Windows下軟件實(shí)名機(jī)制的設(shè)計(jì)與實(shí)現(xiàn)
[Abstract]:At present, the continuously upgraded virus, Trojan horse, spyware, advertising software and other malicious code to the vast number of enterprises and individual users caused great inconvenience and security problems, its harm is obvious to all. At the same time, malicious code and software abuse are closely related, software abuse makes malicious code have more opportunities to speed up the spread of malicious code. At present, there are many different precautions against malicious code, such as code signature, sandboxie technology, antivirus software and so on. These technologies have played a certain role, but there are still some shortcomings. In view of their shortcomings, this paper proposes a software real name mechanism based on PKI technology. Nowadays, more and more concepts of real name appear, such as real name of mobile phone, real name of network, real name of seeking medical treatment and so on. The functions of the software real names in this paper are similar to those of them. The software real names use public key cryptographic digital signature technology to "bind" the computer software and the unique identity information of its authors. The real-named software has the functions of anti-tampering and anti-repudiation. When the software is installed or run, the software can be authenticated in the computing environment. According to the result of the authentication, the software can be allowed to run or not. In this paper, a system security mechanism based on software real name authentication is designed. The mechanism is implemented on the PE file of Windows system. The software registry is used to audit all the software that needs to run in the system. The audited software can only run in the system. In this paper, the security strategy of software real name mechanism is described, and the implementation scheme of software identification module and software verification module under Windows environment is given, and the strategy of software hierarchical verification is put forward to improve the efficiency of software verification. The experimental results show that the software real name mechanism can check the legitimate source of the software, check whether the software has been illegally tampered with after the release of the software, effectively prevent the malware from running, and have obvious effect on ensuring the security of the computer system.
