摘　　要：针对现有安全文件系统存在的问题设计一个面向容灾的强安全性虚拟文件系统。基于Linux平台,采用虚拟存储技术,借鉴堆栈式文件系统的实现原理,通过添加认证鉴别层、审计监控层、访问控制层、透明加密层以及容灾层,实现一个集强安全和容灾于一体的虚拟文件系统。This paper makes a brief analysis about the existing secure file system, and in the view of the problems of these secure file system, this paper designs a kind of disaster-oriented strong secure file system, The system is based on Linux. and it introduces the technology of virtual storage. According to the rationale of stackable file system, it addes the layers of authentication, audit, access control, transparent encryption and disaster tolerant to implement virtual file system which integrates disaster tolerant and strong security.
