云计算中身份认证技术研究

Research on Identity Authentication Technology in Cloud Computing

对于云平台中用户之间的安全性认证问题,在分析openstack云平台的平台架构、安全认证组件keystone、云计算中身份认证的主要安全性问题及当前云环境中主流的身份认证技术的基础之上,针对云平台下的统一身份认证机制及统一身份认证技术的漏洞,着重分析了OpenID身份认证的工作原理,提出了OpenID当前存在的安全性问题,并得出了一些改进方案。最后以OpenID改进技术为基础,在openstack平台上实现了身份认证技术。

For the security authentication between the user in question of cloud platform,based on the openstack cloud platform architecture,security authentication keystone components,the identity authentication of the main security issues in cloud computing and the current cloud environments mainstream identity authentication technology,aiming at the mechanism for unified authentication and unified identity authentication technology platform under the cloud of vulnerability,this article analyzed the work principle of OpenID authentication,presented currently existing OpenID security problems,and obtained some improvements.Finally on the basis of the OpenID improvement techniques,the identity authentication technology was realized on the openstack platform.
