Research For USB Key Applications In Linux

Enter into the 21 century, Network become more and more osculation with human life. Computers are also become more and more embed the every side of people' s life. But, while they take great convenient for prople' s living and working. They also come with some security problems.The computer system' s frailness were acquit in the high storage density of data, accessing-able of data and easy to been leak, information remnant on media and the bugs of system. All these specialty bring on all the security problems that the computer system have to face. With the develop of the computer science and network technology, more and more production depend on these technology. In factories, most of the automatic equipments achieve auto-control by computer system, harmonize they work by network. Today, the industry computers' s hardware were strong enough for their job. But the operation system or the sofeware system that run on these computers were still not strong enoughIn this article, we introduced the USB Key equipment and the PKI encrypt arithmetic, and introduced the knowledge about the USB technology and the Linux operation system. In allusion to the fact of the industry computers, advance to choose an appropriate encrypt arithmetic and use the USB Key to archieve the identity authentication and other appliance on the industry computers. We also finished the IC select and the hardware design. At last, we expectation the more research and appliance of the USB Key in Linux.
