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 Chinese 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. 智能卡 芯片操作系统 信息安全 RSA算法 smart card chip operating system information safety RSA algorithm 10.14188/j.1671-8836.2000.03.014 TP309 国家自然科学基金!（699730 34）;湖北省自然科学基金!（99J030）资助项目 2000-03-01 2021-04-01 3
