SybilBelief: A Semi-Supervised Learning Approach for Structure-Based Sybil Detection

Abstract: Abstract-Sybil attacks are a fundamental threat to the security of distributed systems. Recently, there has been a growing interest in leveraging social networks to mitigate Sybil attacks.

“…In addition to that, some other works have adopted a hybrid approach combining both topological (i.e., graph‐based) properties and feature‐based classification. Examples are the works of M. Jiang et al () and Laleh, Carminati, and Ferrari (), or the work of Gong, Frank, and Mittal (), where a semi‐supervised classification methodology starting from sets of known honest and sybil nodes was exploited. Another example is the work of Li, Martinez, Chen, Li, and Hopcroft (), where the authors deploy a semi‐supervised process that starts from knowledge on spammer seeds, and tracks the activities and interactions of users with shared videos in Youtube over time by analyzing temporal graphs.…”

“…[12] proposes a fuzzy C-means method to softly cluster the probability of a user being malicious or benign by examining the deterministic sensing reports in a period. In [13], Sybil detection is determined by exploring the existence of users and their connection information. A semi-supervised learning approach is considered with a joint distribution probability over all pre-defined labels of benign or malicious users.…”

“…Then, SybilBelief propagates the label information from the known benign and/or Sybil nodes to the remaining nodes in the system. 23 Compared with above methods, GroupFound is a lightweight algorithm. It does not need training data in advance.…”
