As the amount of flash memory being used in embedded device is increased and embedded devices become more important in many computing environments, embedded file system security becomes more important issue. Moreover embedded devices can be easily stolen or lost because of its high portability. If the lost embedded device has very important information, there's no means to protect it except data encryption. For improving embedded devices' security this paper propose design and implementation of flash cryptographic file system. For this purpose YAFFS is used. By the modified YAFFS cryptographic file system, the security of embedded devices can be improved.
