摘要： 标量乘法是椭圆曲线密码体制的核心运算，它的有效实现是近年来信息安全领域研究的一个热点内容。借 助于标量的wMOH表示思想，利用混合坐标表示下直接计算2kQ+尸的策略，改进了基于滑动窗口技术的标量乘法 算法。分析表明，所得算法效率明显提升，并降低了存储需求，能有效提升ELL的实现效率。

Abstract: Scalar multiplication is the heart of elliptic curve cryptosystems. In recent years,how to realize efficient scalar multiplication is a research focus of information security field. 13y means of the wMOF representations of scalar and the direct computation 2kQ}P strategy,we modified the scalar multiplication algorithm based on sliding window technolo- gy. The analysis results indicate that the efficiency of the algorithms is improved obviously and the storage requirements arc reduced, and it can enhance the ECC's efficiency.
