A secure complicated information system architecture model is introduced to construct a secure,interoperable and extensible CIS.The model divides CIS into several layers to reduce system complexity.It uses Web service technique to realize the interoperability and extensibility.It introduces encryption support layer,security protection and reliability support layer to guarantee the system security and make the CIS administrable with system management layer.A study of E-government case with performance analysis and simulation proves that the model suits security-critical complex information system.
