Secure routing strategies in DHT-based systems

Abstract

Due to the inherent characteristics of peer-to-peer systems, one of the barriers to deploy applications over public networks is the different security levels that have to be provided. Peer-to-peer systems are vulnerable to several attacks. In particular, for routing attacks, an adversary attempts to mis-route or drop messages along the routing procedure or corrupt routing table entries, thus degrading the overall routing process. In this paper, we propose a taxonomy of solutions to the routing attack, identify new issues and shape future directions. © 2010 Springer-Verlag.
