【摘要】：隨著計算機(jī)技術(shù)的飛速發(fā)展，USB存儲設(shè)備的應(yīng)用也越來越廣泛，U盤（U-disk）作為一種即插即用的USB設(shè)備，以其小巧攜帶方便、存儲容量大、性能可靠、傳輸速度快等優(yōu)點成為日常生活中必不可少的移動存儲設(shè)備。人們在享受U盤易用性的同時，也面臨著它帶來的一系列數(shù)據(jù)泄露問題，因此人們對U盤這種存儲信息介質(zhì)的安全要求也越來越高。 首先，本文分析了目前U盤在信息存儲領(lǐng)域中帶來的安全威脅和存在的安全問題，從硬件和軟件分析了U盤在控制和保護(hù)方面的國內(nèi)外研究現(xiàn)狀，并總結(jié)了它們的優(yōu)缺點。 其次，針對現(xiàn)有U盤安全存儲控制與管理研究方面的不足，提出了一種基于虛擬磁盤的U盤控制與管理系統(tǒng)（UCMS），通過把普通U盤制作成具有特殊格式的加密U盤來實現(xiàn)U盤的安全存儲與管理，此系統(tǒng)集身份認(rèn)證和數(shù)據(jù)透明加解密于一體，并提供了安全鎖定和申請外帶功能；接著，本文介紹了UCMS系統(tǒng)的總體設(shè)計過程，主要包括U盤格式的設(shè)計、U盤識別模塊的設(shè)計、數(shù)據(jù)加/解密的設(shè)計和U盤管理模塊的設(shè)計。其中，前兩種設(shè)計實現(xiàn)了加密U盤在非UCMS系統(tǒng)下是不被識別的和普通U盤在UCMS系統(tǒng)下也是不被識別的；數(shù)據(jù)加/解密模塊從虛擬磁盤驅(qū)動程序出發(fā)，實現(xiàn)了數(shù)據(jù)的透明加/解密；U盤管理模塊為用戶提供了良好的圖形管理工具。 最后，本文介紹了UCMS系統(tǒng)的實現(xiàn)過程，結(jié)合UCMS系統(tǒng)的總體設(shè)計，依次完成了加密U盤格式的設(shè)計、U盤識別模塊、數(shù)據(jù)加解密模塊和圖形界面管理模塊。圖形管理界面實現(xiàn)之后，對系統(tǒng)進(jìn)行了功能測試，測試表明本系統(tǒng)能夠?qū)崿F(xiàn)總體設(shè)計的集身份認(rèn)證和數(shù)據(jù)透明加解密的所用功能。
[Abstract]:With the rapid development of computer technology, USB storage devices are more and more widely used. As a kind of plug and play USB device, U-disk device is easy to carry, has large storage capacity and reliable performance. The advantages of high transmission speed have become an indispensable mobile storage device in daily life. While enjoying the ease of use of the U disk, people are also faced with a series of data leakage problems brought about by it. Therefore, the security requirements of U disk, a storage information medium, are becoming more and more high. Firstly, this paper analyzes the security threats and existing security problems of USB disk in the field of information storage, analyzes the status quo of control and protection of USB disk at home and abroad from hardware and software, and summarizes their advantages and disadvantages. Secondly, aiming at the deficiency of the existing U disk security storage control and management research, In this paper, a USB disk control and management system based on virtual disk is proposed. By making the ordinary U disk into an encrypted U disk with a special format, the security storage and management of the U disk are realized. The system integrates identity authentication and transparent encryption and decryption of data. Then, this paper introduces the overall design process of UCMS system, including the design of U disk format, the design of U disk identification module. The design of data encryption / decryption and the design of U disk management module. Among them, the first two designs realize that the encrypted U disk is not recognized under the non UCMS system and the ordinary U disk is not recognized under the UCMS system. The data encryption / decryption module implements the transparent encryption / decryption of the data from the virtual disk driver, and the U disk management module provides a good graphics management tool for the user. Finally, this paper introduces the implementation process of UCMS system, combining with the overall design of UCMS system, the design of encrypted U disk format and U disk recognition module are completed in turn. Data encryption and decryption module and graphical interface management module. After the implementation of the graphical management interface, the system is tested. The test results show that the system can realize the functions of set identity authentication and transparent encryption and decryption of data.
