Abstract
This theis is aimed at proposing asingle-node architecture that integrates both active routing and p2p net working. In the proposed architecture, each node consists of five layers; link layer(eathenet) node operating systems layer ,p2p net working layer in the proposed architecture each node consist of five layers link layer ehernet node operating system layer p2b networking layer extension layer and active packet layer to enhance the security of the proposed architecture tow security layers are added one to compute the node reputation and the second to provide an authentication scheme.such scheme may be eathier centeral or hierachical the proposed and the secure active routing architectures for p2p networks are rested and their performanbces are evaluated .
