栅格化网络信任传递技术研究

栅格化网络对信息安全的要求愈加迫切，有必要对其信任传递技术进行研究和验证。构建面向服务的端到端业务访问的安全体系结构，提出栅格环境下跨域业务访问的安全防护等关键技术，形成基于业务属性为驱动的动态安全策略防护机制，实现不同类型业务的安全服务能力，有效地保证系统的可靠运转，为栅格化网络的建设保障提供有力支撑，并对后期的研究工作进行了展望。

Trust Transitivity Technique in Grid-Enabled Networks

The demand for information security in grid-enabled network becomes extremely urgent, so it as necessary to study and verify the trust transitivity technique. This paper describes the service-oriented se- curity architecture of end-to-end traffic access, proposes some key technologies, such as safety protections of cross-domain traffic access in the grid environment, then analyzes the dynamic security policy protection mechanisms based on the service property. As a result, different types of the security service capability could be achieved, and the system reliability be effectively ensured, thus to provide strong support for the construction of grid-enabled networks. Finally the future research work is forecasted.
