摘要
Almost all the important information is saved on physical media as files and managed by file system. Sofilesystem's security is an important promise to information security. We present a transparent cryptographic file sys-tem based on secure operating system(SecTCFS). The users do not aware the exist of the encrypting process. Au-thentication promises that valid user can access the files in the system.
