Abstract: Trust is an important tool in human life to cope with the uncertainty caused by the free will of others. Uncertainty and uncontrollability are also important issues in peer-to-peer (P2P) environments. A computational model of trust and its implementation can alleviate this problem. In this paper, we design a pyramidal trust management (PTM) model inspired from some phenomena of social networks. First, we propose the algorithms for trustworthiness evaluation, trust community formation, and PTM. Then, we describe the system implementation to demonstrate how to derive the trust mechanisms enhanced security solutions for peers| protection and QoS of network. Finally, we demonstrate through simulation that there is a significant improvement in network performance by applying the proposed trust management architecture.

Keywords: peer-to-peer networks; P2P networks; social networks; trust management; trust community; pyramidal trust management; PTM; computational modelling; trustworthiness evaluation; simulation; network performance.
