Research on semantics of trust transitivity in cryptographic primitives

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.
