Zenggang Xiong, Xuemin Zhang, Li Liu, Jianxin Chen · Journal of Networks · 2011
Abstract — Grid and P2P systems enable users to share resources across organization boundaries. Security is a major element in any Grid infrastructure, as it is necessary to ensure that only authorized access is permitted. P2PGrid systems have a different set of security requirements contrary to the traditional server based centralized grid systems. This paper proposes a decentralized security framework for P2PGrid systems. This paper analyzes the unique security requirements of large-scale grid computing and develops a reputation-based security policy and corresponding security architecture. Theoretical analysis and simulations prove that the reputation-based security framework can adapt the security in P2PGrid.
