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,参照BLP安全模型设计了一个安全的嵌入式文件系统——esfs (embedded and secure file system)。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,并具有无目录管理、安全(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。

Abstract: According to the requirements for storing file and secure operations in some electric application, this paper refers to the BLP security module and builds a secure and embedded file system——esfs ( embedded and secure file system ). This file system builds file mapping mechanism in RAM, which operates the files loaded from flash in high-speed RAM. It is characterized by non-directory management, security and small size, which make it useful in the area of electric application specially.
