当前高能物理科学计算模式融合了机群计算、网格计算、云计算等多种跨地域的联盟计算模式，网络、计算资源、数据传输过程等均面临着巨大的网络安全风险，同时，在包括网格计算和云计算模式下，任何环节的安全问题均有可能导致更大范围的安全事件发生，并给高能物理研究本身造成很大的影响。本课题根据高能物理科学计算环境面临的关键安全问题，对高能物理领域科学计算环境中可信网络环境建立、计算节点可信接入及可信度量、远程可信证明机制及数据传输过程中的可信路由等关键技术展开研究，保障高能物理科学计算环境的安全可靠运行。

The cluster computing, grid computing, cloud computing and other technologies and models are widely used in energy physics scientific computing. There are always many security threats in the network,computing resources and the data transfer, and any security incidents will cause bigger influence to the scientific computing system. This paper focuses the key technologies on the establishment of the trusted network, trusted access, credibility, measurement and remote attestation mechanism for computing nodes and the trusted routing mechanism for the data transmission to ensure the safe environment for the high energy physics scientific computing system.
