| 摘 要： | 讨论了RSA算法在IC卡中的应用，以及在Ic卡中实现RsA算法的一种途径，即利用中国剩余定理(cRT)来简化大数乘方取模运算．该方法在Ic卡芯片上已经成功实现．测试结果表明，在Ic卡中运用这种方法实现的RsA算法其解密速度与同等条件下的Des算法的加解密速度相当.

| Abstract: | As an outstanding asymmetric cryptography,RSA algorithm has a lot of virtues and thus is well applied in the scope of IC card applications. The paper deals with the application of RSA in smart cards and the approach in which the modular exponentiation of huge number is simplified by using the Chi nese Remainder Theorem. We have already succeeded in completing RSA in IC cards. Results indicate that RSA algorithm applied in IC cards has the equivalent speed of DES algorithm with the same environment. |
