Abstract

The P2P network and its applications have the characters of dynamic and self-management, so the existing technologies do not solve the security issues of P2P network appropriately. In this paper, we describe new techniques that overcome many of the cited difficulties. We propose a new security architecture named SAP2P to address the security problems in P2P network. The core of SAP2P is based on a trust management named ExSPKI that establishes the trust relationships between peers. This architecture is adapted to the features of P2P network.
