The peer-assisted CDN is a new content distribution paradigm supported by CDNs (e.g., Akamai), which enables clients to cache and distribute web content on behalf of a website. Peer-assisted CDNs bring significant bandwidth savings to website operators and reduce network latency for users. In this work, we show that the current designs of peer-assi...

... delivery via peers can start to operate when the system is sufficient to pre- serve the required anonymity as discussed in Section 3.4. We illustrate how peer v A fetches a resource R from v C via a 3- node circuit (as shown in Figure 11) step by step. -1 : Peer v A issues a request for a resource R to the peer server v P ; -2 : After receiving the request, v P first searches for online peers having R. Then v P sets up a 3-node circuit based on the configuration, constructs the packet below with layered encryption, and responds v A with the packet. ...

... The exit nodes abuse remains an intractable problem in Tor, especially after the event of Dan Egerstad [33], who built a Tor exit node and obtained critical information of 1000 foreign government email accounts by analyzing the traffic through it. On the other hand, for P2P anonymous communication network, like I2P [7], although it is possible to build a peer-to-peer (P2P) web caching, participants may not be able to share more resource than their bandwidth [23]. Squirrel [34] is a promising approach for P2P web caching, but it identifies a resource by the hash of the request, so it cannot guarantee the integrity of the content from peers. ...
