  What is OnionRouting ? • Onion routing is a technique for anonymous communication over a computer network. • In an onion network, messages are encapsulated in layers of encryption, analogous to layers of an onion. • The encrypted data is transmitted through a series of network nodes called onion routers, each of which "peels" away a single layer, uncovering the data's next destination. • When the final layer is decrypted, the message arrives at its destination. • The sender remains anonymous because each intermediary knows only the location of the immediately preceding and following nodes. • There are methods to break the anonymity of this technique, e.g. timing analysis.
