摘　　要：以芯片中的椭圆曲线密码安全防护方法为研究对象,对目前常用的椭圆曲线密码安全防护方法进行分析,分别从侧信道攻击和故障攻击两个角度,整理和总结了与其对应的安全防护方法,并对每个安全防护方法的防护角度和防护效果进行了介绍。此外,对芯片设计者如何选用安全防护方法来安全实现椭圆曲线密码算法提出了建议。In this paper, the elliptic curve cryptographic security protection methods in the chip are investigated, and the commonly used elliptic curve cryptographic security protection methods are analysed, and the corresponding security protection methods are collated and summarised from the perspectives of side channel attacks and fault attacks respectively. In addition, the paper concludes with recommendations on how chip designers can choose security protection methods to securely implement elliptic curve cryptographic algorithms.
