The proliferation of P2P computing has recently been propelled by popular applications, most notably file sharing protocols such as BitTorrent. These protocols provide remarkable efficiency and scalability, as well as adaptivity to dynamic situations. However, none of them is secure against attacks from rational users, i.e., users that misuse the protocol if doing so increases their benefits (e...

Up to now, more and more people use Internet storage services as a new way of sharing. File sharing by a distributed storage system is quite different from a specific sharing application like BitTorrent. And as large file sharing becomes popular, the data transmission rate takes the place of the response delay to be the major factor influencing user experience. This paper introduces strategies ...

Peer to Peer communication has become very popular these days .This popularity and increase in P2P traffic has given birth to many internet traffic management problems for service providers. One of these problems is high download traffic of P2P file sharing application for long network distances ,as current applications do not pay attention to network topology while selecting peers for sharing ...

We present the idea of a web based covert file system, CovertFS. This file system allows a user to store files covertly on media sharing websites while guaranteeing confidentiality and plausible deniability regarding the existence of the files. Further, it allows for selective and covert sharing of these files with other users. CovertFS can be built on top of any web based media sharing service...

While existing research on peer-to-peer (P2P) file-sharing services has increased our understanding in many respects, it has not yet supplied a comprehensive theoretical framework that explains business failures of P2P file-sharing network service models. We develop such an analytical model and base it on seven specific market constraints – technical, economic, structural, legal, political, cog...
