| Outline of Final Research Achievements |
In this study, we propose several methods to minimize the overall cost to bound malicious behavior of peers participating in a P2P system. More concretely, we propose a method to calculate the reliability of peers in unstructured P2P and verified that the method reduces the complexity of previous methods such as EigenTrust. We further propose a calculation method for structured P2Ps which uses the overlay based on the contracted star graph.
