چکیده

We present a trust management system tailored to the needs of the BitTorrent protocol. Unlike other trust management systems, our system is partially decentralized and assumes unstructured BitTorrent swarms. In particular, we use the tracker of each BitTorrent swarm, to compute and distribute global trust scores complementing the local trust scores maintained by each peer. Our simulation study indicates that our system significantly minimizes the downloading by a rogue peer in the swarm. We also found out that it resulted in a fairer allocation of chunks among peers with different link bandwidths.

A Trust Based Cross Layer Security Protocol for Mobile Ad hoc Networks

In this paper, we develop a trust based security protocol based on a cross-layer approach which attains confidentiality and authentication of packets in both routing and link layers of MANETs. In the first phase of the protocol, we design a trust based packet forwarding scheme for detecting and isolating the malicious nodes using the routing layer information. It uses trust values to favor pack...

Trust in Peer-to-Peer Content Distribution Protocols

The distribution of virtual goods like multimedia data relies on the trustworthiness of the distribution system. Recent concepts for the distribution based on peer to peer networks like BitTorrent require new approaches to establish the needed level of trust in the overall functionality of the system. This paper explores the integration of hardware based trust concepts from the domain of Truste...

Analysis of BitTorrent and its use for the Design of a P2P based Streaming Protocol for a Hybrid CDN

Peer-to-peer (P2P) based networks have several desirable features for content distribution, such as low costs, scalability, and fault tolerance. However, they fail to provide guarantees for content delivery. In order to combine the desired features of classical Content Distribution Networks (CDNs) and P2P based networks, we propose a hybrid CDN structure with a P2P based streaming protocol in t...
