基于扩展Client/Server分布式应用软件安全控制系统

结合3层Client/Server应用软件安全控制系统模型，提出了扩展形式的基于Client/Server的应用软件安全控制系统模型，增加了应用接口层和数据接口层，屏蔽了原模型各层间的模糊界限，使得各逻辑层的变动相互不影响.这有利于体系结构的建模与系统的一致性实现，增强了分布式应用的伸缩性和灵活性，并按4层Client/Server模式设计出该安全控制系统的框架，利用本系统的扩充Web服务器实现了Web上的安全验证.

Security Control System of Distributed Application Software Based on Extended Client/Server Model

By combining three-tier Client/Server application software security control system model, this paper puts forward a kind of security control system model of distributed application software based on extended Client/Server, adds application interface tier and data interface tier to original model, and screens fuzzy boundary between the tiers in the original model. This design makes every logical tier change alone, and helps to build model of architecture and to implement consistency of the system, further strengthens the retractility and flexibility of distributed application, then designs the frame of the security control system by using the model based on four-tier Client/Server. Finally, the security verification is implemented on Web by using extended Web server of the system.
