A Survey of Solutions to the Sybil Attack
Many security mechanisms are based on specific assumptions of identity and are vulnerable to attacks when these assumptions are violated. For example, impersonation is the well-known consequence when authenticating credentials are stolen by a third party. Another attack on identity occurs when credentials for one identity are purposely shared by multiple individuals, for example to avoid paying...
متن کاملThe Sybil Attack
Large-scale peer-to-peer systems face security threats from faulty or hostile remote computing elements. To resist these threats, many such systems employ redundancy. However, if a single faulty entity can present multiple identities, it can control a substantial fraction of the system, thereby undermining this redundancy. One approach to preventing these “Sybil attacks” is to have a trusted ag...
متن کاملSybil Attack in Wireless Sensor Networks: A Survey
The wireless sensor networks are prone to various attacks; this is primarily due to the fact that these networks once deployed are left unattended. So any attacker with the intention of stealing the information from the network can compromise any node and gain access to the data being propagated in the network. Various attacks possible are black hole attack, wormhole attack, Sybil attack, clone...
متن کاملQuantifying Resistance to the Sybil Attack
Sybil attacks have been shown to be unpreventable except under the protection of a vigilant central authority. We use an economic analysis to show quantitatively that some applications and protocols are more robust against the attack than others. In our approach, for each distributed application and an attacker objective, there is a critical value that determines the costeffectiveness of the at...
متن کاملVarious OSI Layer Attacks and Countermeasure to Enhance the Performance of WSNs during Wormhole Attack
Wireless sensor networks are networks having non wired infrastructure and dynamic topology. In OSI model each layer is prone to various attacks, which halts the performance of a network .In this paper several attacks on four layers of OSI model are discussed and security mechanism is described to prevent attack in network layer i.e wormhole attack. In Wormhole attack two or more malicious nodes...
