Detecting Sybil Nodes in Anonymous Communication Systems
2013
Procedia Computer Science
As one of the most fundamental problems in open-membership systems, Sybil attack has attracted wide attentions from both industrial and academic fields. Many anonymous communication and censorship-resistant systems have incorporated Sybil defense in their designs based on social networks. This paper proposed two-class undirected mixed membership stochastic blockmodels Different from existing algorithms, our model discriminates Sybil nodes by simulating the generative process of social networks.
