智能卡的功耗分析是密码学应用的一个真实的威胁。尽管以前的对策不断努力，最近改进的和复杂的攻击椭圆曲线密码系统不受保护。针对Goubin的精化功率分析（RPC）和Akishita-Takagi的零值点分析（ZPA）攻击，提出了两种新的对抗方法：随机线性变换坐标（RLC）和随机初始点（RIP）。所提出的对策在不降低安全级别的情况下，实现了显着的加速。
The power analysis on smart cards is a real threat for cryptographic applications. In spite of continuous efforts of previous countermeasures, recent improved and sophisticated attacks against Elliptic Curve Cryptosystems are not protected. This paper proposes two new countermeasures, the Randomized Linearly-transformed Coordinates (RLC) and the Randomized Initial Point (RIP) against the attacks including the Refined Power Analysis (RPC) by Goubin and the Zero-value Point Analysis (ZPA) by Akishita-Takagi. Proposed countermeasures achieve notable speed-up without reducing the security level.
