Energy Consumption for Cryptographic Algorithms with Different Clocks on Smart Cards in Mobile Devices
In mobile devices, smart cards become the trend and are used in numerous applications and services. Since mobile devices are battery-powered, so it is important to find energy saving solutions to reduce energy consumption. Most mobile devices are powered by batteries with limited power capacity. In order to protect information during the communication process, security system designers use many cryptographic algorithms to protect user data. The encryption technology will consume considerable power. The Cryptographic algorithms are implemented on a security chip that is embedded in a smart card. When the CPU clock changes the execution time and the energy consumption will thus change. In this paper LabView2010 and related hardware are used to build a power measurement environment.
