Analyzing the energy consumption of security protocols

Security is critical to a wide range of wireless data applications and services. While several security mechanisms and protocols have been developed in the context of the wired Internet, many new challenges arise due to the unique characteristics of battery powered embedded systems. In this work, we focus on an important constraint of such devices – battery life – and examine how it is impacted by the use of security protocols. We present a comprehensive analysis of the energy requirements of a wide range of cryptographic algorithms that are used as building blocks in security protocols. Furthermore, we study the energy consumption requirements of the most popular transport-layer security protocol SSL (Secure Sockets Layer). To our knowledge, this is the first comprehensive analysis of the energy requirements of SSL. For our studies, we have developed a measurement-based experimental testbed that consists of an iPAQ PDA connected to a wireless LAN and running Linux, a PC-based da...
