“…Power and energy of the different software versions are also analyzed, and trade-offs from using new instructions and hardware versus conventional software are presented. This paper extends our previous research [4] by enhancing the methodology and analysis of performance, power, and energy profiling and examining implementation trade-offs in greater detail. This paper presents profiling with and without software optimizations and discusses how these optimizations affect power and energy consumption.…”

Software-defined radio (SDR) is a new technology transitioning from research into commercial markets. SDR moves hardware-dominant baseband processing of multiple wireless communication protocols into software on a single chip. New cellular standards, such as HSPA?, LTE, and LTE?, require speeds in excess of 40 Mbps. SNOW 3G is a new stream cipher approved for use in these cellular protocols. Running SNOW 3G in software on our SDR platform provides a throughput of 19.1 Mbps per thread for confidentiality and 18.3 Mbps per thread for integrity. To have secure cellular communications in SDR platforms for these new protocols, the performance of security algorithms must be improved. This paper presents instruction set architecture (ISA) extensions and hardware designs for cellular confidentiality and integrity algorithms using SNOW 3G. Our ISA extensions and hardware designs are evaluated for the Sandbridge Sandblaster TM 3011 (SB3011) SDR platform. With our new SNOW 3G instructions, the performance of confidentiality and integrity improve by 70 and 2%, respectively. For confidentiality, power consumption increased by 2%, while energy decreased by 40%. For integrity, power consumption remained consistent, while energy decreased by 2%.
