I2P is an anonymous network layer that provides stronger privacy protections than Tor. It uses garlic routing, message bundling and end-to-end encryption over short-lived tunnels to obscure a user's location and activities. Sites hosted on I2P, called eepsites, can only be accessed by other users on the network. While smaller than Tor currently, I2P offers increased security through its fully distributed architecture with no centralized points of control or surveillance.

18. STORY OF ELDO K.
• HARVARD STUDENT
• DIDN’T WANT TO TAKE FINAL EXAM
• EMAILED BOMB THREAT
• USED TOR TO DISGUISE HIMSELF
WHAT HAPPENED?
• ELDO USED UNIV NETWORK TO ACCESS TOR
• HE WAS IDENTIFIED AND ARRESTED IN HOURS
• ELDO SENTENCED TO COMMUNITY SERVICE

19. A BETTER WAY: I2P
INVISIBLE INTERNET PROJECT

20. WHAT IS I2P?
• ORIGINATED IN 2003 AS
INVISIBLENET
• DECENTRALIZED NETWORK
LAYER
• END-TO-END ENCRYPTION
• NO OUTPROXY TO CLEARNET

21. FULLY DISTRIBUTED
SELF ORGANIZING
RESILIENT

22. NO CENTRALIZED
DIRECTORY SERVER

23. PACKET SWITCHED VS.

24. SHORT-LIVED, SIMPLEX

25. HOW IT WORKS
• Layered Encryption
• Message Bundling
• Tunnel Routing
• ElGamal/AES

29. I2P & CRYPTOCURRENCY

30. I2P BOTE SECURE-EMAIL

31. COMPARISON

Less Secure More Secure

32. I2P LIMITATIONS
• NO ACCESS TO CLEARNET
• SMALL USER BASE
• STILL VULNERABLE TO ATTACK
(BUT LESS SO THAN TOR)

33. I2P IS THE FUTURE
