Building secure network using polynomial key pre distribution

Building a secure wireless adhoc network to communicate and sharing data, resource between user based on the key exchange methods. Security services such as authentication and pair wise key establishment are critical to wireless network. So we enable wireless node to communicate more securely with each other using cryptographic techniques. IN this paper we propose polynomial key pre distribution, probabilistic generation key pre distribution scheme. Proposed system is a self-configured secure protocol to create the network and share data without any infrastructure. Finally we analysis and improve the security of the network.
