Onion Routing and TOR (Part 2): High-Level Mechanics

In this second video, Sourcefire Chief Scientist, Zulfikar Ramzan, provides a high-level description of the underlying mechanics of Onion Routing, focusing specifically on way that TOR ("The Onion Router") works. TOR uses techniques from cryptography, such as symmetric-key encryption, Diffie-Hellman Key exchange, and public-key encryption to provide improved communications privacy.
