SAP2P: A P2P Network Security Architecture based on Trust Management System

摘要

This paper proposes a security architecture that can be used in P2P network named SAP2P. This architecture solved the security problems by realizing a trust management system ExSPKI. In the SAP2P, security policies play the core role of the whole system. Users can realize the management of their own resources by defining and maintaining the security policies. This paper analyzes the characteristics of the P2P network including the scalability, autonomy and cross-platform. And the trust management system ExSPKI fully uses and satisfies the characteristics of the P2P network. By using the ExSPKI system we solve the security problems that cannot be solved or be fully solved by using some traditional security settlements.
