A Novel Dynamic Authentication Method for Sybil Attack Detection and Prevention in Wireless Sensor Networks

Abstract

One of the most concerns in wireless sensor networks is security. Wireless sensor networks are vulnerable to attacks in every layer of the network. They are extremely necessitous for securing network protection. Sybil attack is one of those attacks in which a legal node is converted into a Sybil one which is a replica node with a different personality using a similar ID. This kind of identity theft attack can be classified as Sybil attack. This attack mainly influences routing protocols and operations such as voting, data aggregation and reputation evaluation. This paper proposes a dynamic and accurate method for Sybil attack detection and prevention. The proposed method generates a routing table that holds information about deployed nodes. The base station verifies the keys of nodes that will communicate and transmit data between them. Data transmission occurs between nodes once they get the signal from the base station. The message authentication method will progress data transmission in the network and enhance the throughput compared to RPC.
