| 摘 要： | 在基于Linux内核的分布式并行安全操作系统中,由于没有全局一致的用户鉴别和访问权限管理机制,对系统的安全带来危害。该文在对用户权限验证机制进行分析的基础上,给出了由全局同步算法和用户信息一致性协议组成的实现用户一致性的算法。通过测试表明该算法可以有效地保证系统的用户一致性。

| Abstract: | In the Linux kernel-based Distributed and Parallel Security Operating System (DPSOS), the system security is not assured because of the lack of global user identification and access right managing mechanism. On the basis of analyzing the mechanism of user authority verification, this paper presents an algorithm to achieve the user consistency. This algorithm consists of global synchronizing algorithm and user information consistency protocol. Through tests, it has been proved that the algorithm can guarantee the user consistency of the system effectively. |
