Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

In this paper, we present a Gigabit Ethernet AES (Advanced Encription Standard) Encription Engine. One of the main push factors in software-defined radio(SDR) is the use of programinable devices such as field programmable gate arrays (FPGAs) or digital a signal processors (DSPs). Including such devices in SDR base station systems allows for reconfiguration and upgrade of the communication system and the application processing. Due to the increased concerns regarding secure information, we have implemented an AES encryption engine for data processing in a SDR system using one of the latest FPGAs available. The engine is capable of simultaneously processing 2 input and 2 output data streams of 1 Gigabit each. As the system has been developed on an inchistrial scalable architecture, a further 3 FPGA daughter cards can be added to the board for further application processing, and each board could be one of many.
