Architecture of planar protective secure file system
一种二维防护的安全文件系统体系结构

After analyzing the characteristics of traditional security file systems,it was pointed out that these systems have several problems in data availability and system performance.Then a new architecture of security file system was proposed based on stackable file system to integrate the security services that a storage system should provide.The experimental results show that the new system makes a good tradeoff between security and performance.
