As the Internet is becoming a virtual platform for people’s sharing information and communicating daily, more and more people are connected together and the contact area between their personal privacy and the outside world turn to be unprecedented large. Therefore, the users of the Internet are faced with an enormous privacy threat. Anonymous P2P technology is a good way to solve the above problems. The ultimate goal of all anonymous P2P systems is to obtain the anonymity. Anonymity assessment on different anonymous P2P systems can be used to compare the amount of anonymity offered by different systems or to adjust the parameter setting of the same system according to different need, which is of great guiding significance to improve anonymous communication systems. In this paper, from the angle of relationship anonymity between the sender and the receiver, we presents the BIG-MIX anonymity method, taking the paths cross of different messages into consideration, to make anonymity assessment on anonymous P2P networks with the use of mapping. And with this method, this paper makes a quantitative analysis on the relationship anonymity of anonymous P2P networks under the mechanism of Threshold Mixes, Timed Mixes or Pool Mixes.
