摘　　要：以可信计算和信任管理为背景,考察密码学原语中所包含的信任传递语义,进而借助于目前较为成熟的密码学理论为信任传递机理进行建模,提出了信任传递语义模型的雏形,分析了多种典型数字签名原语中的信任传递语义。分析结果表明所提模型具有很强的概括能力。最后,展望了该模型在IP网络信任管理系统设计及分析中的潜在应用。Under the background of trustable computing and trust management, the semantics of trust transitivity in cryptographic primitives were concerned, and an embryo model was proposed. Further, by using the model as a tool, semantics of trust transitivity in several signature primitives are formulated. The results manifest that the proposed model has the capability to capture the semantics of trust transitivity in these sigature primitives. And finally, the prospect on potential applications of proposal in designing and analysis of trust management systems for IP networks was sketched.
