An Efficient Novel Key Management Scheme Using NChooseK Algorithm for Wireless Sensor Networks
In Wireless Sensor Networks Key Management is a very challenging phenomenon. This paper gives an illustration and demonstration of mathematical model of new key management scheme which overcomes the limitation of Pre-Shared key scheme, which is extensively used in wireless sensor networks by most of the vendors. The environment of WSN is challenged by many limitations due to which there is an urgent need to manage memory which is consumed while provisioning of the key in the wireless sensor network by using N-choose K algorithm. The authors were successfully able to build a more reliable network in terms of network connectivity .Secondly it offers a scalable solution as there is no need to keep key material of all the network in each sensor node.
