With respect to removable mass storage device,the information security presents a nature that on one hand non-owners can't read the file when the owner of device lost it,on the other hand when the device can be operated in computer,computer virus should be prevent from tampering the data stored in device.This article design a security storage project based on FAT32 file system to meet these two demands.On one hand,the file stored in device can be encrypted;on the other hand,a UFI-like protocol is designed and the file system can only be operated by the client supporting the protocol so that the computer virus can't tamper the U disk.
