Abstract
In this paper, we proposed a Crowds-like architecture to achieve the goal of sender anonymity over existing structured peer-to-peer networks. Users are able to anonymously request both internal peer-to-peer services and external Internet ones via a relay path. One appealing feature of the architecture is the ease of integration, that is, the anonymous path is constructed without modifications to the underlying peer-to-peer networks. Moreover, an optional feature called dummy path composition is provided to resist local traffic analysis attack, and there are also two kinds of routing methods with different degree of anonymity to fulfill user requirements. Through analysis and simulations, we show that our system outperforms existing systems on both performance and anonymity. © 2013 ICIC International.
