An Experimental Study on Energy Consumption of Cryptographic Algorithms for Mobile Hand-Held Devices

Abstract

Due to the continuous advancement in technology, mobile devices are playing important role in everyone’s day to day life. Everyone is moving towards wireless mobile systems, but power consumption is an important concern in such devices. While designing, a lot of care has to be taken especially in power optimization because there is no regular power supply in this kind of devices. This paper represents software level cryptographic protocols for optimizing the power consumption in wireless mobile devices. The capacity of battery grows up very slowly, which is insufficient for the electricity that the handheld devices demand, and thus designs and implementations of battery-efficient systems are in urgent need. This work focuses on one important constraint of such devices-battery life-and examines how it is impacted by the use of various security mechanisms.The energy consumption of these algorithms is measured by loading their software level cryptographic protocol implementations through the device’s serial port, running them and measuring their power consumption. Our results will show that proposed cryptographic protocol provides a better security guarantee and acquires much less energy consumption than the existing cryptographic protocols. Finally, performance analysis will show that compared with existing cryptographic protocols, our proposed scheme is to be more simple, secure and efficient.
