Storage Optimization Of Stackable Security File System

Security filesystems provide secure file sharing in an open network environment. Existing security filesystems only consider generic security functionality. By the research of storage optimization, this thesis tried to improve the performance of these security filesystems.This thesis categorized and summarized storage optimization technology. Based on the research of many storage optimization methods, this thesis designed a file feature oriented storage optimization system using stackable technology. Each method of storage optimization was implemented as part of the system. Furthermore, by the implement and performance testing of SmallFS and MFS, this thesis proved the importance of storage optimization for improving the performance and security of systems.
