Even though anonymizing Peer-To-Peer (P2P) systems often incurs extra traffic costs, many systems try to mask the identities of their users for privacy considerations. Existing anonymity approaches are mainly path-based: peers have to pre-construct an anonymous path before transmission. Proposing Rumor Riding (RR), a lightweight mutual anonymity protocol for decentralized P2P systems. RR employs a random walk scheme - frees the peers from the heavy load of path construction. Previous RSA-based anonymity approaches, RR also takes advantage of lower cryptographic overhead by mainly utilizing a symmetric cryptographic algorithm to achieve anonymity.
