Abstract: Aiming at the security problem of E-government application, this paper proposes the government meta-organization model for extended Privilege Management Infrastructure(PMI) and the relevant mathematical description. The application development platform is constructed by using this model, and is applied to the practical project establishment. Application results show that this model can adapt to E-government applications security needs in changing environment, realize authorization management, and has high promotional value.

Key words: E-government, government meta-organization model, Privilege Management Infrastructure(PMI), application security
