1、華中科技大學(xué)碩士學(xué)位論文基于機(jī)器碼的軟件保護(hù)加密方案研究與設(shè)計(jì)姓名:藺吉睿申請學(xué)位級別:碩士專業(yè):軟件工程指導(dǎo)教師:蘇曙光2011-01-11Abstract Intellectual property protection and the prevention of software piracy is not a new topic. Every successful software vendors are targeting t
2、he major piracy. Because computer software is intellectual product, so can easily be copied, the software piracy to the global computer business has brought huge economic losses. At present, the software protection metho
3、ds are technically and legally related to the protection of the software made. In 1991 the State Council issued the “Computer Software Protection Regulations of the PRC. “ However, only legally be regulated, and violatio
4、ns can not contain the software. The most direct and effective way is to apply technology to the protection of software products, currently there are a variety of software protection technology, such as the serial number
5、 protection, time limit, KeyFile protection, software and dogs. These methods have advantages and disadvantages, a simple encryption method is very easy to be pirates will crack. Software cracking tools There are many, s
6、uch as dynamic analysis tools, static analysis tools, search tools, shell and back shell. The main topic of how to use native code to achieve the extraction of computer software protection purposes. Extraction of hard dr
7、ive serial number used as a way to generate machine code.Project will study how this method application in the enterprise, through the development of an effective mechanism to make the software license key generated to m
8、aintain the confidentiality of producers, users can not be inferred under the registration code software encryption. By comparing the information on this topic using a variety of hardware to read the hard disk serial num
9、ber of ways to generate machine code. By RI(Encoder) and decryption machine (Decoder) software used in conjunction to achieve the purpose of protection. Decryption key for this program was written in the executable file
