摘　　要：纯粹的加密算法的应用对于边际信道的攻击的防御是比较弱的,椭圆加密算法是近年来人们认为加密能力比较强的算法之一。本文讨论了目前存在的增强椭圆曲线算法抗边际信道攻击的方法,就其可行性提出了一些看法,并对其中几种方法的时间、空间复杂度进行比较。最后探讨了此类研究的应用前景。Pure implementations of crypto-algorithms are susceptible to side-channel analysis? Elliptic curve cryptography is conside as one of power cryptography?In this paper, we talk about the known methods for preventing side-channel attack in elliptic curve cryptosystems?and prompt the feasibility of those methods?After the comparison on time and space complexity for some methord among them,we discuss this kind of study's future?
