摘要
针对一些电力应用领域对文件存储和安全操作的要求,论文基于uCOSII并参照BLP安全模型开发了一个安全的嵌入式文件系统——esfs。该文件系统建立了内存中的文件映射机制,把对flash文件的操作放置到高速的内存中完成,并且把安全性体现到esfs各个模块中,具有无目录管理、具备安全性(C2级)、体积小等特点,特别适合于电力应用的底层控制应用领域。
According to the storing file and secure operations requirement in some electric application,this paper refers to the BLP security module and builds a secure and embedded file sytem esfs(embedded and secure file system) based on uCOSII.This file system builds file mapping mechanism in RAM,which realizes the operations on the files stored in flash in the high-speed RAM,and it realizes the security by dividing them into the modules of esfs.h is characterized by non-directory management,security and small size,which makes it is useful in the area of electric application specially.
