Low-Complexity Parallel Systolic Architectures for Computing Multiplication and Squaring over GF(2(superscript m)

並列摘要


Recently, cryptographic applications based on finite fields have attracted much interest. This paper presents a unified systolic multiplier under the method of the multiply-by-x² and the folded technique. This circuit is particularly suitable for implementing multiplication and squaring in GF(2(superscript m). The results show that our proposed multiplier saves up to 75% space complexity and 50% latency as compared to the traditional multipliers proposed by Yeh et al. and Wang-Lin. Also, the proposed squarer saves about 45% space complexity as compared to the traditional squarer presented by Guo and Wang.
