Combating Sybil Attacks using SybilGuard
Journal Title: International Journal of Advanced Research in Computer Engineering & Technology(IJARCET) - Year 2013, Vol 2, Issue 2
Abstract
This paper presents a Sybil Guard, for combating against Sybil attacks without relying on a trusted central authority. Peer-to-peer and other decentralized, distributed systems are known to be particularly open to Sybil attacks. In aSybil attack, a malicious user obtains multiple fake identities and pretends to be multiple, distinct nodes in the system. Among the small number of decentralized approaches, our recent SybilGuard leverages a key insight on social networks to bind the number of Sybil nodes accepted. Despite its promising direction, SybilGuard can allow a large number of Sybil nodes to be accepted. Furthermore, Sybil Guard assumes that socialnetworks are fast-mixing, which has never been confirmed in the real world. SybilGuard exploits this property to bind the number of identities a malicious user can create. Sybil Guard offers dramatically improved and near optimal guarantees.
