Control Management System Of Mobile Storage Media

With the wide use of mobile storage media, much security hidden trouble hasarisen, which leads to secret divulging accidents. This dissertation focus on solving thesafety problem that is caused by the use of mobile storage media. According to theactual demand of the work unit, the control and management over the mobile storagemedium will be studied.The dissertation deals with Cryptography algorithm, the system structure of Udisk and the structure of the USB driver. It mainly analyzes permutation codealgorithm, U disk file system structure and development methods of the USB driverbased on WDM in windows. Requirement analysis and module design for storagecontrol management system of mobile storage media haev been given. Based on VC++,the USB driver, U disk management module, transparent encryption module andsystem client of this control and management system are implemented. Meanwhile,mobile storage equipment registration, authorization, auditing and encryption functionhave finished. This system has been tested and tried out in the network of myaffiliation. The result of the test shows that the system has reached the demand of thedesign.
