Abstract: A high-speed encryption system base on a stream encryption algorithm and smart IC card technology was proposed firstly and the pseudo - random 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.
