| 摘 要： | 鉴于网格应用的特殊性即动态性、异构性和自治性,传统的授权机制难以满足网格应用的特殊需求.解决方案是社区授权服务机制.讨论了相关技术如网格安全基础设施、代理证书、委托与单点登录,着重研究了团体授权服务模式、实施机制及其典型应用案例.探讨了团体授权服务(CAS)的安全性问题.最后指出了实施可定制的CAS组件的迫切性.

| Abstract: | In consideration of Grid applications' particularity such as dynamic,heterogeneous and autonomic,it is difficult for traditional authorization mechanisms to meet these applications' special requirements.The solution is community authorization service (CAS).The related techniques such as Grid security infrastructure,proxy certificate,delegation and single-sign-on are discussed briefly.CAS model and its implementing mechanism and its typical applications are particularly emphasized.The security issues and responding methods are explored.At last,the impendence of implementing customized CAS based on component is declared. |
