  2. Operation layer is the basic core part in elliptic curve encryption system including how to calculate elliptic curve ' s stairs is a large prime or including a large prime gene to ensure elliptic curve to be safe elliptic curve ; in this article safe elliptic curve is chosen by p1363 sae algorithm. besides, how to achieve fast point multiplication will influence the performance efficiency of the whole encryption system ; in this article, for different situations, signed binary method and rolling window method are respectively applied to perform quick operation of elliptic curve ' s point multiplication

    運算層是橢圓曲線密碼體制實現的最基礎、最核心的部分，包括如何來計算橢圓曲線的階為大素數或含有一個大的素因子，以保證所選取的橢圓曲線為安全橢圓曲線，本文根據ieeep1363協議的sea演算法實現了安全橢圓曲線的選取；另外如何實現標量乘的快速運算，將會影響整個密碼系統的實現效率，本文根據不同情況對橢圓曲線的標量乘法分別採用了帶符號的二進製法和滑動窗口法進行快速運算。
  3. Geometrical and physical meanings of difference surface are presented, and the parameters of tooth surface topographic deviations are derived. in addition, the complete mathematical formulae of the 0th, the 1st, 2nd order form deviations is proposed, and diagnostic parameters of each order form deviation is gotten by the least square method, which lead to evaluate the tooth surface topographic deviation quantificationally

  4. The difficulty in assessing growth high - tech enterprises is lack of comparable companies and historical data, effective methods to measure growth, and methods to define income exactly, etc. as the pioneering securities market has not been established in this country, if we want to apply market methods to growth high - tech enterprises assessment, we could only take enterprises in main securities market as reference and must adjust factors, say, methods to select referenced companies, value proportion multiple, option value of exchangeable stock

    成長型高新企業價值評估的難點在於缺乏可比公司和歷史數據，預測未來收益難度大，對成長性缺乏有效的度量方法，以及存在著收入確認問題等。利用市場法對成長型高新企業進行價值評估，由於我國目前尚未建立創業板證券市場，現階段的解決方案仍舊只能以主板市場的企業作為參照公司，但是要對參照公司的選取、價值比例乘數、可交易證券的期權價值等因素進行調整。
