process
happens in reverse (but with a different set of people
handling the messages).
• Furthermore, with I2P there are thousands of letters
being all passed around at the same time, and I2P
puts multiple messages into one encrypted packet,
making it harder for an outside observer to find out
what's going on. This is basically how I2P works.

of
I2P

8. Eepsites
• Eepsites are the I2P equivalent of a Tor Hidden
Service: they are websites hosted on the I2P
network, whose operators can be anonymous.
• Like hidden services, these sites cannot be
connected to off the I2P network.
• Eepsites are an excellent way to host websites
anonymously, and there are a ton of great
eepsites that you could visit. They have an
.i2p extension.

9. Email(Susimail)
• Susimail is a web-based e-mail client for the I2P
network.
• Susimail was created to address privacy concerns in
using these servers directly using traditional email
clients, such as leaking the user's hostname while
communicating with the SMTP server.
• Susimail is a web-based email client intended primarily
for use with Postman's mail servers, and is designed
with security and anonymity in mind.
• It is currently included in the default I2P distribution,
and can be accessed through the I2P router console
web interface.

11. IRC (Internet Relay Chat)
• IRC's are basically chat rooms online, and I2P has
an IRC service that allows users to chat
anonymously.
• The best part is that I2P's anonymity offers a
near-perfect sense of freedom of speech.
• Often controversial topics are talked about in
these channels, but nobody is afraid of offering
what may be a very valid, but unpopular opinion,
pushing you to explore new ideas from new
perspectives.

13. Torrenting
• One of the features that attracts a lot of people to i2p
is torrenting, as I2P has the Postman Tracker and
I2PSnark.
• The tracker is essentially the Pirate Bay, and I2PSnark is
essentially uTorrent. On I2P, torrenting is secure and
anonymous as it has privacy by design rather than
privacy by policy.
• There are plenty of books, including huge collections
on sci-fi and programming. There are also copies of the
Pirate Bay, backups of leaked government documents,
and books that have been banned in some countries.
