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.
