TY - JOUR AU - Syverson, Paul AB - David Goldschlag, Michael Reed, and Paul Syverson One way to camouflage communication over a public network is to mingle connections from a variety of users and applications to make them difficult to distinguish. Onion Routing for Anonymous and Private Internet Connections P reserving privacy means not only hiding the content of messages, but also hiding who is talking to whom (traffic analysis). Much like a physical envelope, the simple application of cryptography within a packet-switched network hides the contents of messages being sent, but can reveal who is talking to whom, and how often. Onion Routing is a general-purpose infrastructure for private communication over a public network [3, 4, 6]. It provides anonymous connections that are strongly resistant to both eavesdropping and traffic analysis. The connections are bidirec- tional, near real-time, and can be used for both connection-based and connectionless traffic. Onion Routing interfaces with off-theshelf application software and systems through specialized proxies, making it easy to integrate into existing systems. Prototypes have been running since July 1997. At press time, the prototype network is processing more than one million Web connections per month from more than six thousand IP addresses in twenty countries and in all six TI - Onion routing JF - Communications of the ACM DO - 10.1145/293411.293443 DA - 1999-02-01 UR - https://www.deepdyve.com/lp/association-for-computing-machinery/onion-routing-dXYImjAVW5 SP - 39 VL - 42 IS - 2 DP - DeepDyve ER -
