摘要：The traditional encryption methods pay more attention to the confidentiality of the message content, but ignore the protection of identity information to the communicating parties. By encrypting, the contents of the communication acquired by attackers became relatively difficult, but they can still found the identity information of the two sides to communicate easily because in the TCP / IP protocol, the sender and receiver of the message are exposed. The anonymity communication technology, is used to solve this problem. The first anonymity communication technology can date back to 1981, Chaum proposed MIX [1] which is a very important technology for reference by a number of researchers of anonymity communication. The rapid development of the Internet has made things convenience to people, but also led to more personal information exposed to the public. As a result, a growing number of areas that required anonymity communication technology to protect the user's privacy. P2P file-sharing is not exception. P2P is undoubtedly the most popular way for file-sharing, but popular P2P file-sharing protocols, such as BitTorrent, can’t provide users anonymity communication service. Many people choose to build upon existing anonymous communication tools, such as Tor, to achieve anonymous P2P file transfer, but Tor primarily provides anonymous service for web browsing, instant message or other low latency applications. A large number of P2P file traffic will seriously threaten the service of Tor. Therefore, the anonymity communication service specifically for P2P file sharing system is very important. In this paper, we presents an anonymity communication scheme specifically for P2P file-sharing networks called F-Crowds which based on Crowds [2] to provide an adjustable anonymity service for P2P file-sharing.
