Exploiting Internet Delay Space Properties for Sybil Attack Mitigation

Recent studies have discovered that the Internet delay spac e has many interesting properties such as triangle inequality vi olations (TIV), clustering structures, and constrained growth. Und erstanding these properties has so far benefited the design of networ k m dels and network-performance-aware systems. In this paper, we consider an interesting, previously unexplored connection be twe n Internet delay space properties and network locations. We sho w that this connection can be exploited to mitigate the Sybil attac k problem in peer-to-peer systems.
