Abstract

Building trusted P2P networks is a very difficult task, due to the size of the networks, the high volatility of the nodes, and potential byzantine behaviors. Interest in this area of research is ever increasing, because of the popularity of P2P networks, and their capability to provide a high availability of resources and services. In the last years, reputation systems have shown to be a good solution to build trust in large scale networks. Many papers have been published on this subject, and having a complete understanding on how they work is not easy. In this paper, we make a critical analysis of the most relevant results about reputation systems in the last three years, and propose a classification to clearly discriminate their common advantages and specific problems.
