Security is one of the most crucial issues to address in Internet and is of the same importance in the application of grid technology. As a critical component of grid security, the secure authen- tication needs to be well studied. In this paper, a two-step mobile agent based（TSMAB） authentication architecture is proposed based on Globus security infrastructure （GSI）. By using mobile agent （MA） technology, the TSMAB authentication architecture is composed of the junior-authentication and the senior-authentication. Based on the design and the analysis of TSMAB model, the result shows that the efficiency of grid authentication is improved compared with the GSI authentication.展开更多
为解决PK I信任体系互联互通问题,在对比分析现有PK I常用5种信任模型优缺点的基础上,借鉴已有信任模型,特别是桥CA模型的优点,提出了一个新的模型——多级桥CA信任(m u ltileve l bridge certificate au thority,M BCA)模型.阐述了多级...为解决PK I信任体系互联互通问题,在对比分析现有PK I常用5种信任模型优缺点的基础上,借鉴已有信任模型,特别是桥CA模型的优点,提出了一个新的模型——多级桥CA信任(m u ltileve l bridge certificate au thority,M BCA)模型.阐述了多级桥CA信任模型的基本原理及其构建方法,给出了其总体架构;在总体框架下,对其原型系统中LDAP服务器进行了设计;并结合具体项目对方案的可行性进行了实验验证和分析.实验证明了该模型的可行性,有望对我国PK I建设工程有所帮助.展开更多
