Onion Routing for Anonymous and Private Internet Connections

摘要: Abstract : Preserving privacy means not only hiding the content of messages, but also who is talking to whom (traffic analysis). Much like a physical envelope, simple application cryptography within packet-switched network hides messages being sent, can reveal whom, and how often. Onion Routing general purpose infrastructure for private communication over public [8, 9, 4]. It provides anonymous connections that are strongly resistant both eavesdropping traffic analysis. The bidirectional, near real-time, be used connection-based connectionless traffic. interfaces with off shelf software systems through specialized proxies, making it easy integrate into existing systems. Prototypes have been running since July 1997. As this article's publication, prototype processing more than 1 million Web per month from six thousand IP addresses in twenty countries all main top level domains. [7]
