The technical progress and the development of computer, causes the people to pay more and more attention to the information security. hacker's wildness along with virus for years, the information risk had been known by more and more enterprises, the importance of information security obtained takes generally.The portable security data processor is one kind of multi-purpose data security processing product. Its designed application mainly aims at the microcomputer data message to carry on processing and the storage, it has the basic function that ordinary U disk has, but also added the password safeguarding, data encryption and so on, with fine the contour design, It is the new generation of computer information security product. Its security manifests the decipher function and the corresponding smart card backend control which has in processor itself. The smart card backstage management, system management system is this product realization data secure foundation, it can guarantee the product uniqueness and the recoverability of self-destruction function.At present, the market has not appeared the data security product which this kind of smart card and the U disk unifies. More and more attention paied in the information security , this kind of smart card security processor is published certainly can give the data the secure storage to bring the new breath. My goal explores the new technical path which a information security stores. If we apply the smart card dual certification system in the U disk secure storage, certainly we can find a new solution of information security. The contact type smart card and U scrutinize the union, the key, the ID number, and personal PIN save in the IC card , we can changes the U disk use permission through the card recognition and the status certification, the administrator rank permission may turn on the U disk the security area, by achieves the target of data security. We also have implemented the U disk data encryption and the U disk self-starting and so on, the hard disk data encryption are through the IC Card's DES encryption key and in the ID number, this function has the broad application; Self-starting is a special characteristic, convenient user's safety handling.This topic's main research content as follows:1) I design the smart card security processor overall plan, but also prepares the associated information , including USB1.1 protocol , MASS STORAGE large-scale floppy disk mass memory protocol, ST72651 monolithic integrated circuit function white paper, 21st century science company's COS system and...
