Analysis of energy consumed by secure session negotiation protocols in wireless networks

Abstract

Traditionally, researchers have focused on security, complexity, and throughput metrics while designing security protocols for wired networks. Deployment of these security protocols in battery-powered mobile devices has elevated energy consumption into an important design metric. In this paper we study the energy consumption characteristics of secure session negotiation protocols used by IPSec and WTLS protocols. Based on this study we present techniques to optimize energy consumed by secure wireless session negotiation protocols. Proposed techniques achieve 4x to 32x energy savings without compromising the security of wireless sessions. We show that these techniques are platform independent and discuss the impact of platform specific characteristics, such as available system resources, on the presented techniques. © Springer-Verlag Berlin Heidelberg 2003.
