基于可信计算的云用户安全模型

随着云计算的发展,它的安全问题不容忽视。根据云用户所面临的数据安全及身份的隐私性问题,提出了基于可信计算的云用户安全模型。安全模型以可信计算技术为支撑,除了采用传统的安全策略外,提出了建立私有虚拟机,为用户提供一个私密的运行空间,防止其他恶意用户或管理员访问该虚拟机;给出了用户信息匿名化的方法,当高安全级用户申请服务和变更服务时保证用户身份信息的私密性,防止服务提供商恶意利用和泄露用户信息,为用户提供一个安全的运行环境。

Based on Trusted Computing User Security Model for Cloud Computing

With the community＇ recognition fop cloud computing,its security can＇ t be ignored. Based on user facing data security and privacy issue,this paper gives Based-on trusted computing traditional security policy,proposed the establishment other malicious users or administrators to access cloud user of private the virtual security model, this virtual machines, to model bases on trusted provide user with the computing technology,in addition operation of a private space ,to machine;and gives a anonymous method of user information,when the user to the prevent applys services and change services to ensure the privacy of user information ,to prevent service providers malicious use and disclose user information ,to provides ＆ safe environment for user.
