基于可信计算技术的抗恶意代码攻击模型

通过对恶意代码攻击过程的分析,针对恶意代码攻击的类型手段,研究信任链传递技术、基于密码的安全隔离技术、多级安全访问控制技术以及安全管道域技术。信任链传递技术解决可信计算基不能被篡改的问题,基于密码的安全隔离技术解决可信计算基不能被绕过的问题,多级安全访问控制技术解决普通用户信息交互的完整性和保密性问题,安全管道域技术解决特权用户使用资源的范围问题。最后,在此基础上构建基于可信计算技术的抗恶意代码攻击模型,并分析该模型的效能。

Anti-Malicious Code Attack Model based on Trusted Computing Technology

Through the analysis of the malicious code attack process,and aiming at the types and means of malicious code attacks,exploration is done on trust chain transfer technology,password-based security isolation technology,multi-level security access control technology and security pipeline domain technology.Trust chain transfer technology solves the problem that the trusted computing base cannot be tampered with;password-based security isolation technology solves the problem that the trusted computing base cannot be bypassed;multi-level security access control technology solves the problem of the integrity and confidentiality of information interaction of ordinary users;the security pipeline domain technology solves the problem of the range of resources used by privileged users.Finally,on this basis,an anti-malicious code attack model based on trusted computing technology is constructed,and the effectiveness of the model also analyzed.
