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。 -
The author mainly realized the method of generating the large random numbers and judging the prime number using lehmann means, then three pairs of secure key with different lengths ( 256 bits, 512 bits, 1024 bits ) was generated to meet the demand of different security grade. in encryption module, modular multiplication arithmetic of large number was realized adopting addition chaining. in decryption module, extended euclid was used to get inverse, and the chinese remainder theorem was used to realize decryption, which increased the speed of decryption greatly
作者主要實現了大隨機數的生成、採用整除小素數和勒曼測試法判定素數，可以生成三種不同長度的密鑰對（ 256位、 512位、 1024位）來滿足不同的加密安全等級的需求；加密模塊中，選用了二進制序列的乘法方法，實現了大數模冪乘運算；解密模塊中，引用了擴展的歐幾里德法求逆元，並採用中國剩餘定理實現解密過程，大大提高了解密速度。
