A plethora of algorithms have been proposed and standardized, providing a wide range of performance trade-off options for developers to choose from. This paper presents a comparative analysis of 22 key software-based lightweight hash functions, including the finalist from the SHA-3 competition. We use a novel benchmark methodology that combines an AVR ATXMega128 microcontroller with the ChipWhisperer cryptanalysis platform and evaluate and compare the various hash functions along several dimensions, including execution speed, % measured in Cycles per Byte (CpB), memory footprint, and energy consumption. Using the composite E-RANK metric, we provide new insight into the various trade-offs each hash function offers to system developers.","short_abstract":"Lightweight hash functions have become important building blocks for security in embedded and IoT systems.
