| 摘 要： | We introduce the general AC( attribute certificate ), the role specification AC and the role assignment AC. We discuss the rolc-based PMI(Privilege Management Infrastructure) architecture. The role-based PMI(Public-Key Infrastructure) secure model for E-government is researched by combining the role-based PMI with PKI architecture (Public Key Infrastructure). The model has advantages of flexibility, convenience, less storage space and less network consumption etc. We are going to use tbe secure model in the E-government system.
