Wireless sensor networks constitute of sensor nodes which are running on battery, small in size, limited memory, computation power and communication capability. Operational environment of sensor nodes is generally unfavorable and unattended which may result in failure of sensor nodes and they are prone to various malicious attacks. One of these attacks is Sybil attack. In this paper Sybil attack is prevented using cryptography. This paper shows the effect of Sybil attack in wireless sensor network and also shows the effect of proposed algorithm on network performance in presence of Sybil nodes.
