| 摘 要： | 为了进一步丰富可信计算完整性验证机制,根据TCG规范中可信传递的思想,提出一种系统完整性度量模型,在执行前度量客体的完整性,防止恶意代码破坏系统完整性,实现信任从前一个实体传递到下一个实体,从而把信任链从运行环境延伸到应用空间.完整性度量模型扩展了现有安全模型的安全属性,它与其它安全模型的结合将能给系统提供更加细致和完善的安全策略. |
| 关 键 词： | 可信计算 可信传递 完整性度量 |

| Abstract: | In order to enrich further the integrity verification mechanism in trusted computing,a model of integrity measurement was presented based on the idea of transitive trust in the TCG's criterion.In the model,the execute right of an object was defined and specified strictly,and the integrity of the object was measured before execution.The model can prohibit malicious code from compromising the integrity of system and transit trust form one entity to next one,so that the chain of trust can be extended form the BIOS all the way to application layer.The model extended the security attribute of the present security model. |
| Keywords: | trusted computing transitive trust integrity measurement |
