Scalable Secure Routing for Heterogeneous Unstructured P2P Networks

In this paper, we propose a secure routing algorithm based on three simple levels and show its applicability to heterogeneous unstructured overlays. Due to the lack of secure routing protocols for unstructured overlays we have started to investigate a possible solution for these systems. We propose a scalable secure routing protocol for heterogenous environments. Through analytical study and experimental results we demonstrate the secure routing protocols potential in providing a secure topology management service for a broad range of node classes and communication capabilities. We show that it is possible to combine security, scalability and adaptability in one mechanism allowing each node to achieve an adequate level of security to meet the overall system requirements.
