What is Sybil Attack in Wireless Networks
Networking , Technology & Science / March 7, 2018

Wireless networking is inherently insecure. Wireless technologies, in the simplest sense, enable one or more devices to communicate without physical connections without requiring network or peripheral cabling. Security in computer world determines the ability of the system to manage, protect and distribute sensitive information. An ever-existing concern is the lack of security due to the very fact that the technology is wireless and is vulnerable to security threats & attacks. Many security mechanisms are based on specific assumptions of identity and are vulnerable to attacks when these assumptions are violated. Overview of Sybil Attack The Sybil attack in computer security is an attack wherein a reputation system is subverted by forging identities in peer-to-peer networks. A Sybil attack is one in which a malicious node on a network illegitimately claims to be several different nodes simultaneously. If an entity on a network does not have physical knowledge of the other entities, it will perceive them purely as informational abstractions called identities. . By illegitimately infusing false or biased information via the pseudonymous identities, an adversary can mislead a system into making decisions benefiting herself The term Sybil attack is to denote an attack where the attacker (Sybil node) tries to…
