专用安全操作系统

随着Internet的高速发展，安全问题显得日益重要。而计算机操作系统是信息系统的安全基础，但传统的操作系统安全机制已缺乏足够的灵活性，不能提供面向分布式环境的，可根据具体应用系统配置特定安全策略的机制。提出了一种专用安全操作系统的体系结构，用户可使用基于事件的高层定义语言来描述与进程相关的安全策略而无须关心底层细节，因此系统具有良好的适应能力和可扩展性。

A DEDICATED SECURE OPERATING SYSTEM

With the rapid development of Internet, the security problems have become more important. Computer operating system is the basis of information system security. But traditional operating systems lack sufficient and flexible mechanisms for application specific security policy of distributed system. In this paper, an architecture of dedicated secure operating system is proposed. User can define process specific security policy in a high level event based specification language regardless of low level details, so the system will have good adaptability and extensibility.
