( 4 ) for the second hierarchy mentioned above, the key operation is the scalar multiplication, especially, the pairs of scalar multiplication used in certain practical elliptic curve cryptosystems
（ 4 ）對于第二層次的運算，關鍵是點元素的標量乘法運算，特別是在某些具體的橢圓曲線密碼體制中需要直接計算標量乘法對。 -
Ecc is considered to be an alternative to rsa. this article provides a brief description of rsa public key cryptography and the associated knowledge, in particular introduces non - supersingular elliptic curves e which is established on the finite field fp with p > 3, in - depth studies present existed scalar multiplication, further proposes an improved signed sliding window algorithm on ecc under the mixed coordinates, the improved algorithm compatible the advantage of the naf, has the least number of zero window and avoid a large number of inverse operation, successfully reduce scalar multiplication calculation
本文闡述了橢圓曲線及其相關知識，特別說明了建立在有限域fp （其中p是大於3的素數）上的非奇異橢圓曲線e ，深入研究目前已有的各種標量乘法，由此提出了橢圓曲線密碼演算法在混合坐標下改進的帶符號滑動窗口演算法，該演算法兼容了naf方法的優點，擁有最少數目的非零窗口數，又避免了域元素上的大量求逆運算，較成功地減少了標量乘法計算量。 -
