| Abstract(in English) | This paper studies state-of-the-art software implementation of lightweight hash primitives from embed- ded system programmer's standpoint. In embedded environments, due to many possible variations of ROM and RAM size combinations, it is not always easy to obtain an entire performance picture of a given primitive and to create a fair benchmark from the top speed records. In this study we classify these size combinations into several categories and optimize operation speed in each category. We implemented eight hash functions, SHA-256/512, Keccak256/512, Skein256/512, and Gr0stl-256/512, on Renesas' RL78 microcontroller with various combinations of ROM and RAM sizes to make performance characteristics of the primitives clearer. We also discuss how to create an interface and measure size and speed of a given primitive from a practical point of view. As a result, our SHA codes achieve top class speed in most categories. For another implementation aiming at minimizing the ROM size, we have achieved 453-byte Keccak and 396-byte Skein256 on the processor. |
