Abstract: 提出了一种新型的基于构造输入点y坐标的CSPA方法,使得ECC密码算法中标量乘的点加和点倍运算产生明显的能量消耗差别,从而获取密钥信息.对多种ECC密码算法不同实现的芯片的实际分析结果表明,该方法具有较强的实用性,能够有效地识别出标量乘运算过程中的点加运算.研究提到的方法均在素数域的ECC密码算法上实现.
English Abstract: Chosen-message side-channel analysis attacks for public-key cryptosystems based on scalar multiplications was proposed, where special input point P is chosen to have the features of special y-coordinate to generate noticeable variations on power consumption or other side-channel information, between point doubling and addition operations, rendering distinguishable key bit information. Experimental results demonstrate that the proposed chosen message with simple side channel analysis method could effectively generate the noticeable variations. The method applies to the prime filed ECC cryptographic algorithms.
