Article: Trust algorithms in P2P file sharing networks Journal: International Journal of Internet Technology and Secured Transactions (IJITST) 2010 Vol.2 No.1/2 pp.174 - 200 Abstract: Many peer to peer (P2P) networks are used to share different types of files between users who are usually anonymous. To prevent the distribution of files that have been intentionally damaged, filled with false content or infected with malware, users need to be able to distinguish between trustworthy and malicious peers. One way to help a user in separating the good peers from the bad peers, is to provide him/her with a sophisticated trust algorithm that calculates the trustworthiness of any peer involved in a file sharing transaction. In this paper the results of a comparative study are presented as a first contribution. This study is based on taxonomy of 17 trust algorithms as found in literature. The evaluation is done by means of both a literature study and a series of simulation tests. By using the evaluation results, the advantages of each of the current algorithms are singled out, and next combined to develop and implement a new and better trust algorithm for file sharing in P2P networks. This is the second contribution. Inderscience Publishers - linking academia, business and industry through research

Abstract: Many peer to peer (P2P) networks are used to share different types of files between users who are usually anonymous. To prevent the distribution of files that have been intentionally damaged, filled with false content or infected with malware, users need to be able to distinguish between trustworthy and malicious peers. One way to help a user in separating the good peers from the bad peers, is to provide him/her with a sophisticated trust algorithm that calculates the trustworthiness of any peer involved in a file sharing transaction. In this paper the results of a comparative study are presented as a first contribution. This study is based on taxonomy of 17 trust algorithms as found in literature. The evaluation is done by means of both a literature study and a series of simulation tests. By using the evaluation results, the advantages of each of the current algorithms are singled out, and next combined to develop and implement a new and better trust algorithm for file sharing in P2P networks. This is the second contribution.
