A general approach to achieve anonymity on P2P networks is to construct an indirect path between client and server for each data transfer. The indirection, together with randomnes...
Several caching techniques have been used to reduce the bandwidth consumption and to provide faster answers in P2P systems. In this paper, we address the problem of reducing unnec...
