Exploiting Trust and Distrust Information to Combat Sybil Attack in Online Social Networks [chapter]

Huanhuan Zhang, Chang Xu, Jie Zhang
2014 IFIP Advances in Information and Communication Technology  
Due to open and anonymous nature, online social networks are particularly vulnerable to the Sybil attack, in which a malicious user can fabricate many dummy identities to attack the systems.  ...  In this paper, we propose an unified ranking mechanism by leveraging trust and distrust in social networks against such kind of attacks based on a variant of the PageRank-like model.  ...  This work is supported by the MoE AcRF Tier 2 Grant M4020110.020 and the ACI Seed Funding M4080962.C90 awarded to Dr. Jie Zhang.  ...

The design of a reliable reputation system

Gayatri Swamynathan, Kevin C. Almeroth, Ben Y. Zhao
2010 Electronic Commerce Research  
Zero accountability via anonymous online identities and divergent interests result in selfish behavior that can disrupt or manipulate networks for personal gain.  ...  Finally, we present our solutions to address the two leading reasons for erroneous and misleading values produced by reputation systems today, i.e., user collusion and short-lived online identities.  ...  Information from social networks can be exploited to enhance many practical areas of research.  ...

Combating Software and Sybil Attacks to Data Integrity in Crowd-Sourced Embedded Systems

Akshay Dua, Nirupama Bulusu, Wu-Chang Feng, Wen Hu
2014 ACM Transactions on Embedded Computing Systems  
To address these attacks, we develop (i) a Trusted Sensing Peripheral (TSP) enabling collection of high-integrity raw or aggregated data, and participation in applications requiring additional modalities  ...  Data integrity becomes imperative as malicious participants can launch software and Sybil attacks modifying the sensing platform and data.  ...  The TSP has built-in sensors, and a Trusted Platform Module (TPM) that helps it resist software and Sybil attacks to its platform.  ...
