Hidden Pe File-based Information Technology Research And Implementation,

The nineties of the 20th century,the technology of computer network and multi-media is rapidly expanding.The information of photoshop, word,sound and picture have rapidly transferred in the Internet. Network is a rapier, the developing Internet provides the quick and convenient service for people, but it also brings many security problems.The cryptography may solve the question of information secrecy and authenticity freely, but can't solve network attack of traffic analysis.It is a great excitement that the information hiding technique which acts as a new security technology in the field of information security. The PE information hiding technique is an important part of the information hiding technique.The research of information hiding technology based on PE has not only provided a new hiding-media,but also provided a new way for copyright protection. The main works are as follows:(1)The thesis summarizes the background of research and the situation in home and abroad academe about information hiding, Combining with development of information hiding technology based on PE, the thesis introduces basic theory of PE, including PE origin , form and analyses the PE structure frame detailedly. According to the characteristic of PE file format,it is a new thought that studies PE in the field of information hiding throughly.(2)After introducing the structure characteristic and theory of information hiding,the thesis researchs and designs the information hiding model based on PE.That is, information is encrypted and mixed by rijidael,and then hiden in the redundancy space of PE sections. The thesis brings forward one kind of the scheme hiding information based on PE, and analysises the safety.(3)The hiding system based on PE is exploited by using of Visual C ++ 6.0, compared the hiding file and the restoration file and verified the feasibility and validity of PE hiding system by the Compare It 4.0.It is state clearly that the system robustness is better.(4)The scheme of software copyright protection is put forward to in this thesis, which utilizes the theory of threshold secret sharing scheme,takes the copyright as secret information,hide the n shadows to the PE files through decollating the secret.The research shows that the scheme strengthen anti-aggressivity and survivability about copyright protection.The question of concentrating information of hiding and security is solved.The technology of information hiding covers many fields, multidisciplinary technique system, it relates to the concrete application closly, it leads to the diversity of research result and the imperfect, there are a lot of technology problems to be solved in the future.In this thesis the technology of software information hiding is a new research field. The technology based on PE will provide useful complement for software information hiding, it has vast research space and application prospect.
