Analysis of Software AES in SparrowE Wireless Sensor Networks

Wireless sensor networks are a cheap and versatile solution for monitoring various environments. The data gathered by these sensors is often used in research projects and science experiments. It is necessary to ensure that a certain level of security and protection is instated for the transmitted data. Current software security methods implemented on wireless sensor networks do not necessarily take into consideration the lifetime and autonomy of the nodes. This paper presents an analysis of a software AES implementation on SparrowE wireless sensor nodes and shows a comparison between the viability of such a method with regard to hardware AES.
