          <datacite:description descriptionType="Other">本研究では，長い語長を有する剰余算術演算のため，SD (Signed - Digit) 数を用いた新しい剰余加算アルゴリズムを提案する．本提案のアルゴリズムでは，従来の剰余演算に用いられる法 m (2ⁿ-1&lt;m&lt;2ⁿ)の代わりに，剰余パラメータµ(=m-2ⁿ)を用いることで，n桁の剰余 SD 数加算を高速に行うことができる．そして，0.18µCMOS ゲートアレイ設計を前提とした剰余 SD 数加算器を内蔵した RSA 暗号処理プロセッサの構成を検討し，鍵のサイズを 2048 ビットとした場合でも，高速な暗号処理が実現できることを明らかにした．</datacite:description>
          <datacite:description descriptionType="Other">In this paper, we presented a new residue addition algorithm using Signed-Digit (SD) numbers for the applications such as RSA encryption with very long word-length. In the proposed algorithm, for the high-speed residue SD addition with n digits, a residue parameter : µ(= m — 2ⁿ) is used for the residue operation instead of using m(2ⁿ-1&lt; m &lt; 2ⁿ), which is the modulus in the residue arithmetic system. We apply the residue SD addition circuits to implement a RSA encryption processor by using a library with 0.18/µm CMOS VLSI technology. The design results show that high speed encryption can be achieved by using the proposed SD arithmetic architecture.</datacite:description>
