Analysis of peer-to-peer distributed reputation schemes

Abstract

Peer-to-peer systems consist of groups of nodes acting as clients and servers. These groups of nodes communicate directly among themselves through wide-area networks. Some of the benefits of fully distributed peer-to-peer systems are scalability, resource aggregation and interoperability without any administration cost or centralized infrastructure support. In this context, reputation schemes aid the service requesters to choose the proper resource provider and to prevent malicious behaviors. This paper analyzes reputation management in fully distributed peer-to-peer systems. This paper discusses the main issues that a reputation framework must address and analyzes the most representative distributed reputation systems. This paper also discusses the main advantages and drawbacks of each proposal in relation to peer-to-peer reputation system requirements
