Analysis of energy consumption on IBE-Trust security framework

Trusted communication recently has become an essential necessity in Wireless Sensor Networks(WSNs) as applications rely more and more on communications with remote platforms. Indeed, the trusted relationship thus far can only be achieved through Trust Management System (TMS) or by adding an external security chip on the platform. While the term trusted has been widely used referring to valid nodes in the group, this paper discusses the term trusted based on the definition provided by the Trusted Computing Group (TCG) and then presents an IBE-Trust security framework utilizing a well-known identity based encryption scheme. The proposed protocol incorporates ideas from Trusted Computing Group (TCG) and Identity-based cryptosystem developed by Boneh Franklin in ensuring that trusted and secured communications can be established between sender and receiver. Analysis on the energy utilization of the proposed trusted authentication protocol running on the ARM11 processor is also presented at the end of the paper. We surmise that the energy utilization needed to establish trust on such a platform is a worthwhile trade-off.
