Trust model for Public Key Infrastructure in the real-world environment
真实应用环境下的PKI信任模型

Through reasoning about PKI trust model, researchers can learn more about the establishment and transfer of trust relationships in PKI systems. Based on the existing models, we proposed a set of trust logics with practical predications and trust parameters. By utilizing these logics, we have extended the derive formulas for entity's authentication and authorization and analyzed the relationship between PKI structure and trust probabilistic.
