摘　　要：Based on the structure of the side channel attacks （SCAs） to RSA cryptosystem can resist the fault attack and combine with the randomization method for the message and secret exponent, a new implementation scheme of CRT-based （the Chinese remained theorem） RSA is proposed. The proposed scheme can prevent simple power analysis （SPA）, differential power analysis （DPA） and time attack, and is compatible with the existing RSA-CRT cryptosystem as well. In addition, an improvement for resisting fault attack is proposed, which can reduce extra computation time.基于方面隧道攻击(SCA ) 的结构到秘密成员系统能抵抗的 RSA 差错攻击并且为消息和秘密代表与随机化方法结合，一个新实现计划基于 CRT (中国仍然是的定理) RSA 被建议。建议计划能阻止分析(矿泉) ，微分力量分析(DPA ) 和时间攻击的简单力量，并且也与存在 RSA-CRT 秘密成员系统兼容。另外，为抵抗差错攻击的改进被建议，它能减少额外的计算时间。
