Fighting Cheating in P2P-based MMVEs with Disjoint Path Routing
Abstract
In a P2P-based Massively Multiuser Virtual Environment (MMVE) where
nodes cannot be trusted, replicating data on multiple nodes is a possibility to increase
the reliability to obtain correct data. Current structured P2P networks mostly
place replicas in such a way that queries for the replicas travel along similar paths.
A malicious node in the common part of all paths can nullify the security gain of
replicated data. We therefore propose to combine radix-based prefix routing with a
symmetric replication scheme to gain disjoint paths to each of the replicas.
