Elliptic Curve based r out of n Key Distribution Scheme for Hierarchy Wireless Sensor Networks

( Volume 5 Issue 3,March 2018 ) OPEN ACCESS

C.Porkodi, K.Sangavai


Wireless Sensor Networks (WSNs) widely used in many sensitive fields like target tracking, battle field surviellance, intruder detection, health care and hostile environments. In such applications, the security of data transmission is an important issue and it is achieved through cryptographic algorithms. Key establishment is a primary security service in sensor networks and it facilitates sensor nodes to communicate securely with each other. In this paper, a ‘r out of n” key distribution scheme based on elliptic curve cryptography is proposed. The computational overhead of the nodes in the network is reduced and the survival time of the network is extended in the proposed scheme as the base station is involved in the majority of the computations.
