Key Management Protocol for Wireless Ad-Hoc Sensor Networks

Abstract

In this fast moving world, connectivity plays a significant part. Ad hoc networks play a prominent role in the context of communication today. The need for connectivity can be varied from a simple transfer of an image, to a complex message passing for military purposes and it has been changed to transfer data in secure manner from transferring the data with less security. Wireless links are vulnerable to undemanding eavesdrop. When security aspects of wireless ad hoc networks are considered, it is totally depended on key generation and key management protocol. Lack of centralized authority, certificate authority and dynamic topology represent foremost difficulties in providing security in key management. This research has introduced a design and implementation of new key management protocol in order to overcome drawbacks of existing protocol that work within ad hoc nature. This is based on the concept everyone should participate , meaning all nodes participated to encryption process should also participate decryption process too, holding their portion of key. Elliptic Curve Cryptography and its strong mathematical concepts are used to achieve main goals of the protocol.
