摘　　要：本文设计并实现了一种以流加密算法为思想并结合智能IC卡技术的高速加密系统.通过矩阵群和基于地址的取数方法,本文设计并实现了伪随机序列产生算法,并将伪随机序列产生算法和智能IC卡结合在一起,将发生器的矩阵群及算法内置于智能IC中,为整个系统提供了安全保证.所产生的随机序列通过了FIPS140-2标准测试,智能IC卡芯片通过USB接口连接计算机,软、硬结合的方式保障了加密系统的安全和加密速度.A high--speed encryption system base on a stream encryption algorithm and smart IC card technology was proposed firstly and the pseudorandom series algorithms were designed and realized by matrix group and an address method in this paper. And then we have combined the pseudo--random series algorithm with smart IC card by putting the matrix group into the smart IC card. Doing it provides a security guarantee for the entire system. Finally, the pseudo--random series generator created in this paper was passed the FIPS140--2 standard test and the smart card IC chip was connected to the computer via the USB interface. An innovative method to combine a soft and hard design in cryptographic technology provides a tool to protect system security and encryption speed.
