摘要：
A cryptographic method using an ECC(Elliptic Curve Cryptography) fast montgomery power ladder algorithm is provided to defend a cryptographic system against various attacks by actively managing a DFA(Differential Fault Analysis). A basic point and a scalar are received on an elliptic curve. The basic point is used for initializing plural first order variables. Plural second order variables are set corresponding to the first order variables. The first and second order variables are repeatedly calculated in response to the scalar such that a scalar product of the basic point and the scalar is obtained. Whether a fault is introduced to a system is determined by using the first order and second order variables in response to the scalar. If there is no fault, the scalar product is outputted.
摘要（中）：
提供了使用ECC（椭圆曲线密码学）快速montgomery电源梯形图算法的密码方法，通过主动管理DFA（差分故障分析）来保护加密系统免受各种攻击。 在椭圆曲线上接收基本点和标量。 基本点用于初始化多个一阶变量。 对应于第一阶变量设置多个二阶变量。 响应于标量重复计算第一和第二阶变量，使得获得基本点和标量的标量积。 通过使用响应于标量的一阶和二阶变量来确定故障是否被引入到系统。 如果没有故障，则输出标量积。
