A layered mechanism to actualize a secure operating system based on the Linux kernel is put forward. Many security models are brought to an effective integration. The security of the original Linux kernel is improved. 综合多种安全模型的优点,提出了一种基于Linux内核的安全操作系统分层实现机制,从而弥补原始Linux内核安全性较差的缺点,为安全性要求较高的场合提出了一种可行的方案。
Second, Adopting the micro-kernel and layered operating system structure was in favor of improving the reliability and maintainability of the code. 其二,采用微内核和层次化的操作系统结构有利于提高代码的可靠性和可维护性。
