摘　　要：提出了一种针对基于标量乘的公钥密码体制的攻击方法。由于小整数n阶点在点加和倍点运算时能够产生显著数值变化,即产生显著功耗变化,因此基于小整数n阶点的选择明文与简单功耗分析可以有效攻击椭圆曲线密码(ECC)这种基于标量乘的公钥密码算法。This paper proposes a method which attacks for public-key cryptosystems based on scalar multiplications, The inte- ger order point n can generate noticeable variations in continuous point doubling and point addition operations, which have signifi- cant power change. Therefore the chosen-message simple power analysis based on the integer order point n operations can effective- ly attack for public-key cryptosystems based on scalar multiplications such as Elliptic curve cryptosystems（ECC）.
