基于层次存储结构的权能查找机制

Design of Capability Search Mechanism Based on Hierarchical Storage Structure

与传统系统相比,基于权能的系统可以在不完全信任程序的情况下安全地运行程序。从权能的概念入手,论述了权能的基本工作原理。针对现有顺序权能查找机制在查找效率方面的不足,设计出一种基于层次存储结构的权能查找机制,可提高安全系统的权能查找速度,进而提高整个系统的运行效率。

Compared to conventional operating system, the system which based on capability could run the program safety even though we may not fully trust it. This paper starts with the concept of capability, dis-cusses the basics of how the capability works, design a capability search mechanism which based on hier- archical storage structure for the existing capability search mechanism~ search efficiency is really low.
