IBE-Trust: A security framework for Wireless Sensor Networks

The importance of key management protocol in ensuring secure communications in WSN is undeniable. This paper presents an IBE-Trust security framework utilizing the well-known identity based encryption scheme not to only establish secure communications but to ensure the trustworthiness of the communication between sensor nodes and base station. The framework incorporates ideas from Trusted Computing Group (TCG) and the Identity-based cryptosystem developed by Boneh Franklin in ensuring trusted and secure communications between sender and receiver. The framework and proposed implementation procedures are briefly discussed. The proposed framework which was developed on TinyOS platform was simulated using TOSSIM on Micaz nodes and a study was carried out to compare memory utilizations of the proposed security framework with those obtained in a recent similar work.
