SAP2P: A security architecture for P2P network applications based on trust management system

Abstract

The P2P network and its applications have the characters of dynamic and self-management, so the classic technologies do not solve the security issues of P2P network such as authentication, authorization and secure communication appropriately. In this paper, we propose a new trust management system called ExSPKI to solve the problem of establishing trust relation. Based on ExSPKI, a security architecture SAP2P (Security Architecture of Peer to Peer Network) is proposed to build the trust relation between the security modules and solves the related security issues. This paper describes definition in ExSPKI and the composition and the protocol of the SAP2P. An implantation is discussed finally.
