Exploiting Internet Delay Space Properties for Sybil Attack Mitigation

Recent studies have discovered that the Internet delay space has many interesting properties such as triangle inequality violations (TIV), clustering structures, and constrained growth. Understanding these properties has so far benefited the design of network models and network-performance-aware systems. In this paper, we consider an interesting, previously unexplored connection between Internet delay space properties and network locations. We show that this connection can be exploited to mitigate the Sybil attack problem in peer-to-peer systems.
