【摘要】 提出了用安全的复杂信息系统体系结构模型(SCISAM)构建安全、互操作、可扩展的CIS。采用分层方式降低系统复杂度,利用Web Service实现互操作和可扩展,使用密码支撑层、安全防护与可靠性支持层保证系统安全,通过系统管理层实现可管理性。某电子政务案例及其性能统计和仿真证明该模型适用于高安全级别的系统。更多还原

【Abstract】 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.更多还原
