摘　　要：通过对可信计算进行深入的分析,并进行严格的逻辑推理证明,提出了基于进化理论的层信任模型。该模型在逻辑结构上定义了可信计算环境基本的信任链和可信层,并通过3个主要属性来描述可信度,物理结构上通过广电网的基于法定权利义务关系的可信根广播和在可信终端建立基于可信存储的可信根,来实现可信计算环境。该模型使得现有通用计算平台也适用于可信计算环境,提出了解决可信计算环境的外部性和公正性问题的方法,减少了可信终端主动防御带来的验证开销,用较小的代价实现了可信计算环境下可信计算实体可信度收敛。After deep analysis and rigorous logic reasoning of the trusted computing the trust model based on evolutionary theory in the trusted computing environment was established.Through the definition on trusted chain and trusted layer as well as description of credibility in three main attributes the logical structure was realized.Through trusted root broadcasting based on legal rights and obligations in broadcast networks and establishing trusted root based on trusted storage in trusted terminal physical structure in trusted computing environment was achieved.The implementations made the common computing platform suitable for trusted computing environment solved the external and fair issues in trusted computing environment and reduced validation overhead brought from proactive of trusted terminal.The convergence of credibility was realized in the trusted computing environment at the smallest costs.
