Peer-to-peer computing has emerged as a significant paradigm for providing distributed services, in particular collaboration for content sharing and distributed computing. However, this computing paradigm suffers from several drawbacks that obstruct its wide adoption. Lack of trust between peers is one of the most serious issues, which causes security challenges in the P2P systems. This paper studies the feasibility to build up trust collaboration based on Trusted Computing Platform (TCP) in peer-to-peer systems. Based on analysis, the authors conclude that the TCP technology is a promising solution that can overcome many P2P security challenges, thus realize trust collaboration among P2P peers.
