DHT Secure Routing Based on Route Convergence Detection

In order to reduce the harm of malicious nodes to the Distributed Hash Table(DHT) network,this paper makes in-depth analysis about the DHT routing algorithm.The iteration function of routing on DHT is done,through the analysis of iterative routing functions.The common features of malicious nodes are summarized,which are used to undermine the convergence of routing.So a security routing model based on convergence is designed detected about route in DHT,which is named SDRM.A security routing algorithm named CSDSR is designed,by SDRM and Chord.A simulation is carried out to verify performance of CSDSR.
