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。
