Abstract: In Wireless Sensor Network security, the open challenge is forming a secure network infrastructure using a bootstrapping protocol. The bootstrapping protocol which is a key pre-distribution technique has to be efficient and not complex as well, since sensor nodes have numerous limitations and constraints such as storage, energy, computational power in it. Also sensor nodes are vulnerable to attacks an authenticated broadcast scheme must be used. Many Key pre distribution schemes have been proposed and each scheme has its own advantages and drawbacks. Based on recent researches it has been proved that public key cryptography can be used in key agreement protocol of wireless sensor networks to establish a secure link among nodes for communication. In our paper, we implement a pre-key distribution scheme using public key cryptography where the public key and private key of each node is distributed as a priori. The public key and private key are generated using RSA algorithm. The Scheme is evaluated with various performance evaluation metrics and graphs are generated using Omnet++ simulator.
