Public Key Techniques for Prevention of Resource Exhaustion Attack in Wireless Sensor Networks

This paper proposes a prevention mechanism for resource exhaustion attack in Wireless Sensor Networks (WSN). WSNs are widely used in science, medical, and military applications. However, WSN has problems of small memory, weak processors, and the limited battery power. On the other hands, public key techniques provide powerful security, but they need high energy, memory, computation cost than the symmetric cryptography. Therefore, we propose a more efficient protocol than the existing protocols in WSN, which analyze RSA algorithm and simulate ECC algorithm in CC2420 which is a true single-chip 2.4Ghz IEEE 802.15.4 compliant RF transceiver designed for low-power and low voltage wireless application. We also compared our proposed protocol and other public key-based protocols.
