摘要
针对Ha等人提出的CRT-RSA防御算法进行了分析,指出其算法在使用中国剩余定理(CRT)的过程中仍然存在着降低计算效率的模逆运算。为了提高计算性能消除模逆运算,基于明文掩盖方法,提出了一种改进的安全CRT-RSA防御算法,并通过对改进算法的理论分析,证明该算法可抵抗现有已知的功耗攻击(SPA、DPA、RDA和(N-1)攻击)和故障攻击(FA)且不存在模逆运算,从而更加高效与实用。
In this paper,it＇s pointed out that Ha＇s scheme also involves an inverse operation during the recombination process by using CRT. Based on the idea of message blinding technique,an improved CRT-RSA signature scheme is presented against all known power attacks （SPA, DPA,RDA,and （N-I） attack） and fault insertion attacks （FA）. Furthermore, since the proposed scheme has no inverse operation and does not require any additional parameters, it is more practical and efficient due to the low computation load compared with other existing countermeasures.
