中文摘要：

提出了一种基于网格环境的可信计算平台共享模型以提高可信与非可信节点混合环境下的整体安全性.模型允许非可信网格节点借用可信节点的可信平台模块及其核心服务以提高自身参与网络协同的可信程度,有助于提高当前网格环境中可信应用的范围.在模型中同时设计了远程协商协议、密钥迁移协议、验证和证明协议来解决共享过程中的交互问题.分析表明使用本模型可以平衡网格的安全性与代价,降低可信计算应用的门槛.

英文摘要：

A network environment based sharing model for trusted computing platform,a scheme called grid trusted sharing model(GTSM) was proposed to improve the holistic security in the environment mixture of trusted and untrusted platforms.In this model,untrusted grids could use the trusted grids of trusted platform module and its core services to improve untrusted grids′ participation and the trust of the coordination with the network.Three protocols,including remote agreement,key migration,verify and Attestation we...
