Random Key Pre-Distribution Techniques against Sybil Attacks
Sybil attacks pose a serious threat for Wireless Sensor Networks (WSN) security. They can create problems in routing, voting schemes, decision making, distributed storage and sensor re-programming. In a Sybil attack, the attacker masquerades as multiple sensor identities that are actually controlled by one or a few existing attacker nodes. Sybil identities are fabricated out of stolen keys, obt...
متن کاملSmoke Screener or Straight Shooter: Detecting Elite Sybil Attacks in User-Review Social Networks
Popular User-Review Social Networks (URSNs)— such as Dianping, Yelp, and Amazon—are often the targets of reputation attacks in which fake reviews are posted in order to boost or diminish the ratings of listed products and services. These attacks often emanate from a collection of accounts, called Sybils, which are collectively managed by a group of real users. A new advanced scheme, which we te...
متن کاملSybil Belief: A Semi- Creation New Approach for Structure –Based Sybil Detection
Sybil attacks are a fundamental threat to the security of distributed system. There has been a growing interest in leveraging social network to mitigate Sybil attacks. We introduce Sybil belief a semi supervised learning framework to detect Sybil nodes. Sybil Belief takes a social network of the nodes in the system, a small set of known benign nodes, and, optionally, a small set of known Sybil’...
متن کاملSurvey of Sybil Attacks in Social Networks
This paper reviews the Sybil attack in social networks, which has the ability to compromise the whole distributed network. In the Sybil attack, the malicious user claims multiple identities to compromise the whole network. Sybil attacks can be used to change the overall ranking in voting applications, bad-mouth an opinion, access resources or to break the trust mechanism behind a P2P network. I...
متن کاملA Time-series Clustering Approach for Sybil Attack Detection in Vehicular Ad hoc Networks
Sybil attack is a security threat wherein an attacker creates and uses multiple counterfeit identities risking trust and functionality of a peer-to-peer system. Sybil attack in vehicular ad hoc networks is an emergent threat to the services and security of the system. In the highly dynamic environment of vehicular ad hoc networks, due to mobility and density of nodes, it is challenging to detec...
