摘　　要：设计了一种基于混合信任链和特征预制的主动度量模型(mixed-chain&character pre-setting activemeasurement model,MC-CPSAM)。针对TCG信任度量机制存在的安全问题,MC-CPSAM对传统的链式信任结构进行改进,同时加强了对度量者自身完整性的保护,通过提高度量者权限,增强度量的主动性,实现自发的不受度量客体影响的信任度量机制,给出了一种基于MC-CPSAM模型的可信计算平台硬件结构例化,通过安全性证明说明模型满足信任链建立的原则。This paper designed a kind of active measurement model named mixed-chain ＆ character pre-setting active-mea- surement model（MC-CPSAM）. By making improvement of the traditional chain structure of trust, MC-CPSAM made the met- ric agents more trusted. It made an achievement for a kind of active measurement by protecting metric agents and upgrading rights of metric agents. At last, it designed a hardware structure based on MC-CPSAM and made an attestation for the security of this model.
