【摘要】:隨著信息技術(shù)突飛猛進(jìn)的發(fā)展和電腦的廣泛普及,使得信息安全越來(lái)越受到人們重視。目前,針對(duì)信息的保護(hù)主要依賴于系統(tǒng)的安全和網(wǎng)絡(luò)的安全。本文主要是針對(duì)系統(tǒng)中文件的安全進(jìn)行探討,而目前信息大都是以文件的形式存放于計(jì)算機(jī),如何設(shè)計(jì)一個(gè)系統(tǒng)能夠加強(qiáng)對(duì)文件資源的有效保護(hù),成為我們研究的重點(diǎn)內(nèi)容。信息時(shí)代的一個(gè)重要特征就是大量的數(shù)據(jù)都以電子化的形式存儲(chǔ)在各種設(shè)施中。磁盤存儲(chǔ)設(shè)備是計(jì)算機(jī)的主要數(shù)據(jù)存儲(chǔ)設(shè)備,存儲(chǔ)著大量的機(jī)密信息和重要數(shù)據(jù)的磁盤,,由于遺失、被盜或者被非法訪問(wèn)磁盤存儲(chǔ)設(shè)備而引起的機(jī)密信息和重要數(shù)據(jù)的泄漏,導(dǎo)致政府、企業(yè)和個(gè)人遭受了巨大的損失。 本文分析了磁盤加密軟件TrueCrypt,分析了其透明加解密的原理,同時(shí)本文還分析了可信計(jì)算的基本思想,在基于虛擬磁盤管理技術(shù)及透明加解密磁盤軟件TrueCrypt的基礎(chǔ)上,結(jié)合可信計(jì)算的基本思想,利用USBKey作為可信度量根,設(shè)計(jì)了采用USBKey的可信磁盤加密系統(tǒng)。通過(guò)使用USBKey作為可信度量根實(shí)現(xiàn)加密磁盤的可信性。 在數(shù)據(jù)安全性方面,對(duì)于數(shù)據(jù)磁盤,選擇在文件驅(qū)動(dòng)層次開(kāi)發(fā)上層過(guò)濾驅(qū)動(dòng)加解密程序。在這個(gè)層次對(duì)數(shù)據(jù)進(jìn)行加解密,既不需要考慮物理磁盤的分布情況,也不需要關(guān)心上層文件的信息,還可以兼顧磁盤的需求,簡(jiǎn)單便捷地實(shí)現(xiàn)對(duì)數(shù)據(jù)磁盤的全盤加密。 加密技術(shù)是解決存儲(chǔ)設(shè)備數(shù)據(jù)泄露題最直接、最有效的技術(shù)。磁盤以其體積小、容量大、速度快等特點(diǎn)成為了主流數(shù)據(jù)存儲(chǔ)設(shè)備,因此,磁盤加密從進(jìn)入二十一世紀(jì)以來(lái)就成為了信息安全行業(yè)研究的熱點(diǎn)。本課題的研究成果,對(duì)促進(jìn)信息化發(fā)展,提高信息安全水平都將起到積極的作用。
[Abstract]:With the rapid development of information technology and the wide spread of computers, people pay more and more attention to information security. At present, the protection of information mainly depends on the security of the system and the security of the network. This paper mainly discusses the security of files in the system, but at present, most of the information is stored in the form of files in the computer. How to design a system to enhance the effective protection of file resources has become the focus of our research. An important feature of the information age is that a large number of data are stored electronically in various facilities. Disk storage device is the main data storage device of computer, which stores a large amount of confidential information and important data, and leaks the confidential information and important data caused by the loss, theft or illegal access to the disk storage device. As a result, governments, businesses and individuals have suffered enormous losses. This paper analyzes the disk encryption software TrueCryptand the principle of transparent encryption and decryption. At the same time, this paper also analyzes the basic idea of trusted computing, based on virtual disk management technology and transparent encryption and decryption disk software TrueCrypt. Combined with the basic idea of trusted computing, a trusted disk encryption system based on USBKey is designed by using USBKey as the confidence root. The creditability of the encrypted disk is realized by using USBKey as the confidence root. In the aspect of data security, for data disk, we choose to develop the upper layer filter driver encryption and decryption program at the file driver level. In order to encrypt and decrypt the data at this level, we do not need to consider the distribution of the physical disk or the information of the upper file. We can also give consideration to the demand of the disk and realize the complete encryption of the data disk simply and conveniently. Encryption technology is the most direct and effective technology to solve the data leakage problem of storage devices. Disk has become the mainstream data storage device because of its small size, large capacity and fast speed. Therefore, disk encryption has become a hot topic in the information security industry since it entered the 21 century. The research results of this subject will play a positive role in promoting the development of information technology and improving the level of information security.
