摘　　要：云计算具有跨域共享资源的特性,传统的"各自为战"的身份管理模式已不再适用于云环境中,需要采用新的身份管理模式,联合身份管理就是一种能够处理多个单位、大量应用并支持海量用户的公共身份管理方案。通过使用开放式认证系统或安全断言标记语言来利用别人的身份存储。不仅能够更好地进行日志记录和审计工作,同时还能降低与密码重置和安全访问现有的异构应用相关的成本。而且还能够清楚地了解安全态势,帮助企业实现集中式的、全范围的安全控制。Cloud computing features cross-domain resource sharing, and the traditional engagement at will＂ identity management mode is no longer suitable for cloud environment, thus it is necessary to adopt a new identity management mode. Joint identity management is a public identity management solution capable to handle multiple units, and large numbers of application, and support mass user. By using OpenID or SAML and taking advantage of others＇ identity storage, it could realize fairly good log record and audit work, while reduce the costs relevant to password reset and security access existing heterogeneous application. And thus the security situation could be clearly understood, this would be helpful to the enterprises for their centralized and full-range security control.
