椭圆曲线加密(ECC)由于在安全性和计算量方面的优势,已被越来越多的人所青睐。ECC取代RSA成为新一代领头的公钥密码体制成为一种大的趋势。能量分析攻击的提出对智能卡的安全性提出了新的挑战。本文将研究椭圆曲线的简单能量攻击(SPA)和差分能量攻击(DPA)及其相应的防范措施。
Elliptic Curve Encryption (ECC) has been favored by more and more people due to its security and computational advantages. ECC replaces RSA as a new generation of leading public-key cryptosystems has become a big trend. The proposed energy analysis attack poses new challenges to the security of smart cards. This article will study the simple energy attack (SPA) and differential energy attack (DPA) of elliptic curves and their corresponding precautionary measures.
